Created page with "'''$SETUAI''' is a system service that modifies the user authorization file (UAF) record for a specified user. =Syntax= SYS$SETUAI [nullarg] ,..."

New page

'''$SETUAI''' is a [[System Service|system service]] that modifies the [[SYSUAF|user authorization file (UAF)]] record for a specified user.

=Syntax=
SYS$SETUAI [nullarg] ,[contxt] ,usrnam ,itmlst ,[nullarg] ,[nullarg] ,[nullarg]

C prototype:
int sys$setuai (unsigned int efn, unsigned int *contxt, void *usrnam, void *itmlst,
struct _iosb *iosb, void (*astadr)(_ _unknown_params), int astprm);

=Privileges=
The following list describes the privileges you need to use the $SETUAI service:
* [[BYPASS]] or [[SYSPRV]] allows modification of any record in the [[SYSUAF|UAF (user authorization file)]].
* [[GRPPRV]] allows modification of any record in the UAF whose UIC group matches that of the requester. Note, however, that you cannot change a UAF record whose UIC matches exactly the requester’s UIC. Group managers with GRPPRV privilege are limited in the extent to which they can modify the UAF records of users in the same group; values such as privileges and quotas can be changed only if the modification does not exceed the values set in a group manager’s UAF record.

=Values Returned=

The following values are returened by $SETUAI:

{| class="wikitable"
! colspan="col" | Condition
! colspan="col" | Values Returned
|-
| SS$_NORMAL
| The service completed successfully
|-
| SS$_ACCVIO
| The item list or input buffer cannot be read by the caller; or the return length buffer, output buffer, or status block cannot be written by the caller
|-
| SS$_BADPARAM
| The function code is invalid; the item list contains an invalid item code; a buffer descriptor has an invalid length; or the reserved parameter has a nonzero value
|-
| SS$_NOGRPPRV
| The user does not have the privileges required to modify the authorization information for other members of the UIC group
|-
| SS$_NOSYSPRV
| The user does not have the privileges required to modify the authorization information associated with the user or for users outside of the user’s UIC group
|-
| RMS$_RSZ
| The UAF record is smaller than required; the caller’s [[SYSUAF]] is likely corrupt
|}
This service can also return OpenVMS RMS status codes associated with operations on indexed files. For a description of RMS status codes that are returned by this service, refer to the [https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-c04623189 OpenVMS Record Management Services Reference Manual].

=Arguments=
==nullarg==
OpenVMS usage: null_arg
type: longword (unsigned)
access: read only
mechanism: by value
Placeholding argument reserved to Compaq.

==contxt==
OpenVMS usage: longword
type: longword (unsigned)
access: modify
mechanism: by reference
A longword used to maintain authorization file context. The contxt argument is the address of a longword to receive a $SETUAI context value. On the initial call, this longword should contain the value –1. On subsequent calls, the value of the contxt argument from the previous call should be passed back in.

==usrnam==
OpenVMS usage: char_string
type: character-coded text string
access: read only
mechanism: by descriptor–fixed-length string descriptor
Name of the user whose UAF record is modified. The usrnam argument is the address of a descriptor pointing to a character text string containing the user name. The user name string can contain a maximum of 32 alphanumeric characters.

==itmlst==
OpenVMS usage: item_list_3
type: longword (unsigned)
access: read only
mechanism: by reference
Item list specifying which information from the specified UAF record is to be modified. The itmlst argument is the address of a list of one or more item descriptors, each of which specifies an item code. The item list is terminated by the item code 0 or by the longword 0.

