Hi, I have been struggling for weeks to get LDAP to work in Zeppelin now. Unfortunately for me, I cannot use websockets unless also using LDAP for authentication. So if I use the anonymous user, I just get a blank home page. Zeppelin leaves no configuration option to disable web sockets. My company has their own cert authority, which I have added to my trust store.
When I try logging in to Zeppelin using my LDAP, I get “SunCertPathBuilderException: unable to find valid certification path to requested target”. I have attached the full stack trace. Note that I am using ldaps over 636. Basically it’s like saying that my trust store does not identify my LDAP server as a trusted web server. I am certain that my JKS file is configured right, I have had a co-worker double check it for me. To troubleshoot, we did: Export JAVA_OPTS=’-Djavax.net.debug=all’ Now we are seeing all of the SSL verbose logs in the zeppelin--…..out file. I was surprised to see this: … keyStore is : keyStore type is : jks keyStore provider is : init keystore init keymanager of type SunX509 trustStore is: /application/jdk1.8.0_101/jre/lib/security/cacerts trustStore type is : jks trustStore provider is : init truststore … So it looks like the application is not truly using the trust store I have configured. I have this in my zeppelin-site.xml: <property> <name>zeppelin.ssl.truststore.path</name> <value>/application/zeppelin/conf/zeppelin-truststore.jks</value> <description>Path to truststore relative to Zeppelin configuration directory. Defaults to the keystore path</description> </property> It seems to me like the key and trust store are not getting used to connect to the LDAP server. Other factors: · I am using a corporate proxy · I have dockerized Zeppelin Unrelated comments: · Every time I want to test a change in Zeppelin, the NPMInstaller wastes a minute of my life trying to download some files. It fails every time, and it prints a stack trace in my logs every time. I would like to disable it, but I looked through your code, there is no way to do it. Your code also does not provide any opportunity to configure a proxy, so there is no chance this would work for me. I am even thinking of making a pull request to fix this, it’s quite annoying. I don’t know why the authors assume that other people are ok with this pattern. · I am also getting an exception in the logs stating: No operation matching request path "/api/login;JSESSIONID=92e79cbe-9113-473d-b76a-165666c3f221" is found. Is this a bug in Zeppelin? Does anybody know why this is not working? Or how I can fix it?
