Hi,
I am having the exact same problem as the user quoted below - I have
3.0.28a installed at both ends (I've tried 3.0.30 but that seems to make
wbinfo -t fail with "DOMAIN CONTROLLER NOT FOUND" errors). It's a
bidirectional trust - the end remote to me works fine but the local end
reports as below. wbinfo -u/g fails on both ends with "Error looking up
domain users".
Here is the relevant part of my smb.conf on the local end:
