Hello ..

Does anyone have a description or hints on how to get Samba to see users
from two separate Windows ADS Domains/Forests ?

Here is the Situation :

Windows (Server 2003 R2):

  TEST.DOM  and DEMO.DOM in separate 'Forests'

  DEMO.DOM Win2003 ADS -> explicit incoming Trust from TEST.DOM
  TEST.DOM Win2003 ADS -> explicit outgoing Trust to DEMO.DOM

  ( TEST.DOM Trusts DEMO.DOM, but DEMO.DOM does NOT trust TEST.DOM )
  Windows AD in TEST and DEMO see each others users just fine

Linux (RHEL4, Debian):

  Samba 3.0.23d is joined to TEST.DOM and sees all Users and Groups from
  TEST.DOM - but not the Users from DEMO.DOM (wbinfo -u, getent passwd).

( If TEST.DOM and DEMO.DOM are in the same Forest - and therefore get a
  Two-Way Transitive Trust - Samba would see all users from TEST & DEMO
  Same if TEST.DOM and DEMO.DOM are in separate Forests and a Two-Way
  Explicit Trust is set up. )

net ads user -w DEMO -U user1%mypw
net ads user -w TEST -U user1%mypw

both will list the users from the respective Domain, therefore it looks
like it should be possible to get winbind lookup the users if given the
proper credential - the question is how ...

The simplest solution would be to establish a two-way Trust between the
Windows Domains, however, this is very likely not possible due to IT

Thanks a lot for any hints or pointers !

Kind regards,
