nifi after login error "Unable to view the user interface. Contact the system administrator."

[#1]

Hi ,

I have successfully enabled ssl and ldap with nifi in hdp cluster through (integrating hdf components to hdp using mpack)

The Challenge i am facing is the authentication is success for nifiadmin and all users in ldap but receive this error once we are logged in "Unable to view the user interface. Contact the system administrator.".

Ranger has been enabled for authorization and i have created policies for complete access for nifiadmin user but still the issue remains.

Remove users.xml and authorizations.xml files from Nifi installation directory.

Then restart Nifi , the authorization will rebuild new versions of these files based on the current configuration in your authorizers.xml file.
