Provisioning to AD - in another forest

Hi,

I have tried to setup FIM2010 to provision users to AD (different forest).

While configuring the AD MA, have provided IP address in the place of server, and UPN for login and left the domin blank.

Have configured "Preferred DC" to use in the MA.

I am able to connect to AD, do a full synch. While running the export profile, I am receiving "cd-connectivity-errror" (stopped connectivity) .

However the users are getting created in disabled state (514 status).  There is no much load and I have tried to export one user only.

Am I doing something wrong. 

Regards

Sai
