How to remove users from JIRA user list

[Victor Campbell]

We are using LDAP to synchronize our user list in JIRA with the 100 authorized users.  Someone wrote a faulty group filter, which added the entire company of 2000 employees to the list.  Even though the group filter is now fixed, the non-users remain on the list.  How do I remove the 1900 names from my user list?

Hi Victor, 

I believe that at this point you have two options:

1. Write a code to use JIRA API to bulk remove this users
   OR
2. Use JIRA Command Line Interface to remove this users

Here's a documentation to better guide you on those process: https://confluence.atlassian.com/display/CLOUDKB/Perform+a+mass+delete+of+users

Please let us know if this helps you.
