Crowd2 1.8 plugin

[marathiboy]

Hello,

I am using crowd2 plugin, the SSO part is working as well, however, the
server is very slow. Each page take about 30 seconds to load. I can see that
Jenkins is making way too many requests to crowd server.

Is there any setting that I am missing?

I also saw similar issue
http://jenkins-ci.361315.n4.nabble.com/JIRA-JENKINS-16703-Too-many-periodic-requests-to-Crowd-server-td4654843.html

and not sure how it was resolved. The ticket states that as of April 15,
there was new update to plugin but plugin page states that the latest plugin
is 1.8 from Aug 2014

Thanks

S

Hi,

  For https://issues.jenkins-ci.org/browse/JENKINS-16703 there is a pull request with a fix implementing a cache mechanism

  We hope to integrate it correctly in the master branch soon

  There is a patch jar attached to the issue that various people are using in production.

Thanks BR,

I did install that patch as well as restarted, but didn’t see any noticeable performance difference. Without SSO, response is under 2 sec, with SSO, it is more like 25 sec ☹

I am using Jenkins 1.594, crowd 2.8, plugin 1.8 + patch

We do use ‘Project-based Matrix Authorization Strategy’ not sure that is causing the problem…

Thanks

Crowd2 plugin code is trash, initial author mapped SSO into remember me. I fully refactored it to work right and it works fine with username/password. I'm waiting @aheritier's help to fix SSO part. His PR with custom caching may be redundant because crowd-client provides built-in ehcache and i will prefer shift any problem to crowd-client authors.

If you want help, then feel free to help trace SSO auth routines in refactored code.

With the patched version you have some additional cache settings. They are deactivated by default for backward compatibility. 

Like Kanstantsin said a huge work was started to fix SSO issues and the cache will have to be backported in its current form or using its native ehcache integration if it is possible and allow end users to configure it. 

My patched version was developed in few hours when I met the same performance issue with 'recent' Jenkins versions which are providing a more dynamic UI but which in counter part test the user permissions more often. As far as I remember I used the same authorization strategy. 

Best regards

Thanks,

I did see those additional setting and set the time to max, and did see good improvement ☺

Thanks for update.

What is the current status of this plugin?
Would be great to have the refactoring merged and released with a new version.
I would be glad to help.
