Hi Eduardo,

Sorry to hear you are having this error.  However the way you described this problem sounds very similar to a known bug in JIRA 7.2.0  through 7.2.5 that could cause this same behavior.   Please see JRASERVER-63109 for details.

If you are running a version of JIRA in that range, I would strongly recommend that you upgrade JIRA to a newer version such as 7.2.9 in order to resolve this issue.

There is a work-around on that bug page, but I can tell you that the steps to complete that work-around are not trivial to do, especially if you have a lot of users.  And honestly, I think that upgrading JIRA is preferable to having to rename all the users in your user directory twice.

Please let me know if you have any follow up concerns.


We have this issue, we are using


JIRA Software 7.3.6
