I will look into the pam_mount solution as workaround to limitations in
Respecting the client count, different comments were given in different
contexts. I never wanted to suggest that I could accept a solution that
cannot scale to multiple clients, only that management of credentials
across 50 or even 10 boxes is not among my current worries. To clarify
the way I have matters at this moment, I have one client on which I
would wish to make a multiuser mount. This client is a server
supporting remote logins. Other clients are directly accessing the
shared files through simple mounts made on the fly. These are true
clients (e.g. laptops and workstations) that have no need to support a
mount that is always available beginning at boot, or that enforces
ownership and permissions correctly for different users accessing the
