MAAS itself doesn’t have built-in SAML configuration. The authentication goes through Candid, which can be set up to talk to your SSO provider. MAAS then uses Candid for login and RBAC for permissions.
If you need SAML, you should:
- Deploy a Candid service
- Configure Candid
- Point MAAS to use that Candid instance
The Candid community might be the best option to get that kind of documentation, find discussions or raise a question about SAML