The following diagram depicts the format of a single item descriptor:
bits 0-15: buffer length
bits 16-31: item code
buffer address
return length address

The following table defines the item descriptor fields:
{| class="wikitable"
! colspan="col" | Descriptor Field
! colspan="col" | Definition
|-
| Buffer length
| A word specifying the length (in bytes) of the buffer in which $SETUAI is to write the information. The length of the buffer varies, depending on the item code specified in the item code field of the item descriptor, and is given in the description of each item code. If the value of the buffer length field is too small, $SETUAI truncates the data.
|-
| Item code
| A word containing a user-supplied symbolic code specifying the item of information that $SETUAI is to set. The $UAIDEF macro defines these codes.
|-
| Buffer address
| A longword address of the buffer that specifies the information to be set by $SETUAI.
|-
| Return length address
| A longword containing the user-supplied address of a word in which $SETUAI writes the length in bytes of the information it actually set.
|}

=Item codes=
==UAI$_ACCOUNT==
Sets, as a blank-padded 32-character string, the account name of the user. An account name can include up to 8 characters. Because the account name is a blank-filled string, however, the buffer length field of the item descriptor should specify 32 (bytes).

==UAI$_ASTLM==
Sets the AST queue limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_BATCH_ACCESS_P==
Sets, as a 3-byte value, the range of times during which batch access is permitted for primary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_BATCH_ACCESS_S==
Sets, as a 3-byte value, the range of times during which batch access is permitted for secondary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_BIOLM==
Sets the buffered I/O count limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_BYTLM==
Sets the buffered I/O byte limit. Because the buffered I/O count limit is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_CLITABLES==
Sets, as a character string, the name of the user-defined CLI table for the account, if any. Because the CLI table name can include up to 31 characters plus a size-byte prefix, the buffer length field of the item descriptor should specify 32 (bytes).

==UAI$_CPUTIM==
Sets the maximum CPU time limit (per session) for the process in 10-millisecond units. Because the maximum CPU time limit is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_DEFCLI==
Sets, as an OpenVMS RMS file name component, the name of the command language interpreter used to execute the specified batch job. The file specification set assumes the device name and directory SYS$SYSTEM and the file type .EXE.
Because a file name can include up to 31 characters plus a size-byte prefix, the buffer length field in the item descriptor should specify 32 (bytes).

==UAI$_DEFDEV==
Sets, as a 1- to 31-character string, the name of the default device. Because the device name string can include up to 31 characters plus a size-byte prefix, the buffer length field in the item descriptor should specify 32 (bytes).

==UAI$_DEFDIR==
Sets, as a 1- to 63-character string, the name of the default directory. Because the directory name string can include up to 63 characters plus a size-byte prefix, the buffer length field in the item descriptor should specify 64 (bytes).

==UAI$_DEF_PRIV==
Sets, as a quadword value, the default privileges for the user. Because the default privileges are set as a quadword value, the buffer length field in the item descriptor should specify 8 (bytes).

==UAI$_DFWSCNT==
Sets, in pages (on VAX systems) or pagelets (on Alpha systems), the default working set size. Because the default working set size is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_DIALUP_ACCESS_P==
Sets, as a 3-byte value, the range of times during which dialup access is permitted for primary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_DIALUP_ACCESS_S==
Sets, as a 3-byte value, the range of times during which dialup access is permitted for secondary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_DIOLM==
Sets the direct I/O count limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_ENCRYPT==
Sets one of the values shown in the following table to identify the encryption algorithm for the primary password:

{| class="wikitable
! colspan="col" | Symbolic Name
! colspan="col" | Description
|-
| UAI$C_AD_II
| Uses a CRC algorithm and returns a longword hash value. It was used in VAX VMS releases prior to Version 2.0.
|-
| UAI$C_PURDY
| Uses a Purdy algorithm over salted input. It expects a blank-padded user name and returns a quadword hash value. This algorithm was used during VAX VMS Version 2.0 field test.
|-
| UAI$C_PURDY_V
| Uses the Purdy algorithm over salted input. It expects a variable-length user name and returns a quadword hash value. This algorithm was used in VMS releases prior to Version 5.4.
|-
| UAI$C_PURDY_S
| Uses the Purdy algorithm over salted input. It expects a variable-length user name and returns a quadword hash value. This is the current algorithm that the operating system uses for all new password changes.
|-
| UAI$C_PREFERED_ALGORITHM
| Represents the latest encryption algorithm that the operating system uses to encrypt new passwords. Currently, it equates to UAI$C_PURDY_S. VSI recommends that you use this symbol in source modules.
|}

Because the encryption algorithm is a byte in length, the buffer length field in the item descriptor should specify 1 (byte).

