Active Directory Ldap query to get all users of the same primary group of a user -

i need ldap query windows server 2012 ad starting username of user , getting collegues. in ad collegues ad identified same primary group. possibile or should need 2 step query?

thank you.

unfortunately, ldap filtering syntax not allow sub-queries within expression.

you'd have break 2 parts - first user's directoryentry record, use primarygroupid in separate filter, :

(&(objectclass=user)(samaccountname=jsmith)

now let's jsmith part of default "domain users" group (513) :

(&(objectcategory=person)(objectclass=user)(primarygroupid=513))

this return users share same primarygroupid.
