Problem
You want to list the groups to which a user belongs.
Solution
To list a user’s group membership, use the [adsi] type shortcut to bind to the user in Active Directory, and then access the MemberOf property:
$user =
[adsi] "LDAP://localhost:389/cn=MyerKen,ou=West,ou=Sales,dc=Fabrikam,dc=COM"
$user.MemberOf
Discussion
The solution lists all groups in which the MyerKen user is a member. Since Active Directory stores this information as a user property, this is simply a specific case of retrieving information about the user.
