I need to test SAML federation for a web application that is protected by an in-house SSO solution that can federate in SAML.
For testing purposes, I generally provision a Windows Server 2012 R2 server and configure ADDS and ADFS on it and then create a relying party trust to our web application's SSO solution (our SSO solution has a ACS URL which I use here)
Now, is there a SaaS based IDP that allows me to quickly configure a user store and SAML federation with my application. I just need to test the simple use case of user authenticating with his IDP credentials and the SAML assertion being posted to my ACS url.
I know there are many SaaS IDP solutions but need to know which one provides the simplest and least resistant path for my use case.
Any suggestions are appreciated.
There are a number and you want one that is quick to use, good documentation and (hopefully) free.
I have used Azure AD, Auth0 and Okta for this kind of thing.
Sadly, SAML configuration is never easy!
