Hi Ahyoung, Thanks for this guidance, that’s interesting regarding the browser cache.
I was able to fix this using the idea in this HCC post<https://community.hortonworks.com/questions/47007/zeppelin-06-chrome-not-displaying-login-element-wi.html#comment-47104>. Once I changed the zeppelin.server.addr value to the hostname to which the loopback address points in /etc/hosts, the behavior in Chrome is as expected when rendering the page. I have a tangential question regarding https://zeppelin.apache.org/docs/0.6.0/security/shiroauthentication.html (which appears very similar to the content in the SECURITY-README.md I cited), it doesn’t specify whether the following line should be commented or not with authentication enabled: /api/version = anon I think it would be clearer for the documentation to specify that one way or the other.

The Chrome browser screenshot image that you provided seems outdated version of Zeppelin UI. Have you run former version of Zeppelin in your Chrome browser(i.e. Zeppelin-0.5.6)? It seems like Chrome browser cache or something. Zeppelin UI changed in 0.6.0 ver since this PR<https://github.com/apache/zeppelin/pull/1013>. Please clean your browser cache first. Your Firefox browser shows Zeppelin-0.6.0 UI properly. Regarding Shiro authentication, could you check whether Zeppelin server started well or not with Zeppelin log file under ZEPPELIN_HOME/logs/ dir? And I would recommend you to refer this guide docs<https://zeppelin.apache.org/docs/0.6.0/security/shiroauthentication.html> :) Thanks, Ahyoung 2016년 7월 26일 (화) 오전 12:28, Samuel Lachterman <slachter...@hortonworks.com<mailto:slachter...@hortonworks.com>>님이 작성: Hello, I am using the 0.60 Zeppelin binaries and I have enabled authentication using the directions here<https://github.com/apache/zeppelin/blob/master/SECURITY-README.md>. In Firefox 41.0.1 (on OS X 10.11.5), I am seeing the expected behavior where users are required to login (the Login UI element renders in the upper right corner). However, in Chrome 51.0.2704, this Login button does not render and I see no way to log in. I also see the following message in the Developer Console: http://127.0.0.1:9995/api/login Failed to load resource: the server responded with a status of 500 (Server Error) Should this be logged as an issue?
