I've got an existing JIRA setup (with lots of users) and I've set up a Crowd server that is using LDAP as its primary directory.
On the Crowd server, I've defined the required jira-administrators, jira-developers and jira-users groups, all containing my LDAP account. I've configured an application for JIRA on Crowd and set it to use the LDAP directory and only allow members in the group. Testing authentication there works.
On JIRA, I've added Crowd as a directory and tested authentication there.
However, when I try to log in with my Crowd credentials, I get the error listed in the Question field. Logins with JIRA local accounts continue to work.
