That indicates a mistake in your /etc/sasl2/slapd.conf, which should have:

Well, now I just feel like an idiot. :) That did move things along a
bit, though now I'm getting this error:

2012-01-26T13:48:28-08:00 ldapsandbox10-1-qa-sjc saslauthd[15889]:
do_auth         : auth failure: [user=chas@test.com] [service=ldap]
[realm=test.com] [mech=kerberos5] [reason=saslauthd internal error]

I'm guessing the problem here is that the realm should match my Kerberos
realm, which is called "KRBTEST", not test.com -- is this something that
needs to be fixed with an authz-regexp?
No, authz-regexp is to map a sasl dn to a real user account in your ldap

But your user is chas@test.com with a realm named test.com, your
userPassword should be {SASL}chas@KRBTEST

What the heck are you talking about? If the username is chas@test.com then that is what goes in the password:

  userpassword: {SASL}chas@test.com

If the realm is actually KRBTEST then the username should be chas@KRBTEST.

and also exists as a principal on your kerberos db ;)
