Well, remember, NFS is a relatively insecure method. If AFP is failing, its probably due to authentication.
Pretty much, here's how this all should look:
- OD Master has proper forward and reverse DNS lookup
- WGM has proper AFP URL/path for each user
- WGM has LDAP record for home directories mount
- AFP server is part of the OD domain
- Kerberos is able to work for authenticating to the AFP server, which is supplied from the OD Master domain
Things to look at:
Share out a folder named Home with the individual user share points in it as opposed to creating a different share point for each user.
Make sure you have proper DNS for each server, forward and reverse.
Make sure Kerberos is working.
Check home folder URLs in WGM.
Check LDAP data from a client with dscl.
Hope this helps get you back on track.
