A user who is attempting to login with SSO via SAML may receive the error:

You cannot access this right now.

Your sign-in was successful but does not meet the criteria to access this resource.  For example, you might be signing in from a browser, app, or location that is restricted by your admin.

This indicates that they have successfully logged in to their identity server, but an Azure Conditional Access policy enforced by their network is blocking their access to the Pentana application.  The user should raise this error with their  IT team.
