I am not clear about this - only the <remove> method seems to be
documented.  Looking throught the source code, the only references to an
"unregister" method are for mod_groups and the transports.

I have not been able to find one.  You have to log the user in and issue
the commands.  Yes, this is less than ideal. :(

That worked for me - after logging in the user (jabber:iq:auth) and
sending the above fragment, the user spool file was modified.  The
<password/> section was removed along with some other parts.  Hoever the
file itself was not removed, and the zerok authentication information
remained.  This allowed me to continue to log in using zerok
authentication.  I'd call that a bug, but I am still trying to figure
out how it was meant to work.
