Subject: [PATCH] nss: Collision with external nss symbol
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

One of our internal static function names started
to collide with external nss symbol. Additional
sss_ suffix was added to avoid the collision.

This is needed to unblock Fedora Rawhide's
SSSD build.
