[Samba] Problems with Dfs

[Greg]

I have two problems with Dfs that I'm trying to resolve.  I'm using 
samba-2.2.8ap-1 for Dfs and all links point to netapp filer shares.

1.  Files not present

When a user runs a script, he gets file not found.  The script must 
access the root of the share, then it can access the file.  It is not 
consistent.

For example
dir \\server\dfs\projects\test\test.txt
-> file not found
dir \\server\dfs\projects\test
-> get listing
dir \\server\dfs\projects\test\test.txt
-> get listing

It seems to go away when using a MS 2003 server.

2.  Auth denied

Users coming from non-domain client machines get rejected by the mount 
destination on the netapp filer.  They auth against the samba server 
okay with security=domain, but are rejected by the mount destination 
file server.  It does work if they auth against the filer first, but 
that is not the way we want it to work.  Maybe Samba does not pass the 
credentials to the Dfs mount destination server with the domain 
preceding the username as in domain\username?  Or because the user is 
now mapped to a unix user account samba sends the unix information for 
the auth to the filer when it should be sending the windows auth 
information?

Thank-you,
Greg
