Trac should share user account information with the OSI Drupal Page

[ernie.prabhakar]

Right now, the Trac and Drupal use and require two separate logins. If they could be unified, then it would be much simpler to manage user account requests.

There are PAM modules for both Drupal and Trac. This should let us unify authentication.

Using PAM means that we're tying web page accounts to system accounts on a one-to-one basis, which I'd like to avoid on this server for security reasons. Furthermore, these system accounts would have to be shared, probably using pam_ldap/nss_ldap, which means we would not be able to add/remove accounts in either web interface. I would rather suggest OpenID, a cross-web-site authentication mechanism. This means that accounts can still be controlled in each web backend, but users between the sites share account names and passwords.
