Before we converted over from Track-It, we had recently upgraded to Track-It 7.0, which had several new addon features available. One of those features was a domain password reset option that allowed somebody to reset their own domain password (or perhaps unlock their account) by logging into to the web interface on, say, a neighbor's PC, and answering one or two security questions to identify the user. Something like this would be a very useful feature in SD+, as sometimes we get several password reset or account unlock requests per day.
Allowing users to reset their own passwords could allow technicians to spend time on more important projects instead. This is not a high-priority feature request, just something to consider for the future. Perhaps this could be considered after the single sign-on feature is implemented.
