I have a QNAP TS-212 NAS with current version of firmware. I believe it can be used as a domain controller - for user authentication. I can't work out how to do this.
If you have experience doing this with a QNAP NAS I'd be interested to know how you configured it.
Please don't tell me this is not a good idea. I already know the pro's and con's. I just want to set it up in my home/office and see how it works.
