I appreciate that the decision on whether to canonicalise is not always
obvious and that you support overriding, but I believe that the reported
issue with the code still applies in the current version: that peerhost
returns a stringified IP address, not any form of actual hostname.
Given you've decided to retain the canonicalisation feature, it would
surely still be necessary to look up the name of the IP address.
Note that the current behaviour happens to work with MIT kerberos but
does not work with Heimdal.
