I installed the KickApps SSO and it would create accounts just fine when you create a Joomla Account. However, the Single Sign On does not work. I contacted KickApps support and after three days I got the following reply:

"We're willing to provide custom SSO integration support at the following rates: $500 for initial 3 hours support. $200/hr after."

Essentially, SSO is made available in an unsupported self-serve way.
