isn't a big problem, but if you have run your kerberos realm for a few
years, changes are big that you have quite a few `junk' principals.

@subsection Converting a database
The database conversion is done with @samp{hprop}. Assuming that you
have the @samp{kadmin/hprop} key in the keytab @file{hprop.keytab}, you
can run this command to propagate the database to the machine called
@samp{slave-server} (which should be running a @samp{hpropd}).

hprop -4 -E -k hprop.keytab slave-server

@section Version 4 Kadmin
@samp{kadmind} can act as a version 4 kadmind, and you can do most
operations, but with some restrictions (since the version 4 kadmin
protocol is, lets say, very ad hoc.) One example is that it only passes
des keys when creating principals and changing passwords (modern kpasswd
clients do send the password, so it's possible to to password quality
checks). Because of this you can only create principals with des keys,
and you can't set any flags or do any other fancy stuff.
To get this to work, you have to create a @samp{changepw/kerberos}
principal (if you are converting a version 4 data you should have this
principal), and add it to the keytab the @samp{kadmind} is using. You
then have to add another entry to inetd (since version 4 uses port 751,
not 749).
@emph{And then there are a many more things you can do; more on this in
a later version of this manual. Until then, UTSL.}
