[Samba] samba 2.2.5 unable to validate sid.

[Mead, Tom]

I am still having the following problem with samba 2.2.X - i have tried all
release's up to the latest 2.2.5 and reported the problem each time i try a
new release. I am running Solaris 8 server, windows 2000 SP2 (and NT4 as
well). 
To recap on the problem - i have a NT application installed onto the Solaris
server in an area that is mapped to a network drive on the Windows 2000
workstation. When i try to start the application it tries to read a file
(.root.passwords) on the server and fails - despite the fact that i can view
the file using notepad from the same workstation with no problems.
I am not using winbindd, the SID that samba says it cannot validate in the
log (S-1-5-21-1456024563-1430335328-122644288-2355) is that of the NT domain
user logged into the Windows 2000 workstation - the actual machine sid is
(S-1-5-21-871312468-273679825-1712333365). Please see log extract and
smb.conf below.
All of this used to work perfectly with Samba 2.0.X with Solaris 2.6 and
NT4.

Your probably all bored of hearing about this problem - but its a real pain
is the neck for me.

Thanks
