autofs-5.1.1 - fix return handling in sss lookup module
516ab0
516ab0
From: Ian Kent <raven@themaw.net>

516ab0
In the sss lookup module some of the calls don't distinguish between
516ab0
no entry found and service unavailable.
516ab0
516ab0
If service unavailable gets returned from a master map read it results
516ab0
in autofs not updating the mounts. A notfound return doesn't because it
516ab0
indicates the map doesn't exist so updating the mounts isn't a problem
516ab0
as it can be when the source is unavailable.
