Well, there has to be a first time for everything, but whilst 'wbinfo'
doesn't need PAM, 'getent' certainly does.

I did the same and getent didn't work for me until I altered PAM.

I feel it must be a configuration problem, because I had it working
with Arch linux and the stock Samba packages.

Could it have anything to do with me being a member of the Samba
team ???

Whilst it might not be a configuration problem, this is unlikely,
unless you have altered the samba packages or have a mix up between the
various Samba packages that Arch provides.

I have it working, you say you have it working on test DC, it just
doesn't work on your main DC. All I can suggest is, see if you can see
any differences between the packages on your test machine and your main
DC, different versions, conf files etc.

I, or anybody else, cannot do any more than this, we do not have access
to your machines.
