FortiSASE for Contractors (Agentless ZTNA)

Hello,

I'm about to configure Agentless access to private applications through FortiSASE for contractors, however, I read that it's required to Enable SSO authentication for SWG users, which needs an integration with user database such as Azure AD, without that Agenteless ZTNA cannot be configured (as I understand it right now).

I already enabled SWG, created the SWG policies required, and have a local user group created, but this SWG SSO authentication is making things though.

Is there any way to bypass this and use only the local database (fortisase database, coupled with MFA, why not). Or it works just like that and there is now way to do it differently ?

Thank you in advance
