Hi all, I have one question regarding filter string, (&(objectClass=Person)(|(sn=Jensen)(cn=Babs J*))) (&(|(sn=Jensen)(cn=Babs J*))(objectClass=Person)) (&(|(sn=jensen)(objectClass=Person))(|(sn=Jensen)(cn=Babs J*))) Which one from the above is valid? The first one? first and second? or all three are valid? Thanks for your time. Rosdi.
