Using something like 'getent group | grep <whatever>' is
unreliable and will always be.

However, we are trying to get you access via SMB or after
having logged in via pam_winbind even on heavily nested
group memberships. It might be true that we are not there
yet, but it is achievable.

This getent group thing does not work reliably, there's just
too many games you can play with group membership in AD.
There is one thing that should *always* work however: When
presenting the correct username and password to a domain
controller, it's this DC's task to untangle the group
memberships for us and present the correct group list in the
reply to the query whether user Joe has typed in his
password correctly. This is a completely different query
from listing the groups and figuring out the memberships

It might be possible that we don't yet make proper use of
the information the DC has figured out for us. If you have a
case where it fails against 3.0.23rc3, please file a bug
report at https://bugzilla.samba.org/ with debug level 10
logs of smbd and winbind. I know that there already is one
with a similar problem, I just did not yet get around to
really walk that stuff.
