Hello,
I recently had a need to use a wildcard certificate for a client setup
and ran into issues using it. I've attached a patch with some
modifcations I made to the 7.0.4 lib/tls.c source. I'm not really a C
programmer so it'd be great if someone else could run with it and make a
patch that could be added to Bacula.
