SAMLRequest is lost if first login attempt fails #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. POST a SAML 2.0 AuthnRequest to the IdP
2. Fail to log in on the first attempt
3. Correctly log in on the second attempt

Instead of continuing with the login sequence, this error shows:

KeyError at /idp/login/continue/

'SAMLRequest'

This affects the latest revision in the "google-apps" branch, and probably the 
trunk as well.

Here's the stack trace:

This still appears to be happening, after tag 0.1. Does Django reset the 
session after a failed login? It may also be Django-version-specific.

Fixed a while ago, but definitely by release 0.15.
