Let me explain the use case: we are using SAML as authentication system, and we need to give specific users specific roles, there is no group information in the IdP that can be correctly mapped to the roles. The role attribution can be very specific and also on-demand. Because of that, we thought we could use the "mail" attribute to map roles, this way we could manually give the specific roles to the individual users, and it would work.
But now we also want that all other users trying to access Splunk would be able to sign on and automatically get a very limited default role with minimal permissions, without having to assign this limited role manually to each one of them.
We tried using the configuration:
defaultRoleIfMissing = my_limited_role
But random/unmapped users who tries to access Splunk gets the error "No valid splunk role found in local mapping." and can't sign on, so I was wondering if is was possible to do it in some way.
