We are currenly using HDP 3.0.1 with ambari 2.7.1. I was trying to solve a connection issue on the zeppelin ui that give to some of the users a disconnected status while they are using the chrome browser...(curiously it seems to be working just fine with firefox ).
I am able to see on the zeppelin notebook logs the following message:
Exception in login:
org.apache.shiro.authc.AuthenticationException: Authentication token of type [class org.apache.zeppelin.realm.jwt.JWTAuthenticationToken] could not be authenticated by any configured realms. Please ensure that at least one realm can authenticate these tokens.
Also on the knox logs i have the following error message not sure if it is linked:
Shiro unable to login: javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090400, comment: AcceptSecurityContext error, data 52e, v1db1
