Controlling access to workstations

[Henk Mos]

In our department we are using a server (DECsystem 5500, Ultix 4.1) en a number
of client DECstations. Passwd en group files are distributed through yp. Every
research group has its own group entry. I'm looking for a simple to maintain
mechanism to assign workstation access (login, rsh, etc.) to one or more groups
and/or users, but to continue the usage of yp. I'm sure this has been done
before so any practical solution is welcome.

Thanks in advance,

Henk Mos
