Knox SSO to HDFSUI failing

[#1]

Configured Knoxsso without Ambari. Knoxsso is configured with Shiro provider and updated the core-site.xml with below configs

• hadoop.http.authentication.type
• hadoop.http.authentication.authentication.provider.url
• hadoop.http.authentication.public.key.pem

Followed: https://knox.apache.org/books/knox-1-6-0/user-guide.html#KnoxSSO+Setup+and+Configuration

After restart, NN UI is redirecting to KnoxSSO and after entering the AD credentials it is throwing below error in the UI. The redirect to originalUrl looks valid from Knoxsso url.

ERROR Invalid Redirect: Possible Phishing Attempt

Any help is appreciated!

[#2]

I was able to resolve the "Invalid redirect" by adding knoxsso.redirect.whitelist.regex but when I enter AD credentials in the KnoxSSO page it keeps redirecting to the same login page.

I could see below msgs in gateway.log

Hello @Hadoop16  Can you disable debug logs and share the information logs from the gateway log file by replicating the issue

Hello @Scharan 

From the debug log I think the issue is when Knoxsso is redirecting to NN UI, it is sending user as anonymous. 
AclsAuthorizationFilter.java:enforceAclAuthorizationPolicy(133)) - PrimaryPrincipal: anonymous

Do you know what configs at hdfs or Knox could help here?
