Problem with login.krb5 (NFS home dir problem)

[Someone]

Hello,

I am now using login.krb5 instead of login on my Linux Slackware 8 and 
my home directory is mounted via NFS like that:

/home/username 
		fileserver:/home/username

The problem is that when I log it I get the following error message:

No directory /home/username!
Logging in with home = "/".

This is very annoying, I have tested it only happens when my home 
directory is NFS mounted. How can I avoid that or fix that ?

Any help would be really appreciated

Many thanks

Regards
