10.5.6 Server OD for centralized authent

[jonbrown]

Hello all,
I am new to these forums but I have what may very well be a simple to extreemly complex question. I have set up my OSX Server it runs great got Mail, MySQL, OD (Master), Firewall, iCal Server, AFP, SMB, Web (for webmail) they are all running fine and everything is great.

Now at the organization that Im working for they want to implement the use of a single password system so 1 password for computer logins, email, & filesharing all to be reset every 3 months. I know you can do this with OD but heres the question.

Right now I can

1. Bind my computer to the server flawlessly.
2. Get the other login field at login prompt
3. I can login as long as I have specified a home folder on the server If i have not specified that the window shakes and I cant get in.
4. What they want is not to use the home folder on the server but rather to use the local home folder on each users account that they are using now but with the benefits of a single sign-on through the server.

I am not sure if this is even possible but I am out of ideas thanks for your help!

Jon
