Why OAuth Workflow fails with 400 status code for an Owner account?

Anns 61

I have set up Oauth Flow in my application. I have 2 types of accounts for my Azure AD. One is an Owner account and the other is a Global Administrator(Sub user of the owner) account. My implementation works for the global administrator perfectly fine but fails with the Admin account. Why?

I flawlessly call APIs with the access token generated for the global administrator and everything works fine.
Is there any restriction or I am doing something wrong?

Hi @Anns

Can you share all the detailed steps you are doing? At what step did you encounter the 400 error? Is it when acquiring tokens? I need to know more contextual information to facilitate testing.

Yes, it happens when acquiring tokens.
