Thanks Dmitry!

Originally I couldn't find any hooks that are executed before the user 
is authenticated. After tracing the execution of the FE scripts I 
managed to find one ['tslib/class.tslib_fe.php']['connectToDB']. My 
purpose has nothing to do with databases, but it serves fine just 
because all I need to do is modify the $_POST var. Its a bit hacky but 
it works :-)
