[Samba] ADS auth when primary AD server fails

The 3.0.20a version seems to have resolved the issue.  At the very
least, I am having a whole lot more luck when my primary goes down and
still authenticating to my AD domain.  

I am opening a bug with redhat to have them take a look at the issue
from their side of things.

Thank you for the help.

Is it possible for you to try 3.0.20a or (later this week) 3.0.20b ?
There are improvements in winbindd fallback code in those releases.
At least then we know we're working with the latest code base (winbindd
has had major changes on it between 3.0.10 and 3.0.20).
