seusers(5)                SELinux configuration                seusers(5)

NAME         top

       seusers - The SELinux GNU/Linux user to SELinux user mapping
       configuration file

DESCRIPTION         top

       The seusers file contains a list GNU/Linux user to SELinux user
       mapping for use by SELinux-aware login applications such as
       PAM(8).

       selinux_usersconf_path(3) will return the active policy path to
       this file. The default SELinux users mapping file is located at:
              /etc/selinux/{SELINUXTYPE}/seusers

       Where {SELINUXTYPE} is the entry from the selinux configuration
       file config (see selinux_config(5)).

       getseuserbyname(3) reads this file to map a GNU/Linux user or
       group to an SELinux user.

FILE FORMAT         top

       Each line of the seusers configuration file consists of the
       following:

              [%group_id]|[user_id]:seuser_id[:range]

       Where:
              group_id|user_id
                     The  GNU/Linux user id, or if preceded by the
                     percentage (%) symbol, then a GNU/Linux group id.
                     An optional entry set to __default__ can be provided
                     as a fall back if required.
              seuser_id
                     The SELinux  user identity.
              range
                     The optional level or range for an MLS/MCS policy.
