I'm working with SAML access to an MSP portal environment using Azure as the idP. I've recently split out a single organization to use a second Meraki Dashboard enterprise application in Azure. (Separate roles for access to customers vs our own networks.)
This all works more or less fine, but there's one caveat that I'm concerned will eventually change and break. The SAML configuration for an enterprise application has an "Identifier (Entity ID)" field which must be unique across apps in the Azure tenancy. The Meraki Dashboard app comes preloaded with "dashboard.meraki.com".
To get around the unique conflict, I just created a bogus "xxxxx.dashboard.meraki.com" URL, and it works.
Can anyone confirm if this field is actually important, and if Meraki may one day validate it and break this configuration?
