[Samba] unable to access restriced share with XP

[Paul Muad`dib]

Hello all,

I set up a samba server 2.2.5, locally all went fine, but when I try to
access a restriced share (valid users = xxx) with a XP machine
(security=share), the username is greyed and set by default to Guest.
Anybody else had this problem or any suggestions ?

Thnx in advance.

Paul
