Are you asking if Microsoft decided not to use groupofnames in favor of security groups or are you asking why they put groupofnames in the schema?
I can't speak to the former, but I'd say the latter is due to it being part of many other ldap schemas (RFC 2256 put defines it). Many other mailers do use groupofnames as their distribution lists, including Exchange 5.5 IIRC. Having that in there would be a good idea for that if for no other reason. It's an auxilliary class and is defined in RFC 2256 ICYGAF. I would guess that's how it got included, and the value-add of reusing security principals might have been too much to pass up. I'm guessing on that part though. Personally, I wouldn't use them for Exchange. I would for qmail or postfix or some other mailer that needed to use LDAP as it's directory, but not for Exchange. -ajm -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Monday, January 17, 2005 11:54 AM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] groupOfNames story Anyone know the story behind the groupOfNames class? At first blush it looks like Exchange was going to use that and then right turned into using normal group objectclass instead. Probably because they are security principals but groupOfNames still is in the schema... Is anyone using this? Has anyone seen it used? Can Exchange use it does anyone know? If so, that would be the answer to people complaining about DLs that get converted to Security Groups. Yes being lazy on that last there. I will probably check it out myself but easier to ask if someone is doing it. Oh if you need a snicker for the day, check out birthLocation and what class can have it as a valid attribute.
