Since Crowd Embedded was introduced in JIRA 4.3 making the full integration with LDAP possible. Some of our customers don't have any longer a need for Crowd.

Atlassian should consider providing a migration path allowing those users to achieve their goal.

Currently, this task can be only achieved by users with significant programming experience with help of APIs.

Feedback from customers in SAC

We are using Jira 4.1 with Crowd and as I prepare for the upgrade (and server move) I need to know if Crowd install will be necessary. I understand the LDAP functionality is now build into Jira so what shall I do?

or

How do I go about switching to non-Crowd use when I migrate? I have the standalone 4.3 version up on our new server and prefer to import my xml backup. However shouldn't I do something about LDAP integration before importing? The import will expect I am using Crowd still.
