[Observium] http-auth

I configured observium to use the http-auth method combined with our web sso system. I believe it is OpenAM, but I’m a consumer of the service and not someone who maintains it.

I’m mentioning this because the docs state there are no known users of http-auth. It works well, and required no configuration on my part. I just have to create users for each person that match their campus NetIDs.

This is incredibly useful.
