Like an idata file, a uidata file maps remote user logins to local logins; however, entries in a uidata file are specified by users themselves, not the system administrator.
A sample uidata file is shown below:
!M1@M2 joe@ulysses jfl mike@alpha mickey mike@beta mickey
When you enable user-controlled mapping, a user with logins on both a remote system and the local system can access the local system and make an entry in uidata that maps this user's remote login to a local login. By enabling user-controlled mapping and instructing users to update the database, an administrator can distribute the workload and minimize the administrative overhead. For more information about user-controlled mapping, see ``Enabling and disabling user-controlled mapping''.
uidadmin(1bnu) is the command interface to uidata. When you enter uidadmin, assuming user-controlled mapping is enabled, you can do the following as a non-privileged user:
The
uidadmin
command has the following syntax:
uidadmin [-S scheme [-l logname]]
uidadmin -S scheme -a [-l logname] -r g_name
uidadmin -S scheme -d -l logname [-r g_name]
uidadmin -S scheme [-cf]
See uidadmin(1bnu) for more details.
The options and command syntax required to execute a particular operation are described in the following sections.
