Typically means that the SSO identity (VulpeLab) is already linked to a different Invision Power Suite (IPS) user account, and you're trying to log in or register with that same SSO identity again.
Here’s how to troubleshoot and fix the issue:
Invision Power Suite (IPS) Database
If you know what you’re doing:
-
Find the
core_login_linkstable. -
Look for the record with your SSO
identifier(from VulpeLab/Authentik). -
Delete that record to "unlink" the SSO from the IPS account.
We have experienced this more than once and found this to be the best possible solution.