==UAI$_ENCRYPT2==
Sets one of the following values, indicating the encryption algorithm for the
secondary password. Refer to the UAI$_ENCRYPT item code for a description of
the algorithms.

==UAI$_ENQLM==
Sets the lock queue limit.
Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_EXPIRATION==
Sets, as a quadword absolute time value, the expiration date and time of the account.
Because the absolute time value is a quadword in length, the buffer length field in the item descriptor should specify 8 (bytes).

==UAI$_FILLM==
Sets the open file limit.
Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_FLAGS==
Sets, as a longword bit vector, the various login flags set for the user.
Each flag is represented by a bit. The $UAIDEF macro defines the following
symbolic names for these flags:

{| class="wikitable"
! colspan="col" | Symbol
! colspan="col" | Description
|-
| UAI$V_AUDIT
| All actions are audited.
|-
| UAI$V_AUTOLOGIN
| User can only log in to terminals defined by the Automatic Login facility (ALF).
|-
| UAI$V_CAPTIVE
| User is restricted to captive account.
|-
| UAI$V_DEFCLI

|-
| UAI$V_DISACNT
| User account is disabled. Same as /FLAG=DISUSER qualifier in AUTHORIZE.
|-
| UAI$V_DISCTLY
| User cannot use Ctrl/Y.
|-
| UAI$V_DISFORCE_PWD_CHANGE
| User will not be forced to change expired passwords at login.
|-
| UAI$V_DISIMAGE
| User cannot issue the RUN or MCR commands or use the foreign command mechanism in DCL.
|-
| UAI$V_DISMAIL
| Announcement of new mail is suppressed.
|-
| UAI$V_DISPWDDIC

|-
| UAI$V_DISREPORT
| User will not receive last login messages.
|-
| UAI$V_DISWELCOME
| User will not receive the login welcome message.
|-
| UAI$V_EXTAUTH
| User is considered externally authenticated by an external user ID and password and not by the SYSUAF user name and password. The SYSUAF record is still used for checking login restrictions and quotas and for creating the user’s OpenVMS process profile.
|-
| UAI$V_GENPWD
| User is required to use generated passwords.
|-
| UAI$V_LOCKPWD
| SET PASSWORD command is disabled.
|-
| UAI$V_MIGRATEPWD
| User’s SYSUAF password was set using AUTHORIZE or SYS$SETUAI and is likely to be inconsistent with the user’s external user password. If password migration is enabled, the system will attempt to update the external authorization service the next time the user attempts a login.
|-
| UAI$V_NOMAIL
| Mail delivery to user is disabled.
|-
| UAI$V_PWD_EXPIRED
| Primary password is expired. The UAI$V_PWD_EXPIRED should only be set when the bit UAI$V_DISFORCE_PWD_CHANGE is set in the user’s SYSUAF record and the comparison between the UAI$_PWD_DATE and UAI$_PWD_LIFETIME indicates a password is past its valid life.
|-
| UAI$V_PWD2_EXPIRED
| Secondary password is expired.
|-
|UAI$V_RESTRICTED
| User is limited to operating under a restricted account. Clear the CAPTIVE flag (UAI$V_ CAPTIVE), if set, before setting the RESTRICTED flag. (Refer to the OpenVMS Guide to System Security for a description of restricted and captive accounts.)
|-
| UAI$_JTQUOTA
| Sets the initial byte quota with which th
|}

==UAI$_JTQUOTA==
Sets the initial byte quota with which the jobwide logical name table is to be created. Because this quota is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_LASTLOGIN_I==
Sets, as a quadword absolute time value, the date of the last interactive login.

