       The pam_sepermit module allows or denies login depending on SELinux enforcement state.

       When the users which are logging in match an entry in the config file they are allowed access only when
       SELinux is in enforcing mode. Otherwise they are denied access. For users not matching any entry in the
       config file the pam_sepermit module returns PAM_IGNORE return value.

       The config file contains a list of user names one per line with optional arguments. If the name is
       prefixed with @ character it means that all users in the group name match. If it is prefixed with a %
       character the SELinux user is used to match against the name instead of the account name. Note that when
       SELinux is disabled the SELinux user assigned to the account cannot be determined. This means that such
       entries are never matched when SELinux is disabled and pam_sepermit will return PAM_IGNORE.

       See sepermit.conf(5) for details.
