i want to create a OpenId login system like stackoverflow :) in drupal..By default, drupal doesn't offer this..is there any plugin that does this job?
EDIT:the user should ALSO be able to login with their yahoo, gmail, aol or blogger account..u guys can't understand my pro.. it's simple..i've openID enabled in my drupal 6. When i try to use my gmail or yahoo account, it doesn't login.
What should i do for that?
Yes, there's a module for that.
But you added a drupal-6 tag, which suggests you're using Drupal 6; OpenID has been a core part of Drupal 6 for >2 years - it's documented in the handbook.
There is now a module that uses the Javascript OpenID Selector to add a similar visual interface and makes OpenID on Drupal much easier to use, the module is called OpenID Selector.
OpenId already included in core in drupal 6, just enable it. For drupal5 you need to install appropriate module.
