[Samba] WinXP not creating profile

[Lluís]

I have just installed a new samba PDC following
http://www.howtoforge.com/ubuntu-gutsy-samba-domaincontroller-p2

but my winXP clients don't save their profile. It is created a
directory /home/samba/profiles/USER with permission 700 but no file is
saved there. The computer I amb testing with was in the old samba PDC
saving the profile with no problem, so I suppose is a samba problem.

Any hint of what may I be missing?

My smb.conf seen by testparm is:
[global]
        workgroup = BARCELONES
        server string = %h server (Samba, Ubuntu)
