get_nt_acl failing

[Lata Singh]

I installed samba 2.2.2 version and found that unix files cannot be opened from NT 4.0 workstation.
Whenever I call open() on any file, it says permission denied.
I have a NT4.0 server acting as PDC. The domain consists of various nt 4.0 workstation and unix solaris 2.6 m/c.

The samba log says when trying to open a file
2002/03/11 20:43:50, 3] smbd/process.c:(667)
  switch message SMBnttrans (pid 16612)

Looks like some problem with acl. 
The same problem doesnot occur with the same setting in samba 2.0.7.
I downloaded binary of samba2.2.2 from samba.org for solaris 2.6.
Can anyone tell me why get_nt_acl() is failing and how to set it right.
Thanks,
