[TYPO3-dev] howto session data during auth service

[Achim Gerber]

Hi All,

I am implementing at the moment a special auth method, where some eID
AJAX calles generate a image with a random keypad layout. The user is
using this keypad to enter the password. The eID function is storing the
keyboard layout in the session data.

Problem: the time my auth service is called in
t3lib_userAuth::checkAuthentication this session data is not loaded yet.
Therefore I can not decode the entered password.

Is there an easy way to load the session data without reproducing the
code of actually fetching the session data in the auth service?
