Samba 3.4.8 pdc and windows 7

[Berni Elbourn <berni@elbournb.fsnet.co.uk>]

Hi,

I have the current version from lenny-backports: 2:3.4.8~dfsg-2~bpo50+1, 
the client is windows 7 Ultimate.

logins and profiles and nelogon scripts all seemed to work back in Feb 
2010 using the instructions here:

http://wiki.samba.org/index.php/Windows7

However today it seems the machine trust is broken. Removing and 
re-adding the windows 7 client to the domain claims to succeed on the 
windows side but this error is logged in log.smbd:

[2010/09/09 11:19:17,  0] 
rpc_server/srv_netlog_nt.c:603(_netr_ServerAuthenticate3)
  _netr_ServerAuthenticate3: netlogon_creds_server_check failed. 
Rejecting auth request from client WINDOWS7 machine account WINDOWS7$

And logins fail like this:

WindowsXP domain PCs still work just fine with this configuration.

Is anyone else out there having any success with windows 7 on a debian 
samba pdc? What have I done wrong, please?

Thanks,

PS: Samba claim 3.5.4 is their stable now...is there any chance of a 
samba 3.5 backport?
