[Samba] Windows 2003 to join Samba PDC

[Christian]

Hello,
I just wanted confirmation that Windows 2003 server will not accept old
samba (pre 3.0.x) SID format :
- I tried to make a 2003 join a Samba 3.0.23d, upgraded from 2.x => failed
- Tried to join a Samba 3.0.23d out of the box => ok

Here is the SID format on "old" box :

S-1-5-352321536-3979850313-2462592245-811329360-513

On the new one :

S-1-5-21-3605046359-4294347824-417408769-513


Now it will really bother me to reinstall all the computers of my company
so that the 2003 server can join the domain.
Do you know a workaround to make 2003 accept the old format, like manually
entering the domain and machine SID ?

Thanks -

Charles
