Hi,
AD has this exciting feature that it won't show you all the members of a
group if that group has more than 1500 members, see
http://ldapwiki.willeke.com/wiki/MaxValRange

If I would query AD for the member attribute would the driver use the
LDAP_SERVER_RANGE_OPTION_OID "control" to get all the members or would
it just return 1500 members?

Thanks
