Once you turn on the feature in the Meraki dashboard you see a new section called Access Manager, which has a button inside of it literally labeled "Integrate with Microsoft Entra ID". Obviously that's not a problem for our clients that use it, but if you had something like a Developer WLAN that you maybe wanted to authenticate with GitHub as an IdP, or AWS, etc. it wouldn't work. This is all confusing, though, because the documentation you linked specifically mentions that service like Entra ID can be used (as in not only Entra ID): "Identity and Security Integrations: Integrations with external products and services like Microsoft Entra ID etc. that provide identity, security and behavior context for a user or an endpoint connecting to the network. An administrator has the ability to include any identity or context information from these integrations as a part of matching criteria in the policy evaluation." And after enabling the button and entering the Access Manager section, you see another link that takes you to https://documentation.meraki.com/General_Administration/Cross-Platform_Content/Organization_End_Users, which further states (and even shows images as examples) that you can have a single or multiple IdPs, and that "Optionally, multiple IdP sources can be synced into a Meraki Organization, enabling the integration of end users from various IdP sources into one cohesive system. Organization Users can be accessed across the organization and utilized in any of the networks and Combined Dashboard Networks." and "Identity provider sources such as Microsoft Entra ID can be added to facilitate syncs between the IdP and Dashboard. The IdP sources store the information about the end users & groups. This information is synced and cached by Meraki Dashboard to be used across the organization. Once an IdP source has been configured in Meraki Dashboard it can be used for IdP Syncs. A single IdP source can be used, or multiple IdP sources can be used. " So, I'm now confused and curious to know whether this is just a wording oversight, a limitation while it's in early access mode, or if they were really dumb enough to limit SAML auth (an open standard) to only work with Microsoft Entra ID rather than allowing any provider that offers SAML to be usable.
