Hi,

the first question would be obviously why you use id_provider=ldap and
not id_provider=ad?

If there is a reason for using id_provider=ldap the next question would
be which group membership scheme you want to use. You can use the same
group memberships AD is using but you can use group-memberships defined
the in the special services-for-unix LDAP attributes (the 'UNIX
Attributes' tab in older versions of AD's 'Users and Computers' tool).

bye,
Sumit
