Lightico have identified the root cause for some users failing to authenticate using the AuthenticateUser v1.0 API. .

This issue will be corrected overnight during scheduled maintenance window for Lightico NA1 environment at 2am EST on 20-09-2022.

As an immediate workaround, if a user is found to be failing to authenticate via API, the user can resolve the issue by completing a reset password at the following link:

If the user has been locked, a Lightico user with admin rights can unlock and reset the password in the User Management page.

We will update on this issue again, once the corrective fix has been deployed.

If assistance is required, please reach out to our support at
