POST binding support for authnrequest

[Fredthelead]

Added POST binding support for the SingleSignOnService endpoint

Is not that easy, what if you need to sign the AuthNrequest?

I don't gonna merge this since add complexity to the toolkit, but will leave the PR open in case someone needs this feature.

We also require POST binding. Would be very nice if this is merged in base branch!

@pitbulk FYI I've now added support for signed AuthNRequests over POST binding 🙂

@pitbulk It would be so great to be able to use this in the package itself. Is there any way to use POST binding with signed AuthNRequests? We would really need this, since there are IDPs who only support POST binding.

@Fredrik82 if there is no official way, what would be the easiest way to integrate this?

Did you actually find a workaround how to achieve this?

Did you actually find a workaround how to achieve this?

Yes. We implemented the endpoints by our own. Similar to how the pull request handles the logic.
But it looks like we are going to ditch this library in the near future, because the development of it is really slow - e.g. we have a pull request that is waiting for a release for months now :(

@joonlabs do you know any better alternative?

[joonlabs]

@jaulz not really yet. I am in contact with the guys behind https://github.com/simplesamlphp/saml2 - it looks promising but is not ready yet to be used as a replacement for my understanding
