Cognos BI 10.1.2 how to create a new user? -

i'm trying create new user in cognos bi 10.1.2.

after bit of research i've discovered new user must created in "authentication source" such example: ibm cognos series 7 namespace, active directory server, custom authentication provider, ldap, ca siteminder, racf, sap.

so question is, how setup "authentication source" , users create in authentication source shown in cognos connection web portal?