==UAI$_LASTLOGIN_N==
Sets, as a quadword absolute time value, the date of the last noninteractive login.

==UAI$_LGICMD==
Sets, as an OpenVMS RMS file specification, the name of the default login command file. Because a file specification can include up to 63 characters plus a size-byte prefix, the buffer length field of the item descriptor should specify 64 (bytes).

==UAI$_LOCAL_ACCESS_P==
Sets, as a 3-byte value, the range of times during which local interactive access is permitted for primary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight.
The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_LOCAL_ACCESS_S==
Sets, as a 3-byte value, the range of times during which local interactive access is permitted for secondary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight.
The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_LOGFAILS==
Sets the count of login failures.
Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_MAXACCTJOBS==
Sets the maximum number of batch, interactive, and detached processes that can be active at one time for all users of the same account. The value 0 represents an unlimited number. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_MAXDETACH==
Sets the detached process limit. The value 0 represents an unlimited number. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_MAXJOBS==
Sets the active process limit. A value of 0 represents an unlimited number. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_NETWORK_ACCESS_P==
Sets, as a 3-byte value, the range of times during which network access is permitted for primary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_NETWORK_ACCESS_S==
Sets, as a 3-byte value, the range of times during which network access is permitted for secondary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_OWNER==
Sets, as a character string, the name of the owner of the account. Because the owner name can include up to 31 characters plus a size-byte prefix, the buffer length field of the item descriptor should specify 32 (bytes).

==UAI$_PASSWORD==
Sets the specified plaintext string as the primary password for the user and updates the primary password change date. You must have SYSPRV privilege to set passwords for any user account (including your own). The UAI$_PASSWORD and UAI$_PASSWORD2 item codes provide the building blocks for designing a site-specific SET PASSWORD utility. Note that if you create such a utility, you should also set the LOCKPWD bit in the user authorization file (UAF) to prevent users from using the DCL command SET PASSWORD and to prevent the LOGINOUT process from forcing password changes. If you create a site-specific SET PASSWORD utility, install the utility
with SYSPRV privilege.
You must adhere to the following guidelines when specifying a password with UAI$_PASSWORD or UAI$_PASSWORD2:
* The password must meet the minimum password length defined for the user account.
* The password cannot exceed 32 characters in length.
* The password must be different from the previous password.
To clear the primary password, specify the value 0 in the buffer length field. When you use $SETUAI to change the password on an account that has the UAI$V_EXTHAUTH flag set, the UAI$V_MIGRATEPWD flag is set automatically.

==UAI$_PASSWORD2==
Sets the specified plaintext string as the secondary password for the user and updates the secondary password change date. You must have SYSPRV privilege to set passwords for any user account (including your own). To clear the secondary password, specify the value 0 in the buffer length field.

==UAI$_PBYTLM==
Sets the paged buffer I/O byte count limit. Because the paged buffer I/O byte count limit is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_PGFLQUOTA==
Sets, in pages (on VAX systems) or pagelets (on Alpha systems), the paging file quota. Because the paging file quota is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_PRCCNT==
Sets the subprocess creation limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_PRI==
Sets the default base priority. Because this decimal number is a byte in length, the buffer length field in the item descriptor should specify 1 (byte).

==UAI$_PRIMEDAYS==
Sets, as a longword bit vector, the primary and secondary days of the week. Each bit represents a day of the week, with the bit clear representing a primary day and the bit set representing a secondary day. The $UAIDEF macro defines the following symbolic names for these bits:
* UAI$V_MONDAY
* UAI$V_TUESDAY
* UAI$V_WEDNESDAY
* UAI$V_THURSDAY
* UAI$V_FRIDAY
* UAI$V_SATURDAY
* UAI$V_SUNDAY
* UAI$_PRIV

==UAI$_PRIV==
Sets, as a quadword value, the names of the privileges that the user holds. Because the privileges are set as a quadword value, the buffer length field in the item descriptor should specify 8 (bytes).

