I recently started a Systems Admin job where teamviewer is used pretty frequently here. Another admin recently left, and the concern is they still have access to all our systems due to how teamviewer works. I want to migrate the entire environment to domain authentication.

The documentation shows that setting up windows auth (domain) is easy, but I want to be sure that it is the only way to be authenticated with a teamviewer session here. I cannot yet find anything which explicitly says this.

We have licensing for teamviewer 5 and 6, I think. Right now we have 7 in the environment, but I think most are in a trial version, so I am likely to revert to 5 or 6.
