FreeBSD 9.0-RELEASE : saslauthd 2.1.25 coredumps at Sendmail TSL/AUTH

A

Ajira

While trying to set up SMTP AUTH with Sendmail on my freshly installed FreeBSD 9.0-RELEASE, I'm running into a problem: saslauthd 2.1.25 seems to core dump as soon as I try to authenticate using SMTP AUTH via Sendmail.

Sendmail has been recompiled with the following flags, to facilitate SMTP AUTH:
Code: 
# SASL (cyrus-sasl v2) sendmail build flags...
SENDMAIL_CFLAGS=-I/usr/local/include -DSASL=2
SENDMAIL_LDFLAGS=-L/usr/local/lib
SENDMAIL_LDADD=-lsasl2
# Adding to enable alternate port (smtps) for sendmail...
SENDMAIL_CFLAGS+= -D_FFR_SMTP_SSL
Running the Daemon in debug mode with [CMD=""]/usr/local/sbin/saslauthd -a pam -d[/CMD] reveals the follwing:
Code: 
saslauthd[20109] :main            : num_procs  : 5

Segmentation fault (core dumped)
As you can see, "testuser" authenticated just fine using testsaslauthd, yet the attempts using SMTP AUTH via Sendmail all resulted in child processes choking up, and eventually the whole Daemon core dumped. On FreeBSD 8.2-RELEASE this worked fine, yet on FreeBSD 9.0-RELEASE it doesn't. Does anyone have an idea? Any help would be greatly appreciated. :)
 
So, I had hoped to solve this problem by reverting to FreeBSD 8.2-RELEASE. Here's where it gets funny: I have the exact same problem on FreeBSD 8.2-RELEASE!

I've followed the steps described in http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/smtp-auth.html 1-on-1 to install and configure everything. saslauthd works fine when I test it with testsaslauthd but once I try to authenticate with sendmail, then saslauthd core-dumps.

Does anyone have any idea ? If needed I can provide a core-dump file.
 
I followed the instructions in the handbook but when I got to the point of recompiling sendmail, the contents of /usr/src is empty. This is true for my fresh install of 8.2 and 9.0. See steps copied from the handbook.

5.Recompile sendmail by executing the following commands:

Code: 
# cd /usr/src/lib/libsmutil
# make cleandir && make obj && make
# cd /usr/src/lib/libsm
# make cleandir && make obj && make
# cd /usr/src/usr.sbin/sendmail
# make cleandir && make obj && make && make install
