I upgraded pmwiki to beta51, I had to upgrade userauth from 062 to 0.63
Thanks very much for your hint, I had exactly the same problem!  (might 
be because 0.63 uses new pmwiki-auth routine, instead of basicauth)

I mean, it's not necessary to use wiki_pw and assign it to authpw before 
calling pmwikiauth, but I can't see, why it should lead to an 
misfunction. I logged  the password $_POST['authpw']  in pmwikiauth and 
it's the "correct" value, the correct password in clear text!!!! (as in 
the other case too).

seems like a good amusement!  for me too.!!
I'm glad now, your propositon works (not everthing can be understood:-)

I will mention the problem on  cookbook/userauth.
I think, it would be usefull to correct the module too.
