I want to change the information on our Jira application when a user can´t access the account and then click the Can't access your account? link to look as your implementation shown below:

Information on page https://jira.atlassian.com/secure/ForgotLoginDetails.jspa

If you can't access JIRA, fill in this form and an email will be sent to you with the details to access your account again.

When entering the username and a user does not exist I receive this message "A reset password link has been sent to you via email. You can follow that link and select a new password. If the email does not arrive, please contact your JIRA administrators."

How do I configure my Jira application to generate the above message instead of the default "No user with that username exists."

Please get back to me as soon as possible.

Best Regards,
Joakim Gahm
