Problem Description
When configuring custom SSO or authenticator, the login or logout would be redirected to certain page. However in Bamboo the logout could not be redirected. It works well with JIRA.

Steps to replicate

1. Navigate to $BAMBOO-INSTALL/atlassian-bamboo/WEB-INF/classes/seraph-config.xml
2. Edit the param-value parameter to any page in Bamboo

               <param-name>logout.url</param-name>
               <param-value>/userLogout.action</param-value>
   

3. Restart Bamboo
4. Try to replicate the issue by logging in and notice that it won't be redirected
5. If it is configured in JIRA it will work fine
