Moodle LTI Integration

We installed WebWork and trying to connect our Moodle users with WebWork LTI integration. But we cannot authenticate our users from Moodle. WebWork does not create accounts automatically and always gives below error.  Any ideas about what was the problem? 


Your authentication failed. Please try again. Please speak with your instructor if you need help.

Course uses an external authentication system. You've authenticated through that system, but aren't allowed to log in to this course.

I found the solution. My Moodle configuration in external tool page was wrong. Because of this WebWork gives the "Your authentication failed." error. Thanks.
