runtime error: undefined index: UserID

[knuckleizer]

Hi, 

I'm playing around with SAML and chose simplesamlphp for practice. At this point, when my SP sends an auth request, after authentication but before it redirects back to the SP, I get a runtime error. the stack trace is shown here:

http://fpaste.org/95252/78401111/

As a result of this, perhaps, I do not see the final POST back to the service provider (took some packet captures)

I'm using the packaged simplesamlphp in ubuntu 13.10 (since i've put so much effort into configuring it, I'd rather not upgrade if this is simply a misconfiguration).

Appreciate if anyone has any help to offer on this.

My problem turns out to be a misconfiguration. I had one digit missed for the IP address in the Assertion Consumer Service configured in simplesaml. The runtime error is just a notice, and does not affect the flow.
