It would seem so much more logical to 'automatically' treat all ldap-groups as email groups, and simply use: groupname@domain as an address.(because how I see it, the only way now is to use extensibleObject, and then add mail attributes to your ldap-groups. And extensibleObject is not a very nice solution...)
That way: no extensibleObject required... -- [email protected] https://inverse.ca/sogo/lists
