Hi, When I define a principal in my site.zcml and have it use the SSHAPasswordManager, I cannot login as a "TypeError: character mapping must return integer, None or unicode" is raised in the checkPassword() methid. It took me quite a while to figure out what was going on... The site.zcml contains the encoded password for the principal that will be "contained" in the global principalregistry. When trying to login, the encoded password is taken from the principal object created from the information in site.zcml, and it makes sense that the encoded password will be an unicode string. However the checkPassword() method of the SSHAPasswordManager cannot handle unicode or, more specifically, it will call base64.urlsafe_b64decode() on it that cannot handle unicode strings (or at least not in this case). I my assesment is correct, then I must conclude no one is using the SSHAPasswordManager? But maybe there's something I don't understand about what is going wrong here... Anyway, I guess I could fix this by have the encoded password encoded to ascii first before passing it to uurlsafe_b64decode. I think this would be safe, as the encoded password would not contain non-ascii characters anyway, right? regards, jw
