Didn’t test. But normally in a form authentication you use the from data to validate it instead. Why do you want to access the session there?

If you want to create a session from an authentication form, you can do the validation in the form.validate like that, and then do something like this:

To generate a session from from the principal

In the youkube sample there is another example of this:
