If this works as advertised, it will be incredibly useful.
Honeytokens are going to become a necessity for enterprises using AD. Which is basically everyone. (Cue howling from the 1% that "Never let the Beast of Redmond loose on their iron." News flash: You're an almost insignificant minority. Active Directory is pretty much ubiquitous.)
For example, in recent versions the telltale signature of Mimikatz has been removed so that, without honeytokens or behavioural analytics, this kind of credential theft is very hard to detect.
Definitely one to examine and, if it works well, this could become an essential part of the AD security toolbox.
