Ambari UI Login Issue user comes as null

Prv account part of AD group is not getting sync'd to Ambari and default access is not working.

2020-01-07T15:18:15.345Z, User(null), RemoteIp(10.176.18.143), Operation(User login), Roles(
), Status(Failed), Reason(Authentication required)
2020-01-07T15:18:15.346Z, User(null), RemoteIp(10.176.18.143), Operation(User login), Roles(

Normal lanid works fine and both are part of same AD group which has admin privileges.

the login is direct and not via knox , another weird thing noticed is prv works fine for knox login

@singm125

Which version of Ambari are you using ?

I see that there is a JIRA opened and addressed in Ambari 2.7.4 for addressing the "null" user appearing in "ambari-audit.log"

[JIRA] Ambari audit log shows "null" user when executing an API call : https://issues.apache.org/jira/browse/AMBARI-25234

@jsensharma - I have managed to resolve the issue for my case it was an issue with ambary ldap sync which I had to run with the existing option and that did the trick .

So this can be marked as closed now.
