Yes, I do have set KDC to be in kaserver emulation, actually I'm not sure
if I need to... :( Passwords are in heimdal database and as long as user
get AFS tokens I'm find with removing that option. Explanation?

OK, this I guessed I don't need. Could the docs be written more for
dummies? ;)

OK, so on Heimdal slaves should run kdc without any special arguments?

That was my impression, but I did not generate any /var/heimdal/m-key on
machines acting as slaves ... I did not have to do this step to start
hpropd ... so is the database unencrypted? The web documentation(URL below)
doesn't say anything about generating another master key (this time on slaves).

What a pity. I never got user to use info(1) program, I prefer html
although you say "bad html rendition". ;)
