My real problem with this RFE is that there is no indication on how you
are planning to acquire the user credentials.

For instance:
- - how are you going to acquire terminal information with just a uid/gid
pair?
- - how are you going to handle the case where there was no terminal?
- - what about when there was no terminal, but there were X resources
available? (kernelspace wouldn't know anything about this at all..)


Shouldn't this RFE also include some proposal for how you are going to
ensure that only a single uid ever attempts access to the automounted
directory as well? (if needed?)


The current work-around is to have the credentials supplied by the map
itself.
