If the KDB keytab is selected by command line options, then kinit will
register the KDB keytab and open the database.  This permits an
administrator to obtain tickets as a user without knowing that user's
password.

As a result kinit links against libkadm5srv and libkdb5. Discussion is
ongoing about whether this is desirable or about whether two versions
of kinit are required.
