Jira recently got upgraded using the Manual Upgrade procedure and was successfully except I could not log into JIRA anymore. Even newly created users cannot log in a dn I can view the users in the CWD_USER table. The client message is : "Sorry, an error occurred trying to log you in - please try again."
Previous jira had been connected to Crowd for authentication but we would not be using crowd for the updgraded Jira. In order to complete the manual upgrade process, I copied the osuser.xml file to jira classpath and thereafter commented out the crowd integration section, enabliing Jira integration for authentication only. This did not work. In the new JIRA installation I have not gone throught with integrating crowd with jira.
