Trying to bind a Lion Client (10.7.1) to a Leopard Server (10.5.8). Getting a connection failed to the directory server. (2100) error after they appear to talk for a few seconds!?!

Can Lion bind to Leopard? I haven't read that it can't.

If 10.5 and 10.7 were incompatible, Apple would quickly be eaten by angry customers. (Microsoft still has to keep AD somewhat compatible with MS-DOS...) – grawity Aug 18 '11 at 7:32
ok. that's what I thought. but I can't make 'em play nice! Problem probably on our end then… – Meltemi Aug 18 '11 at 18:32
still can't make it work! – Meltemi Aug 25 '11 at 0:42
Have you attempted to load a lion open directory schema into the Snow Leopard directory server? It could be as simple as making schema changes. I wouldn't be surprised that Apple isn't providing a neat script to upgrade things, but LDAP is LDAP and a port is a port - so you should be able to whip your Leopard directory into shape with enough time and effort. – bmike Oct 8 '11 at 14:40

Apple says to update Lion to 10.7.2 to fix this problem. It didn't work for me though.
