These instructions worked awesome. And you were correct in where it failed.
This is my bt output:
Program received signal SIGSEGV, Segmentation fault.
0x4136bd08 in ?? ()
(gdb) bt

Obviously, my next question is, why does this work for Postfix then?
Doesn't seem to make much sense to me that it works for one thing and not
another. And this is really odd, I just got it to work once, but any more
:-/
I typically have:

Continuing.
But the time it worked, I had a line for "reading symbols from
/lib/security/pam_ldap". And in my /var/log/imapd.log, I have:
Jul 6 09:26:53 balthasar imapd[559]: pam_ldap: error trying to bind as user
"uid=cyradm,
ou=Admins, o=negativetwenty" (Invalid credentials)
Jul 6 09:27:06 balthasar imapd[559]: accepted connection
Jul 6 09:27:50 balthasar imapd[559]: login: localhost[127.0.0.1] cyradm plaintext
(I logged in wrong the first time.)
Whereas, I typically have:
Jul 6 09:48:47 balthasar master[470]: about to exec /usr/cyrus/bin/imapd
Jul 6 09:48:47 balthasar service-imap[470]: executed

Jul 6 09:48:49 balthasar master[454]: process 470 exited, signaled to death by 11
If I try to use "-m login"
Jul 6 09:49:06 balthasar master[473]: about to exec /usr/cyrus/bin/imapd
Jul 6 09:49:06 balthasar service-imap[473]: executed

Jul 6 09:49:08 balthasar imapd[473]: badlogin: localhost[127.0.0.1] PLAIN no
mechanism available
... And this if I try to use "-m plain"
And I am quite convinced from my ldap logs, that the bind is successful.
Which leads me to believe that somewhere along the lines, this success is
not being relayed to someone.
Please let me know what you think. Thanks again.
