Windows 2000 RCS 5.7 and Samba 2.0.7

[Dilip Patel]

Hi,

I'm testing Windows 2000 and RCS 5.7 software to see if everything works
properly and ran into this problem.  The problem being if I try checking out
a
a rcs file vi samba share that uses NFS (automount)  I get a error 'bad file
descriptor' from rcs.
However, if I check out the same file when the share is local to the machine
that samba is running
everything works fine (No NFS/automount). 

My test  systems are the following :

clients:
Windows NT with RCS 5.7  --- works
Windows 2000 SP1 with RCS 5.7  --- failed

Server:
Solaris 2.6 kernel patch 105181_09
Samba 2.0.7  compile with gcc version 2.8.1 using
./configure \
--prefix=/var/tmp/samba \
--with-automount \
--with-pam

I have run truss to see what was going on and I think with W2K I get and
error with the 
system call fcntl.

I have include the truss logs in zip format (sorry for the size):

truss.w2k_local, file is W2K SP1 using the local drive that samba is running
on [w2ktest]
truss.w2k_nfs, file is W2K SP1 using and NFS/automount and FAILS on fcntl (I
think, not sure). [w2knfs]

here are snippets from both files, around where I think the problem happens

Could you please have look at truss logs and provide me with some feed back.
Also if you need the complete truss logs let me know.

The man page on fcntl indicates that this call only works on some
filesystems,
but what I don't understand is why do things work with Windows NT 4.

Thank you very much,
Unix Admin, Dilip Patel

PS.
I also have the samba logs file with debug level 8 if you need them but the
files are 
pretty big.
