Im currently working on a intranet and trying to set up some security. The intranet acesses a SQL server 2000 database. I would like to know if there is a stored procedure(or other way) of returning all the domain groups that a user belongs to when passed the users NT login. I found xp_enumgroups which returns all the groups on the domain and also xp_logininfo which returns the users of a passed domain group. These are usful but i need to just pass the NT username and return all the Domain Groups. Any thoughts, ideas would be great!
