I am using ldap authentication and the user is authenticated but when returned to the main page from the logon page, I still see the users ip address rather than the user name and I still see the "LOG IN" button. I guess I am missing an extension to show the real name instead of the ip but I do not know which extension that would be and I am clueless as to why I authenticate but am not loigged in. I am new to MEdiaWiki so any help that would point me in the right direction would be appreciated.
