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

NAME

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

DESCRIPTION

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

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.
