-----------------------------------------

             Summary: Ambari LDAP integration cannot handle LDAP directories with multiple entries for the same user
                 Key: AMBARI-15554
                 URL: https://issues.apache.org/jira/browse/AMBARI-15554
             Project: Ambari
          Issue Type: New Feature
          Components: ambari-server, ambari-web
    Affects Versions: 2.1.1
            Reporter: Sebastian Toader
            Assignee: Sebastian Toader
             Fix For: 2.4.0


*Problem:*
In case LDAP set up with multiple Domains which are joined into a Forrest with trusts between the different Domains  users may appear in different locations in  LDAP.

Since users who wants to access Ambari can be in any domain Ambari has to search the whole forrest, and as the users appearing in multiple domains are identical Ambari cannot filter out all but one of the user entries.

This leads to the following error message when they try to login to Ambari with one of the users that has multiple entries:

*Solution:*
If the LDAP search upon login to Ambari leads to multiple match user match due to the user appears in multiple domains show an error message to user prompting for providing domain as well to log-in. (e.g. _Login Failed: Please append your domain to your username and try again. Example: username@domain_)

When user provides domain information at login as well Ambari looks up the user in LDAP using different filter which is configurable. If this configuration is not set Ambari defaults to filter by _userPrincipalName_
