member managment software
 

I been looking all over for a decent membership management software package. Its to protect and admin a free site via htaccess. features needed allowing user to join user/pass and give em instant access via form based login. Admin functions need to allow add/delete /kill/ find /ban user etc
looking for an out of the box set ready to go. Tried a copy of Needlock but it wasent what i needed. Any usufull links then lemme know. Would be even better if it was database driven so we can track whos online who logged in when etc. Any ideas anyone, cause cant seem to find what i actually need :helpme

Thanks
