How do I add users from Active Directory into Cognos Security?

[gingerhabasit]

Currently we use anonymous user login for Cognos, so everyone who clicks the link can see everything, and basically administer the system. I am new to Cognos security, and the person who installed the system originally has left the company.

I have created a namespace for Active Directory and it tests successfully. I am not sure what to do next, because in Cognos Administrator I can see the namespace but there is nothing in it. What is the next step in adding users from Active Directory to the namespace, so I can assign them permissions in Cognos?

I appreciate any assistance. Thank you!
