Hi, we're using Moodle 2.1 on IIS7 in the college. We've got all the LDAP authentication working except in 2 weird areas:
1. When an invalid user name or password is entered, it goes to a "500 - Internal server error" page and the url is <moodle site>/login/index.php?authldap_skipntlmsso=1 (in moodle 1.9, it would say 'invalid username or password').
2. Occasionally a user would not be able to login with their LDAP account, if they try again later, it would work. Or if we change their authentication method to manual account, it works. What could we do to fix this (even if it's a network traffic loading problem)?
Any help is much appreciated
