NetCmdlets doesn't have a long list of Active Directory cmdlets for PowerShell. Instead, it has 2. And they aren't AD specific - they just implement the LDAP protocol itself so they can work with any LDAP server, Active Directory or not.
Two cmdlets are all that is needed to make common tasks simple. One for setting values (set-ldap), and one for getting values (get-ldap).
Here's how I can retrieve a list of all the "admin" groups:
As you can tell, the get-ldap cmdlet is very flexible. I can specify any custom search scope and perform a search for any filter I like. This particular search filter searches for any groups that contain "admin" anywhere in the cn.
A more complete group search might have a search filter like so: "(|(|(|(objectClass=posixGroup)(objectClass=groupOfUniqueNames))(objectClass=groupOfNames))(objectClass=group))"
The cmdlet can also return all the attributes of each DN returned if I just specify the -attr flag in the get-ldap command.
