Managing SELinux users

In order to grant a Linux login the right set of roles, we first need to create an SELinux user that has just those roles assigned. Existing SELinux users can be modified easily, and if an SELinux user was added previously, it can be removed from the system as well.

How to do it…

Managing SELinux users is done as follows:

    sysadm_u        user       s0         s0-s0:c0.c1023                 sysadm_r