==UAI$_PWD==
Sets, as a quadword value, the hashed primary password of the user. Because the hashed primary password is set as a quadword value, the buffer length field in the item descriptor should specify 8 (bytes). When you use $SETUAI to change the password on an account that has the UAI$V_EXTHAUTH flag set, the UAI$V_MIGRATEPWD flag is set automatically.

==UAI$_PWD_DATE==
Sets, as a quadword absolute time value, the date of the last password change. Because this value is a quadword in length, the buffer length field in the item descriptor should specify 8 (bytes). A value of –1 indicates that the password could be marked as preexpired.

==UAI$_PWD_LENGTH==
Sets the minimum password length. Because this decimal number is a byte in length, the buffer length field in the item descriptor should specify 1 (byte).

==UAI$_PWD_LIFETIME==
Sets, as a quadword delta time value, the password lifetime. Because this value is a quadword in length, the buffer length field in the item descriptor should specify 8 (bytes). A quadword of 0 means that none of the password mechanisms will take effect.

==UAI$_PWD2==
Sets, as a quadword value, the hashed secondary password of the user. Because the hashed secondary password is set as a quadword value, the buffer length field in the item descriptor should specify 8 (bytes).

==UAI$_PWD2_DATE==
Sets, as a quadword absolute time value, the last date the secondary password was changed. Because this value is a quadword in length, the buffer length field in the item descriptor should specify 8 (bytes).
A value of –1 indicates that the password could be marked as preexpired.

==UAI$_QUEPRI==
Sets the maximum job queue priority in the range 0 through 31. Because this decimal number is a byte in length, the buffer length field in the item descriptor should specify 1 (byte).

==UAI$_REMOTE_ACCESS_P==
Sets, as a 3-byte value, the range of times during which batch access is permitted for primary days. Each bit set represents a 1-hour period, from bit 0 as midnight to 1 a.m., to bit 23 as 11 p.m. to midnight. The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_REMOTE_ACCESS_S==
Sets, as a 3-byte value, the range of times during which batch access is permitted for secondary days. Each bit set represents a 1-hour period, from bit 0 as
midnight to 1 a.m., to bit 23 as 11 p.m. to midnight.
The buffer length field in the item descriptor should specify 3 (bytes).

==UAI$_SALT==
Sets the salt field of the user’s record to the value you provide. The salt value is used in the operating system hash algorithm to generate passwords. $SETUAI does not generate a new salt value for you. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes). By copying the item codes UAI$_SALT, UAI$_ENCRYPT, UAI$_PWD, UAI$_PWD_DATE, and UAI$_FLAGS, a site-security administrator can construct a
utility that propagates password changes throughout the network. Note, however, that VSI does not recommend using the same password on more than one node in a network.

==UAI$_SHRFILLM==
Sets the shared file limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_TQCNT==
Sets the timer queue entry limit. Because this decimal number is a word in length, the buffer length field in the item descriptor should specify 2 (bytes).

==UAI$_UIC==
Sets, as a longword, the user identification code (UIC). For the format of the UIC, refer to the OpenVMS Guide to System Security.

==UAI$_USER_DATA==
Sets up to 255 bytes of information in the user data area of the system [[SYSUAF|user authorization file (SYSUAF)]]. This is the supported method for modifying the user data area of the SYSUAF. Compaq no longer supports direct user modification of the SYSUAf.
To clear all the information in the user data area of the SYSUAF, specify $SETUAI with a buffer length field of 0.

==UAI$_WSEXTENT==
Sets the working set extent, in pages (on VAX systems) or pagelets (on Alpha systems), specified for the specified job or queue. Because the working set extent is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).

==UAI$_WSQUOTA==
Sets the working set quota, in pages (on VAX systems) or pagelets (on Alpha systems), for the specified user. Because the working set quota is a longword decimal number, the buffer length field in the item descriptor should specify 4 (bytes).
