Using LDAP how to enumerate list of domains in a trusted forest?

Hi,

Using LDAP C interface, I am trying to enumerate list of all domains in a trusted forest.

One way I am using is to connect to GC of the trusted forest and enumerate for crossRef objects under Configuration partition of trusted forest root domain. But, this require bi-directional trust established just for reading.

To avoid bi-directional trust, just for reading list of domains, I am trying to find if there is any other way to do the same from some information within my forest. Looked at TrustedDomain object created for the forest. But TrustedDomain object doesn't seem to any references of domains in the trusted forest.

Thanks,

Lokesh
