Symptoms
After implementing Crowd integration, users cannot log into JIRA. The following appears in the atlassian-jira.log:
org.codehaus.xfire.XFireRuntimeException: Server returned error code = 503 for URI : https://<crowd_domain>/crowd/services/SecurityServer
Cause
The problem occurs because JIRA needs to generate a backend request to access the Crowd service on server side. The above error gets thrown when from one of the following:
The domain name of Crowd service can't be detected on JIRA server.
The JVM "-Dhttp.proxyHost" blocks the JIRA self-generated requests access to the Crowd service.
Resolution
Make sure that the domain of Crowd service can be detected on JIRA server. If it cannot, check the following:
DNS is configured correctly.
The hosts file is configured correctly.
Apply the IP Address instead of proxy name in the Crowd service URL.
