Title Body

I'm using the System.DirectoryServices.AccountManagement to provide user lookup functionality. The business has several region specific AD domains: AMR, EUR, JPN etc. The following works for the EUR domain, but doesn't return users from the other domains (naturally): var context = new PrincipalContext(ContextType.Domain, "mycorp.com", "DC=eur,DC=mycorp,DC=com"); var query = new UserPrincipal(GetContext()); query.Name = "*Bloggs*"; var users = new PrincipalSearcher(query).FindAll().ToList(); However, if I target the entire directory, it doesn't return users from any of the region specific domains: var context = new PrincipalContext(ContextType.Domain, "mycorp.com", "DC=mycorp,DC=com"); How do I search the entire directory? Update Read up on "How Active Directory Searches Work": http://technet.microsoft.com/en-us/library/cc755809(v=ws.10).aspx If I suffix the server name with port 3268 it searches against the Global Catalog: var context = new PrincipalContext(ContextType.Domain, "mycorp.com:3268", "DC=mycorp,DC=com"); However it's very, very slow. Any suggestions on how to improve performance?
