Thanks a heap for you clarification. Things are starting to work already.
I will get back with more info later. For now though, could you or someone
please clarify the format of the 'trusted domains=' line?
The way you mentioned it confused me a little. For example, my samba
domain is lxind, and my samba domain pdc is lxfsind. The nt domain is
ntfsind, and the nt pdc is fsind. Do I do trusted domains=ntfsind
or do I do something else? Thanks again.
