Hi

We are running AD 2003. We have multiple domains within the same forest - emea.kam.com and apac.kam.com, forest root kam.com

We have an application that will need to query AD to lookup attributes of users, their group membership and other info.

What port does the app need to query the DC on - 386 (LDAP) or 3268 (GC)?

It depends on what type of groups and what the other info is.  Look at the last section here   http://technet.microsoft.com/en-us/library/cc978012.aspx

The GC only holds a partial set of attributes so while a GC in emea knows about every object it doesn't contain every attribute for every object.

Thanks

Could you reveal the name of application,you are going to use in AD for performing ldap query.

The general attribute can be queried by most of the application using GC but if you want specific attribute, you require some set of programming/scripting to achieve that.

http://msdn.microsoft.com/en-us/library/ms675085%28VS.85%29.aspx

You will surely require 389 for ldap server & for secure 636(LDAP SSL)

Same for GC 3268 & 3269 for SSL.

It might require 53 for DNS server lookup.
