multiuser mount without initial mount credentials

multiuser mount without initial mount credentials

[Orion Poplawski]

Is there any possibility of removing the requirement to have an initial set of 
credentials when mounting a cifs filesystem as multiuser?  I'd like to have an 
automount driven multiuser configuration without the need to have a separate 
set of credentials just for mounting.  Could we imaging some way for the 
automount process to access a keyring stored credential for use in mounting?

One possibility would be to teach the kernel how to use an anonymous
logon (equivalent to what we do with sec=none) for the initial mount.
That would take a bit of reengineering but it's possible.

Also, if you pass credentials to the mount command then those
credentials will just be used for root access. e.g. something like this:

    sec=ntlmssp,username=foo,password=bar,multiuser

You probably don't want to put that in a mount command, but you could
use a credentials file (see mount.cifs(8)).
