#CHANGEUSER Built-In Function

Use #CHANGEUSER to log on under a different user ID, keeping the current user’s

values.

CHANGEDEFAULTS

causes TACL to set its default node, volume, subvolume, and file security to that of

the new user instead of retaining the current user’s values.

group-name. user-name or group-id, user-id

is the group name and user name, or the group number and user number, of the

user who is logging on. The user identity must already have been established. If

you do not have a user account, see your system administrator.

If the TACL configuration NAMELOGON option is not set to 0, or if Safeguard is

running and the Safeguard NAMELOGON flag is not set to 0 (for the

USER_AUTHENTICATE_call), the group number and user number is not

accepted.

alias

is an alternate assigned name. Each alias must be unique within the local system.

An alias is a case-sensitive text string that can be up to 32 alphanumeric

characters in length. In addition to alphabetic and numeric characters, the

characters period (.), hyphen (-), and underscore(_) are permitted within the text

string. The first character of an alias must be alphabetic or numeric. For more

information on aliases, see the Safeguard Reference Manual.

password

is the password associated with the user.

Result

#CHANGEUSER returns -1 if it is successful; if not, it returns 0.

Considerations

•

If the USER_AUTHENTICATE_procedure exists in the system library, TACL calls

the USER_AUTHENTICATE_ procedure. USER_AUTHENTICATE_ uses the

Note. The LOGON command behavior depends on the Safeguard environment. If Safeguard

is not running on your system or if the USER_AUTHENTICATE procedure is not in the system

library, the alias option is not available
