Ok, I increased the debug level as you recommended and it's given me a lot
of useful info. Before I go any further trying to troubleshoot that mass of
info on this mailing list though, I would like to double check something I
came across. In the debug output I noticed this line:

"No ccache file for user [b...@ad.bbg.net] found."

I then searched this error and found this thread in which the OP seems to
have basically the same setup as me:

https://lists.fedorahosted.org/pipermail/sssd-users/2013-January/000379.html

I started playing with kinit on the ubuntu machine that I'm trying to log
into, and got this error:

"kinit: Cannot find KDC for realm "AD.BBG.NET" while getting initial
credentials"

After reading through some of the replies on the above thread, I saw a post
that basically says that while the initial user info lookup is via FreeIPA,
to actually authenticate a user the ipa client machine must connect
directly to the AD controller. If this is true, it basically means the
setup I was planning to use (FreeIPA in the cloud replicating/proxying
local AD user accounts) is not going to work as I'd hoped. Could you
confirm if this behaviour is in fact correct?
Thanks,
Guy
