The selinux gnu/linux user to selinux user mapping configuration file
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.
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.
