> I do not know how wide spread this is but there is a security vulnerability in the TORQUE authorization between client and server when using the default authorization method. Using MUNGE closes this hole but we would like to add an additional, more universal secure authorization method.
There was a high risk security advisory from EGI-CSIRT, so it should be
pretty wide spread. Our security guys were pretty shocked when I
explained that any root on any machine (ignoring the ACL which we are
using of course) has full access to the server. :-D

Certificates are pretty useless for this case.

GSSAPI works great. We are using it in production for almost two years.
Machines that are in ACL can access torque without tickets, otherwise a
ticket is required. We also have ACL for allowed realms (two actually,
one for general commands and one for submit).
