Hi guys, I have a problem with Knox. I am using HDP 2.3.2 with Ambari 2.1.1. I connected Knox to LDAP/AD successfully. I get 403 Forbidden when I do not grant access via policies in Ranger or 401 Unauthorized when I provid invalid credentials. My user and group search base is specified only to one user and one group because of ldap sizelimit exceeded (I only want to test that it is working). I am pretty sure that it can be a permissions problem. Below I described my error. Please find enclosed full gateway.log. Thank you in advance gateway.txt When I try to run a command: curl -iku user:pass -X GET 'https://localhost:8443/gateway/default/webhdfs/v1/?op=LISTSTATUS' I got an error: ERROR hadoop.gateway (AbstractGatewayFilter.java:doFilter(66)) - Failed to execute filter: javax.servlet.ServletException: org.apache.shiro.subject.ExecutionException: java.security.PrivilegedActionException: java.io.IOException: Service connectivity error. 2016-06-03 11:33:30,070 ERROR hadoop.gateway (GatewayFilter.java:doFilter(135)) - Gateway processing failed: javax.servlet.ServletException: org.apache.shiro.subject.ExecutionException: java.security.PrivilegedActionException: java.io.IOException: Service connectivity error. at java.security.AccessController.doPrivileged(Native Method)
