After integrating Crowd with JIRA, reports the error: An internal server error occurred when requesting resource

The following error is logged in atlassian-jira.log file,

010-10-19 10:07:41,971 http-8080-1 ERROR      [500ErrorPage.jsp] Exception caught in 500 page com/atlassian/seraph/auth/LoginReason

The issue is caused due to invalid seraph-config.xml configuration.


Find the following line:

        <authenticator class="com.atlassian.crowd.integration.seraph.v22.JIRAAuthenticator"/>

and change it to:

        <authenticator class="com.atlassian.crowd.integration.seraph.JIRAAuthenticator"/>
