You could model this in grouper permissions.
The people would be groups.
The servers would be resources (and can be hierarchical).
Do something with actions? Maybe the group name is the action? Or maybe
just use "assign"?
To get them into LDAP maybe have a loader job that reads the permissions and
sets up groups for you (then the pspng will take it from there). This could
run hourly or however often.
This would be pretty straightforward to setup if you need help let me know.

That'd be close.
Something tells me to add one level of indirection, though that may be
because I don't completely understand Grouper capabilities yet.
E.g. let's say I want to restrict ssh access to SIS servers to the set of
sysadmins. Somewhere in there I might want to model a group containing the
pool of servers which come and go over time, and another group of individuals
belonging to the sysadmin group, likewise who come and go.
Maybe the simple thing to do is forget the servers and simply push (CFEngine,
Puppet, ...) the "plussed" NIS group to /etc/password on subject servers with
making 'sysadmin' membership dynamic (say, Grouper-fed LDAP), and leave it at
that. Not pretty, but perhaps functional.
