Have a working AD and ldapsearch works from Linux node to AD machine. Trying to setup Ambari to integrate with AD using LDAP with SSl set to 'true' and getting an SSL error. See below.

I was able to resolve my issue by going into Active Directory and changing all the user's password policy from "User must change password at next logon" to "Password never expires". Now all users are able to login to Ambari.

This may help. Status code 403 responses are the result of the web server being configured to deny access, for some reason, to the requested resource by the client.

hello Neerraj,
i'm looking for integrating LDAP server with hortonworks sandbox Ambari (HDP 2.5) and ambari-server --version 2.4.0.0-1225 i have tried twice to run "ambari-server setup-ldap" and "ambari-server sync-ldap –all" twice, but i'm keeping having error 403 at the beginning of LDAP Sync. when this error come up, i'm not able anymore to logging into Ambari UI with my Ambari credentials (admin/password). even after reseting my password with "ambari-admin-password-reset". but what i've observed so far is that i could in logging with "maria_dev/maria_dev" credential and also with some new user i have added during LDAP setup server. i was wondering if this could be a password migration tools that is doing the wrong password migration? i have checked the user "admin" in my LDAP database, and i can observe that it's not encrypted in the same way as user like maria_dev or raj_ops!! (see below): can this cause trouble during my ambari-server and LDAP synchronization? or it is due to my ambari-server LDAP setup settings?

I was able to sync the LDAP users to Ambari but all of the ldap users are not able to login to Ambari UI. admin/admin local account no longer can login as well. Getting 403 Forbidden errors.

Do you have admin user in AD?

If the admin user is synchronized from AD, then you will have to update the Ambari DB and update it. You should probably create a backup admin user with different name with Admin privileges in Ambari.
mysql> use ambaricustom
mysql> update users set ldap_user=0 where user_name='admin';

I tried logging in to mysql using the admin/admin account but won't let me in. Also tried root@hostname, same issue.
