Hello,
The story is we have a TEST instance which is a clone of Production site. For whatever of reasons, some students logged into this TEST site and did some work. We tried a couple of different things to prevent this from happening again, like changing the theme, etc. Right now, we only allow manual login to this site temporarily, which is not a permanent solution.
We are using SAML2 authentication.
We do need a group of people (like 40~50 people) to access the TEST instance regularly. The TEST instance got refreshed from Production from time to time. I am wondering what's the best and easy way to limit the access only to a small group of people.
Thanks.
