[Samba] Preference of local or domain profile

[Douglas Phillipson]

With Samba v3.x and WinXP, if there is a local profile on the users PC 
when the user logs on while hooked to a Samba DC, should the PC check 
for the DC profiles password prior to checking the local profiles 
password?  I have a client PC, originally with no local profile, the 
user logs in to the Samba domain, his profile is downloaded to the PC. 
I have his group policy set so it won't delete the profile when he logs 
out so he can remove his PC from the network and he can still use his 
domain account and password.  The problem comes in when his domain 
password is changed and he re-attaches his PC to the domain.  The PC 
appears to use the local profile rather than the domain for credentials. 
  I thought if there was a domain controller that the client PC should 
ALWAYS prefer the DC to a local profile.  This occurs as it should with 
a Windows AD domain, but not with the Samba domain.  Do I have some 
settings or policies set wrong?  I hope I've explained this correctly...

Thanks
