Kerberos integration for Sun webconsole and ARCo
The Grid Engine Analysis and Reporting Console ("ARCo") is a webapp built on top of a Sun application server framework called "webconsole" or "SWC".
In this very interesting mailing list post, Dougal explains how his organization was able to configure the webconsole package to query PAM for user authentication information.
This is of value because PAM is often the point at which Linux systems are integrated with LDAP, Open Directory, Microsoft Active Directory and other centralized identity and authentication services.
If you know how to integrate PAM with whatever centralized identity service your organization uses, Dougal's post explains how to make Sun SWC query PAM.
