I have set up the auth_external module according to directions on the silverstripe website, on a new installation of version 2.2.2. I have also applied the patch available at http://open.silverstripe.com/ticket/2536. However, when I try to log in to the silverstripe admin interface with the external authentication, it redirects me to a page http://localhost/silverstripe-v2.2.2/Security/?executeForm=LoginForm. This page is blank, and does not redirect further.

This error has occured on multiple installations of silverstripe, and when using both the sample _config.php available in the doc folder, and a custom-built _config.php. I am trying to authenticate via LDAP.

Is there a known issue with Silverstripe v2.2.2? I am using this code in a business environment, and need to be able to issue admins with their usernames quickly. This requires synchronization with the ActiveDirectory database, via LDAP. As far as I am aware auth_external is the only way to do this with silverstripe. I would hate to have to change CMSs just because of this.

Thanks!

I tried that as well, but it makes no difference. Anyone know what's going on?
