Good shout.

Kerberos is an example of something that just works but is not for the lazy. It was clearly designed by Engineers and not Kool Kidz. The infrastructure required to make it work is not completely trivial but it is free in nearly all senses of the word.

If you can't be arsed to get clocks in sync and DNS to work properly then this is not for you but then neither is any sort of reasonably useful IT related stuff.

Kerberos is a mythical Greek dog and Dramatis Personae is a Latin phrase adopted by theatre and the main text is in English. The canonical justification text (cited above) is clearly an Engineer's work.
