.SH "NAME"
pam_sepermit \- PAM module to allow/deny login depending on SELinux enforcement state
.SH "SYNOPSIS"
.HP \w'\fBpam_sepermit\&.so\fR\ 'u
\fBpam_sepermit\&.so\fR [debug] [conf=\fI/path/to/config/file\fR]
.SH "DESCRIPTION"
.PP
The pam_sepermit module allows or denies login depending on SELinux enforcement state\&.
.PP
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\&.
.PP
The config file contains a list of user names one per line with optional arguments\&. If the
\fIname\fR
is prefixed with
\fI@\fR
character it means that all users in the group
\fIname\fR
match\&. If it is prefixed with a
\fI%\fR
character the SELinux user is used to match against the
\fIname\fR
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\&.
.PP
See
\fBsepermit.conf\fR(5)
