OpsManager fallback authentication

Hello team!

We are trying to set up the Ops Manager authentication, but the SAML did not work and now when I browse to Ops Manager it is using SAML, so I can’t access the tool to change that back to the local authentication.

How can I fallback to the local authentication? Looks like there is no config file that I could change it, so maybe it is stored in the database?

Thanks,
Diego
