<title>DESCRIPTION</title>
<para>
The pam_sepermit module allows or denies login depending on SELinux
enforcement state.
</para>
<para>
When the user which is logging in matches an entry in the config file
he is allowed access only when the SELinux is in enforcing mode. Otherwise
he is denied access. For users not matching any entry in the config file
the pam_sepermit module returns PAM_IGNORE return value.
</para>
<para>
The config file contains a list of user names one per line with optional arguments. If the
<replaceable>name</replaceable> is prefixed with <emphasis>@</emphasis> character it means that all
users in the group <replaceable>name</replaceable> match. If it is prefixed
with a <emphasis>%</emphasis> character the SELinux user is used to match against the <replaceable>name</replaceable>
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.
