[Samba] Slow domain logons with samba PDC

[David BENTO]

Just for information,

it was due to a problem with Lotus notes single logon, i had to modify winXp 
registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\Order and 
to clean the entry and now everything works normally.
