LIGO does something like that. We use Grouper to manage groups of
users who should have access to one of our Linux clusters (we have 7
clusters world wide). If you are added to the group representing a
particular Linux cluster then your X.509 digital certificate subject
is added to an access control list that permits its use to
authenticate and login to the head node of the cluster (we use CILogon
for issuing the X.509 certificates after authenticating via our
InCommon IdP and the "grid-enabled" OpenSSH client and server).

Provisioning of accounts is handled out of band--we are not ready yet
to deploy automated provisioning of Linux cluster accounts.
