Set up Casdoor as SAML IdP for Office 365 / Azure AD RelayState parsing issue

Hello all, i'm looking for some assistance with setting up Casdoor as an IDP for Office 365. Any assistance would be greatly appreciated.

see docs

Thanks for the response, the configuration in the docs is specific to setting up Azure AD as a provider to for authentication requests, I am looking to see if we can use Casdoor as the IDP for Office 365.

AAD is O365, its the same thing

Correct, but our use case is that we want to utilize Casdoor to perform the SAML assertions (AKA the IDP) for our users that are attempting to log into O365. The documentation available is for the use case where Azure AD is being used as the authentication source for users that are attempting to log into Casdoor.

can you provide the O365 auth integration docs?

If they provide such feature you claimed, they must have docs right?

@hsluoyz - Attached is the documentation from Microsoft regarding using an external IDP. - https://docs.azure.cn/en-us/entra/identity/hybrid/connect/how-to-connect-fed-saml-idp

@hsluoyz - So after some digging we found the issue; in the RelayState: estsredirect redirect Azure has an "&" in the value i.e. "RelayState: estsredirect=2&estsrequest=rQQIARAAjZNNiON0GMbb6UxnprhuXZdFxcMcRMQ1..." on the response the "&" and everything after it is gone. How do we submit a bug?
