In the campus where this system is working, for more than 3 years,
they don't complain about it. Because is the only place in the
University where the homedir are stored in a network filesystem. I
wasn't working here when this system was designed, but I have been
told that GNOME in Solaris was incompatible with GNOME in Linux in the
same homedir. That's way there is 4 homedirs. I don't know if in the
present GNOME in Fedora, Debian, Gentoo, Mandrive, Solaris play nice
between them. Anyone have experience with it?

The LDAP have 4 fields with the diferents homedirs, no problem with it
in the campus, where I control the LDAP, AFS and the clients. A big
problem in the University where exists much more labs and OSs, and the
labs are managed outside of the administration of AFS/LDAP.

I have think about it, but I would like to know if anyone is using it,
and how are using it for anything diferent that bin dirs.

I believe that AFS volumes don't have ownership, authorization is only
regulated by ACLs and the three bits of read, write and execute.
