Onelogin SAML implementation with other IDP that accepts SAML

Question

Does the sample Onelogin SAML implementation, work with any other IDP that accepts SAML?

Answer 1

In theory, it should since SAML is a standard.

But an IDP does not have to implement every part of the standard e.g. they may not implement things like artefact resolution or IDPinitiated.

So that may stop it from working.
