[OpenID] LDAP-to-OpenID gateway?

What I would really like is a drop-in php/perl/whatever set of scripts
to make an OpenID server that uses Apache authorization to verify the
identity of the user.

This would allow a completely transparent single-sign-on system for
those of us using Kerberos and mod_auth_kerb on apache, and it could
also be used to backend to an LDAP database with the apache LDAP auth

(For example, my desktop linux box uses kerberos to authenticate me to
log in.. I then have kerberos tickets. If I go to my local openid server
website, firefox knows how to delegate the kerberos credentials to the
apache on the openid server.. what is missing is the little bit of glue
to make a simple openid server using apache auth.)

Somone asked me why I work on this free (http://www.fsf.org/philosophy/)
software stuff and not get a real job. Charles Shultz had the best answer:

"Why do musicians compose symphonies and poets write poems? They do it
because life wouldn't have any meaning for them if they didn't. That's why
I draw cartoons. It's my life." -- Charles Shultz
