Authentication methods for Haskell web applications.
Note for Rpxnow: By default on some (all?) installs wget does not come with root certificates for SSL. If this is the case then Web.Authenticate.Rpxnow.authenticate will fail as wget cannot establish a secure connection to rpxnow's servers.
A simple *nix solution, if potentially insecure (man in the middle attacks as
you are downloading the certs) is to grab a copy of the certs extracted from
those that come with firefox, hosted by CURL at
http://curl.haxx.se/ca/cacert.pem , put them somewhere (for ex,
~/.wget/cacert.pem) and then edit your /.wgetrc to include:
ca_certificate=/.wget/cacert.pem
This should fix the problem.
