One "e-mail domain" for some "external LDAP domains"

[ChaSer]

Hello!
There are some LDAP domains (Active Directories) - one for each buildings of our company.
All LDAP servers (domain controllers) and it's users connected in one phisical network by optical cable (100 Mb/s).
It is possible configure one ZCS 6.0.2 FOSS server for all users to use one e-mail domain like @corporatemail.xxx ?
Hint me, please!

Are these Active Directory servers separate domains or are they mirrors of each other? Will you be using these Active Directory servers to authenticate your Zimbra users against?

There are separate domains trees in separate Active Directory forests.

Question is a bit not clear to me. do you mean you want to do external auth for users in corporatemail.xxx on zimbra to all users in different forest and domains on legacy servers ?

Or is it something else

I want to do external Active Directory auth of all my users of some AD domain of some AD forests so users of diffrent organizations have similar e-mail like username@corporatemail.xxx.
In MS Exchange 2007 i get this by authorizating users in OWA (Outlook Web Access) by domain and user (domainname\username).

The only way that I can think of to get this type of setup working where you have multiple AD servers with multiple domains that you want users to just login as "user" and all be in the same domain in Zimbra would be to merge all the AD servers into a single virtual server under one domain, then use that as an external Authentication source.

Browsing the forum for something else I saw mention of this product: Penrose which might do that...

Understand though that I have no experience with any of this and am jsut guessing that this might work...
