User and Group Databases

UIDs and GIDs are stored in two databases: HPUID.PUB.SYS holds UIDs and related user information in a user ID database, and HPGID.PUB.SYS holds GIDs and related information in a group ID database.

These databases are privileged files that are transparent to users. The databases are automatically updated when you add, change, or delete users on the system by using the following commands:

   ALTACCT

   ALTUSER

   NEWACCT

   NEWUSER

   PURGEACCT

   PURGEUSER

The system automatically creates and maintains the user and group databases when you update to Release 5.0.

The complete user and group databases can be rebuilt using the RESTORE command with the DIRECTORY option. Refer to the section "Reloading Hierarchical Directories" in Chapter 8 for more information.
