Samba as PDC for XP pro client - Red Hat 9

If anyone can help me i would be glad.

I've configured my linux box with samba (RedHat 9 and samba 2.2.7) in order
to run as a PDC for my XP Pro client but it won't work.

In /var/log/samba/log.smbd i see this :

ignoring unknown parameter "login path"
ignoring unknown parameter "login drive"

I suppose this is why my XP client can't join the domain but every how-to
has both

login path = \\N%\profiles\%u
login drive = h:

What is my error ?

Thx.
