LDAP authentication stuck in forced password change loop

For a user with manual authentication - expire their password Enable password expiry here /admin/settings.php?section=authsettingmanual Let the user change their password so that the time of the recent password change is recorded. Use this SQL to speed up expiration: UPDATE mdl_user_preference SET value = <timestamp in deep past> WHERE name = 'auth_manual_passwordupdatetime' AND userid = <userid>; Log out and login again - verify you are prompted to change your password. Try and cancel the password change or go direct to any other page in moodle. Verify you are sent back to the password change form and cannot continue until you change your password. Install and enable php mod ldap Enable the ldap server authentication method. Set the ldap host to localhost Set the changepasswordurl to http://www.google.com Set auth_ldap | expiration to LDAP Change a users authentication method to ldap server authentication. Hack the ldap auth plugin a bit to make testing easier: (all changes in this file: auth/ldap/auth.php) 1. add "return true;" as the first line in user_login() 2. add "return ['username' => $username] ;" as the first line in get_userinfo() Verify you can login as this user using any password (hack confirmed!). Add "return -5;" as the first line in password_expire() Login as that ldap user again. Verify you are told your password has expired. Verify clicking cancel takes you to the login page again. Login as that ldap user again. Verify you are told your password has expired. Verify manually typing a moodle url will send you back to the login page. Login as that ldap user again. Verify you are told your password has expired. Verify clicking on continue will take you to www.google.com (which will show an error about POST being invalid). Login as admin and reset the changepasswordurl to empty Set the "Use standard page for changing password" setting to "Yes" Logout and login as that ldap user again Verify you are told your password has expired. Verify clicking on continue will take you to the change password page
