cyrus-imap-admin/cyrus-imap-dev should only use --with-auth=krb in their build scripts only with USE=krb4, not USE=kerberos. For kerberos V all you should use is --enable-gssapi and --with-auth=passwd, unless, for some reason, you're building in both krb4 and krb5 support, in which case I'm not sure what the best behavior is. Maybe --with-auth=krb and --enable-gssapi.
I haven't gotten around to fixing the cyrus-imap-{admin,dev) for these. Can you confirm that cyrus-imapd is working correctly? if so I'll do the same fixes in -admin and -dev. Thanks.
Any progress on trying cyrus-imapd, Bryon? I'd like to make sure it works there before pushing it out to -admin and -dev packages. Thanks.
fixed in 2.2.3.
