Thank you very much for your reply.

How does your SSO handle duplicate userids? For example, if someone logs in through the SSO using their VBulletin username and the exact same username already exists in Joomla, but it is not them, does the SSO MASTER sync the Joomla password to match with the Vbulletin username's password so there is just one userid across both platforms or does the SSO just ignore the existing Joomla userid and create a new Joomla userid with the same name using the VBulletin password?
