HEADS UP
========
This module moves your standard log in page to login/direct/ and places at its
previous location (user/) a redirect to the configured OpenID Provider.
OpenID SSO
==========
OpenID based Simple Sign-On among trusted sites.
Add a trusted Drupal OpenID provider to a Drupal site. Users enjoy a simplified
sign on process between trusted sites.
Assumes that the OpenID Provider in place is a Drupal site with OpenID Provider
SSO module enabled.
Note: this module does not provide true *Single* Sign-On functionality but a
largely simplified sign on experience for webs of trusted sites. Hence the name
*Simple* Sign-On.
It is strongly recommended to install this module on a fresh Drupal site.
Installing it on a site with existing users (other than user 1) will lead to
undefined results.
