I have a running instance of JIRA 4.2 with integrated SSO, and we are in process of upgrading JIRA to 5.2. When i setup the SSO integration aby put and modify all the related files, it redirects perfectly on SSO url but come back to JIRA showing some error like "java.lang.AbstractMethodError". I have attached a error of above error.
Cause:
java.lang.AbstractMethodError: com.atlassian.configurable.SMAunthenticator.getUser(Ljava/lang/String;)Ljava/security/Principal;
Stack Trace: [hide]
