RE: Domain Trusts and Exchange Accounts

2002-11-19 Thread Atkinson, Daniel
We have four domains with a complete-trust model. Mailboxes have NT accounts
from any of these domains. No problems here...never had any issues sharing
calendars. This is exchange 5.5.

 Yes, maybe, especially if it is a mixed NT4.0 domain and AD setup. It will
 work but certain functions will not work in Outlook, like sharing of
 calendars can be troublesome.

  Hi,
 
  If you have two domains and they fully trust each other can an NT
 account
 in
  domain a be mapped to an exchange account in domain b?

RE: Domain Trusts and Exchange Accounts

2002-11-14 Thread Dupler, Craig
In any BackOffice system, all objects have to exist within a security
context.  All communications (the movement of bits) has to take place within
a security context.  In 5.5 and earlier, the security context is provisioned
or enforced independently of the existence of an Exchange Store mailbox.  In
E2K it is not.  A box must be linked to an AD entry.

So, in 5.5 and earlier, if a trust has been created, and the comlink is up
at the time of mailbox creation (oh yes, it has to be resolved!!!) then you
can indeed assign a mailbox to a security context on the other side of the
trust barrier.  In some ways, this is no different from what happens in
the AD, in that you can establish trusts or use certificates between
forests.  But I think you will find that the AD service has the ability to
cache trust data in a way that SAM could not, thus enabling some resolutions
to occur (if the right data is in the cache) even if a comlink is down.

One other small tidbit.  In order to make the architectures of SAM and AD
easier to understand, Microsoft uses context specific terms for things that
are not really different.  SAM has the ability to redirect a request to
another SAM.  It can do this to two levels.  It can't do it to a third.  The
AD works the same way, except it can permit greater levels of nesting in one
narrow instance (i.e. the request cannot be redirected again once it has
crossed a trust boundary).  We can give a specific machine the ability to
look to another specific machine's SAM or AD for data, we call that joining
a domain.  If the second machine relays the request a second time, we say
that that other machine (obviously a PDC or BDC) has a trust relationship.
But, it is really the exact same thing.  There is no meaningful difference
between a trust and domain membership, or being in a forest.

Maybe was the right answer.
