Confluence: No authenticaton

[Lars Hadidi]

Since our last reboot, the confluence server is not authenticating users anymore. It isn't listed under Atliassian Tools on the other applications (JIRA, Bitbucket) either.

The server startup isn't ununual, the authentication is managed via Crowd.

Hello,

What are the logs saying? It's very hard to say what went wrong without checking the logs first. You should check both Confluence ant Crowd logs. If you have a local admin user on Confluence, you can try to login with that first and check Crowd integration.

For integration with other tools, you need to check Application Links configuration. For listing, you need to check Application Navigator configuration.

Regards.

Thanks for your quick reply,

going through the logs of the Confluence's tomcat shows several exceptions:

Regular occurence of

org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks The web application [ROOT] created a ThreadLocal with key of type [com.opensymphony.xwork.ActionContext.ActionContextThreadLocal] (value [com.opensymphony.xwork.ActionContext$ActionContextThreadLocal@379bbafd]) and a value of type [com.opensymphony.xwork.ActionContext] (value [com.opensymphony.xwork.ActionContext@22d1bbef]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

Few occurences of

There is/are 1 thread(s) in total that are monitored by this Valve and may be stuck.

Many occurences of

Hello,

For the first exception, which is a memory leak error, check out this question and answer. You probably need to increase memory for Confluence.

https://community.atlassian.com/t5/Confluence-questions/Confluence-don-t-start-after-reboot/qaq-p/1040142

For the second exception, which is a thread stuck error, check out this question and answer. Accepted answer could be what you are looking for, since it is the same error.

https://community.atlassian.com/t5/Confluence-questions/Confluence-hangs-when-logging-in/qaq-p/716137

For the third exception, which is a JDBC error, check out this documentation. It is the same error as yours:

https://confluence.atlassian.com/confkb/unable-to-start-due-to-net-sf-hibernate-exception-genericjdbcexception-cannot-open-connection-128843899.html

Last one, the warning is about certification. Something is probably wrong with your certification. You can try to renew it.

Regards.
