Opendistro version 1.11.0 - Kibana UI prompting for login before OpenDistro login page


We have installed Elasticsearch 7.9 with the Opendistro version 1.11.0. we observed that Kibana UI was prompting for the username and password like a dialog box as below and once credentials are provided, the OpenDistro login page is being loaded.

Can you help us here on how to overcome this and get only the OpenDistro login page?
