How to delete 10000 users in bulk?

Question

Earlier JIRA Administrator wrote a script to add all users in LDAP to JIRA. 29000 users have been added to the JIRA instance. Now I found that there are only 2000 users are required and rest 27000 users are not at all relavant. How do i delete the 27000 users from JIRA.

Do you have any automation, python script or any other mechanism?

JIRA Command Line Interface has actions for adding and removing users. These can be used in combination with runFromSql action to drive the automation from some database select statement.
