Cross-site login
Johnubis - October 12, 2009 - 03:53
I am looking for a module that will allow users to login in another drupal site using their login credentials that already exist on my main drupal site.
It would be even better if I could redirect users to the other site/server and them being logged in automatically.

Shared Sign-On
Shared Sign-On - http://drupal.org/project/singlesignon. I haven't used this but it is the basic module for the kind of functionality you're looking for.
=-=
The above module and its releases were removed for security reasons. The successor = http://drupal.org/project/sso
Oops
Thanks VeryMisunderstood.
I just tried SSO but it
I just tried SSO but it appears to be designed for multisite configs with both sites on the same server. The setup I have are two completely different drupal sites in different locations. SSO has potential but its backend is the database server itself. My hosting on the main site doesn't leave the mysql port for me to even work with this module by modifying it.
Is there anything else that can be recommended?
Shibboleth?
I just came across the Shibboleth Authentication module (http://drupal.org/project/shib_auth) due to a security warning (don't worry this one is fixed in the most recent version). It looks like Shibboleth (http://shibboleth.internet2.edu/) might allow for the kind of functionality you're looking for
but I didn't look into it in any detail.
