New to MS Windows 2000 ADS security contexts is the fact that trust relationships are two-way
by default. Also, all inter-ADS domain trusts are transitive. In the case of the RED, WHITE and BLUE
domains above, with Windows 2000 and ADS the RED and BLUE domains CAN trust each other. This is
an inherent feature of ADS domains. Samba-3 implements MS Windows NT4
style Interdomain trusts and interoperates with MS Windows 200x ADS
security domains in similar manner to MS Windows NT4 style domains.

- Like many, I administer multiple LANs connected together using NT trust
- relationships. This was implemented about 4 years ago. I now have the
- occasion to consider performing this same task again, but this time, I
- would like to implement it solely through samba - no Microsoft PDCs
- anywhere.
- </p><p>
- I have read documentation on samba.org regarding NT-style trust
- relationships and am now wondering, can I do what I want to? I already
- have successfully implemented 2 samba servers, but they are not PDCs.
- They merely act as file servers. I seem to remember, and it appears to
- be true (according to samba.org) that trust relationships are a
- challenge.
- </p><p>
- Please provide any helpful feedback that you may have.
- </p><p>
- These are almost complete in Samba 3.0 snapshots. The main catch
- is getting winbindd to be able to allocate UID/GIDs for trusted
- users/groups. See the updated Samba HOWTO collection for more
- details.
