[cifs-discuss] Why can't we write to files created in multi-protocol setup?

[Afshin Salek]

You need to setup your ACLs and also identity mappings properly to
get the desired results in a multi-protocol environment.

Post the output of the following script so that we can take a look
at your configuration:

http://opensolaris.org/os/project/cifs-server/files/cifs-gendiag

Also provide a more specific example with user information from
both sides and also the ACL of the file being accessed. You can
get the ACL using "ls -V"

The opposite is also a problem in that CIFS created files can't always be written to from NFS. Sometimes the ! symbol to force the write works, but not always, and then we can usually never write to the file again from CIFS.
