Ok, (finally) got an article up on OrionSupport about implementing a custom UserManager that authenticates user from your own database (Relational DB, XML, LDAP, NT Domains, proprietary app, etc). Provides you with a SimpleUserManager allowing you to hook it up to your own system by just implementing 3 methods. http://uk.orionsupport.com/articles/usermanager.html Hope it's useful. -Joe Walnes
