Does a user HAVE to have an account?

[Austin Gonyou]

Must a user have an account on a workstation in order for them to be
able to login to that workstation, if it is told to authenticate with
kerberos as the primary mechanism?

I'm just curious, I've never 100% successfully setup kerberos, but never
had the time either. Now I've got the time, and I've got a test-bed
setup for this. Then I wondered about this question. 

TIA
