Allow me to clarify: we are operating AD for a pool of Windows based
developers, and we are operating OD for a pool of OS X based developers.
Our executive's desire is to migrate all the OD clients to AD, an idea I
oppose. Everything is working just fine the way it is. In view of his
stated agenda I am gathering evidence that a) we don't need to change and b)
if we do change we should use OD.
He's asked the goofy question, "If you could build from the ground up, which
would you choose?" as if we could ignore the current reality. The fact that
he posed such a worthless question and answered it with "because it's
mainstream", I am at a loss on how to agrue for preserving the current state
of our shop, especially since I am not an expert at this and there is an
obvious agenda to change to Windows. He hasn't justified it to me.
To answer his question: I would choose Redhat. Both Apple and Microsoft
have a pile of features beyond what LDAP provides. I like the idea of OD on
Apple's hardware, but I don't like that I cannot create a virtual guest of
OS X. I'm not convinced that the extra features of AD get us anything in
the marketplace, which surely is my executive's unspoken argument. He can't
possibly justify spending money to our CEO with "it's mainstream".
I can't find performance data on AD, OD or anything else. Does this whole
thing really boil down to such reduced opinions like "ease of use" versus
