Description Ruben Romero Montes 2017-09-13 11:20:07 UTC
Description of problem:
Having a valid OpenShift user with a backslash in the username (e.g. test\user) generally coming from an ActiveDirectory is preventing the users from login in with the following error:

{"type":"log","@timestamp":"2017-09-13T10:55:48Z","tags":["status","plugin:elasticsearch@1.0.0","error"],"pid":15,"state":"red","message":"Status changed from green to red - [pattern_syntax_exception] Illegal Unicode escape sequence near index 6\ntest\\user\n      ^","prevState":"green","prevMsg":"Kibana index ready"}

Version-Release number of selected component (if applicable):
  Also reproduced in

How reproducible:

Steps to Reproduce: (no need to synchronize with AD)
1. htpasswd /etc/origin/master/htpasswd test\user -p test
2. Log in to Openshift with this user
3. Create a project with some demo pod running
4. Click "View Archive"

Actual results:
 Kibana GUI error (see snapshot)
 Kibana Logs: 
{"type":"log","@timestamp":"2017-09-13T10:55:48Z","tags":["status","plugin:elasticsearch@1.0.0","error"],"pid":15,"state":"red","message":"Status changed from green to red - [pattern_syntax_exception] Illegal Unicode escape sequence near index 6\ntest\\user\n      ^","prevState":"green","prevMsg":"Kibana index ready"}

Expected results:
 User can view the logs normally in Kibana

Is this a duplicate of 1456584?

Comment 3 Ruben Romero Montes 2017-09-13 14:35:05 UTC
It doesn't seem to be the same error. This one is:

 Illegal Unicode escape sequence near index 6

The other error was related to spaces in the names and the error message was: 
 com.floragunn.searchguard.tokeneval.MalformedConfigurationException: no bypass or execute filters at all

Comment 5 Jeff Cantrill 2017-09-13 15:19:58 UTC
I think the error message is unrelated to the login issue.

Request failed to _mget

The response is the following:
            "reason":"Illegal Unicode escape sequence near index 6\ntest\\user\n      ^"
      "reason":"Illegal Unicode escape sequence near index 6\ntest\\user\n      ^"

Comment 7 Ruben Romero Montes 2017-09-14 13:18:04 UTC
After that, when I refresh I am redirected to the status page with the following message for the elasticsearch plugin:

elasticsearch	1.0.0	 [pattern_syntax_exception] Illegal Unicode escape sequence near index 6 test\user ^

Comment 9 Jeff Cantrill 2017-09-14 20:19:08 UTC
The issue is in the SG plugin that is unable to handle user names with a slash.  Created: https://github.com/fabric8io/openshift-elasticsearch-plugin/pull/101 which converts the back slash to forward for ES use

Verified and pass on images v3.
