List a Windows PowerShell User’s Group Membership

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.
