My apologies, and thank you for the reply. 1& 2) Currently, we are not using AD. However, it is an option we're considering once we move onto our own server as opposed to being hosted online. HTTP Passthrough is also currently not used.3) Our server is running Windows Server 2012R2. It has IIS roles, but we haven't yet installed PHP or SQL, but would be doing so per the requirements of osT.4) If we were to go down the road of using AD, then usernames could be an option, but not preferred.With all of that said- Our users are complaining of having too many services to log in to; too many usernames/passwords to remember.I am of the thought for them to deal with it, we're not asking that much. Unfortunately I do not have a say in that regard.However, if hosted locally, I am not concerned about authentication. I could allow users to submit a ticket without registration. I am being asked to disable the requirement of providing an email address, and am curious if I am able to disable that. Our users are already ignoring the email notifications, so the loss of the notification altogether would not be a loss to our users.
