[Samba] I/O error when trying to write

My setup is fairly straight forward; I have a Solaris 10 (SPARC) being used
as a samba server with AD sign on.  Users can log in fine and map their
directories through windows clients.  All the user home dirs and critical
project dirs are on a NetAPP filer.


When user tries to write a file, it is erroring out with I/O error, file
access is permitted for read operations only.  Investigating the problem
shows that on Solaris this message is appearing "NFS compound failed for
server filer.example.com: error 2 (RPC: Can't decode result)".   


It appears there is a problem with NFS v4 support either on the Solaris or
the NetAPP filer.  I've not had a chance to set NetAPP filer not to use NFS
V4; I'm attempting it this weekend along with hacking /etc/default/nfs .
Anything that I should look out also on the Samba side, especially the
ACLs/permissions issues related stuff?
