Absolutely not. Read the specs [0] there as well if you truly want to know. XML canonicalization is a special kind of hell that I've done once and wish to never do again. And the enveloped signatures of xmldsig are also pretty complicated to get right. And it's a wild west as to how the specs are implemented on RPs and IDPs alike (more so, in my experience, than OIDC by a long shot).

(I know, agreed. Rhetorical.)

SAML is much, much worse than OIDC.

No. I think SAML(/Shibboleth) was a big influence to OAuth2 (?) and is probably the source of most of what ails OAuth2.

Give it a try and try to come back with your sanity intact. I dare you :)

It's mess.

Having just updated a project to use a newer version of the OpenSAML libs, this x1000. How something so fundamental can be so badly implemented (and documented!) is just mind-blowing.
