A cloud-based identity and access management service for securing user authentication and resource access
Thank you for posting this in Microsoft Q&A.
Based on the error message you provided, it appears that the user account '******@iditbenperlas78.onmicrosoft.com' from identity provider 'https://sts.windows.net/40cde9ca-33f0-4c59-bbe7-5f648ace9556/' does not exist in the 'idit ben perlas' tenant and cannot access the 'Portfolios' application ('f53895d3-095d-408f-8e93-8f94b391404e').
The 'Portfolios' application is a first-party application, and it seems that you are trying to access it but encountering an error. As mentioned in this document (https://learn.microsoft.com/en-us/troubleshoot/entra/entra-id/app-integration/error-code-aadsts50020-user-account-identity-provider-does-not-exist), this error can occur in different scenarios.
As you are using an enterprise application that requires user assignment, error AADSTS50020 can occur if the user is not on the list of allowed users who are assigned access to the application. Please check whether your account has been assigned access to the application.
If you are still facing the issue, please provide more details about the problem, such as the request you are sending when trying to access the application and how your application is configured. This will help us better understand the issue and provide more targeted assistance.
Hope this helps. Do let us know if you any further queries.
Thanks,
Navya.
