[Samba] AD Auth Trusted Domain issues

Greetings,
I figured out that since we made KID ADS native I have been able to
query for the SID successfully. I was unable to do that before. wbinfo
-n testuser actually returns a sid but it doesn't seem to want to map it
to anything so I am thinking my issue may be with how I am configuring
idmap. Any thoughts or suggestions?
Thanks,
-Paul
