3.4 Linux User Management

Follow the guidelines given below:

  • Place the Unix Configuration Object (UCO) in the upper layers of the tree in a separate container (for example, ou=LUM,o=services) and maintain a single UCO per tree. For any additional server installation in the same tree, ensure that the existing UCO is utilized during LUM configuration in YaST.

  • Clean up the existing POSIX attributes on user and group objects before deploying the DSfW domain. The POSIX attributes include all the attributes that belong to the LUM schema extensions, such as uidNumber, gidNumber, homeDirectory, loginShell.

  • If you have modified the default POSIX ID ranges, ensure that they do not clash with the DSfW ID ranges. The LUM default UID and GID number for the DSfW domain ranges from 0 to 65500.
