10.5.4 Server/10.3.9 Client user home mounting issue

Hi all, hopefully someone can help me out with this.

I’m the admin at a school running Leopard Server with Leopard, Tiger, and Panther clients. The server is running Open Directory and is the home for all user accounts.

Leopard and Tiger clients can log in fine. Panther clients begin to login, and between the visual acceptance of the password and actually showing the user’s desktop, something goes wrong. It informs me that the user cannot log in at this time because an error occurred, and that the home directory is on an AFP or SMB share.

It’s an AFP share, but I don’t understand why the Leopard and Tiger clients are kosher and the Panther ones are not.

Advice?

I’ve already tried turning Kerberos on/off, etc. I have also discovered that I can mount AFP volumes just fine if I log in locally and then connect to the user’s account manually via Go–>Connect to Server.

Thanks!
