Subject: [PATCH] SELinux user maps: pick just one map
From: jzeleny () redhat ! com (Jan Zeleny)
Date: 2012-06-22 12:26:46
Message-ID: mailman.39.1340374360.2806.sssd-devel () lists ! fedorahosted ! org
[Download RAW message or body]
This patch modifies behavior of SSSD when putting together content of
the file for pam_selinux. SSSD will now pick only the first user map in
the priority list which matches to the user logging in. Other maps are
ignored.
