Description
The Refresh Token field does not populate after clicking the Authenticate With Azure AD button under System > Settings > System Communication > MDM Services in the Administration UI. This can occur if the client secret contains colons or question marks. For integration instructions refer to Microsoft InTune MDM Device Integration in the Fortinet Documentation Library.
Scope
Version: 8.5 and greater
Solution
Workaround: Review the secret for special characters (specifically colons or question marks). If they are present, generate a new secret. Repeat this process until a secret is generated without these special characters.
