I have set up a delegated LDAP authentication agains the corporate LDAP and it behaves really strange.
- With my LDAP user everything is absolutely fine
- One guy can only log in with his old password (changed in LDAP several weeks ago)
- Another guy can log in once, subsequent attempts are rejected
Unfortunately I haven't managed to get any LDAP debug output in the logs. What I already did is setting the following logs to DEBUG:
log4j.logger.com.atlassian.jira.login.security
log4j.logger.com.atlassian.jira.login
log4j.logger.com.atlassian.jira.web.action.util.LDAPConfigurer
The only debug output I can now see in the logs is "Authentication FAILED" - saw this already at the UI 
Any Idea how I could get more output about the LDAP communication? I need to be sure that there is no issue at my JIRA configuration in order to open a ticket at our corporate LDAP.
