In K2.net 2003, you had to add entries in the different .config files (and especially K2Server.config) to allow the browsing of different domains (e.g. <DataSource Path="LDAP://DC=my,DC=domain,DC=com" NetBiosName="MY" Type="ActiveDirectory" />).
How can you do that in K2 Blackpearl? I need to give permissions to users from different domains of our organization, and when I want to do that in the Workspace, I can only browse the domain which the server belongs to.
