hi Kwadwo Obeng, let me replicate the issue, i'll get back to you asap. Thanks and Regard Mohit Mali.

hi Kwadwo Obeng, Please follow the step to revert the changes. 1. Try to connect gluu-server backend with any ldap browser(jxplorer or apache ldap browser). 2. After connecting to backend go to gluu configuration. 3. Change the value of oxAuthentication and oxTrustAuthentication method to simple_password_auth. 4. Now disable the current oxIDPAuthentication (which is your ldap authentication you've set)by setting enabled value to false. 5. Restart the Gluu-server. 6. when the server is restarted, Try to login with default admin user and password. Thanks and Regards Mohit Mali.

Also, make sure that the admin user from AD is in the "Manager" group in the Gluu LDAP server. In a pinch, you can do this writing an ldif and using `/opt/opedj/bin/ldapmodify` Non sequitur, but make sure that oxTrust is not Internet facing when you go into production.
