Using Apple-supplied SASLv2 libs with C headers and saslauthd built from
cyrus-sasl 2.1.20 distribution
saslauthd started with -a pam -n0; testsaslauthd runs fine
Built cyrus imapd 2.2.12 from source (hacking config* to treat
'Darwin' like 'Rhapsody' and
various C source files to skip sys/msg.h) with
./configure --with-pidfile=/var/run/cyrus/cyrus-master.pid \
--with-cyrus-user=cyrus --with-cyrus-group=mail \
--enable-listext --enable-gssapi \
--with-bdb=/usr/local/BerkeleyDB.4.3/ --with-openssl \
--with-perl=/usr/local/bin/perl --with-libwrap --without-snmp
and symlinked /usr/cyrus to /usr/local/cyrus.
Cyrus master running imaps, pop3s, sieve, and imap to 127.0.0.1.
Cyrus imapd working out of /var/imap; imapd.conf includes
still not actually delivering any mail to it. i mtest -t '' -u bailey
Built sendmail 8.3.14 from source with (among other things):
APPENDDEF(`conf_sendmail_LIBS', `-lssl -lcrypto')
smtptest -t '' -u bailey works fine.
I was able to run sendmail and saslauthd (with no incoming mail other
than the nightly cron job output) for about 3 days with no apparent
problems, then started cyrus daemons. About 12 hours later, the
problem struck again:

There's a little more info in the logs this time:
imapd.log continues to have checkpoint messages from cyrus for the ~6
hours between the symptoms appearing and the reboot. No messages in
secure.log or auth.log. In system log, I see messages from cyrus
about checkpointing up to the time of the hang only. This is
fiollowed by a block of garbage:
<key>NSTableView Sort Ordering NSNavOutlineColumnSettings.v1</key>
<key>NSWindow Frame NavigatorWindow</key>
<string>187 166 800 798 0 0 1280 1002 </string>
then the syslog startup message from the reboot.
secure.log has nothing from about 4 hours before the freeze until the
reboot, when I see
Apr 10 05:59:58 localhost com.apple.SecurityServer: Entering service
Apr 10 09:15:58 localhost com.apple.SecurityServer: Engine::authorize:
Rule::evalu\ate returned -60008 returning errAuthorizationInternal
and sure enough, after the reboot, the machine dropped into the
console from loginwindow. If I reboot again after copying the logs,
all is well.
(Actually, I initially saw two error messages, the first noting the
-60008 error, and the second from loginwindow stating that an
AuthorizationRef had no associated username. To my shock, both the
original and a copy (with a different inode) now have the back end of
the error partially overwritten with the "AuthorizationInternal" above
and then subsequent normal log messages.)
I'm still baffled about the cause of the problem, though now I'm
starting to wonder whether there's something up with the disk cache or
driver, given the scribbling of what looks like a prefs fragment into
the syslog, and the odd persistence of a bad AuthorizationRef across a
Does this make sense to anyone, or should I just trash the whole
system and reinstall from CD?
