Assuming you have compiled your saslauthd against the openldap library, you
can use ldapsearch to simulate the binds, with debugging set - assuming
LDAP_DEBUG was enabled during openldap compile:

echo "TLS_CACERT /tmp/cert.pem" >> ~/.ldaprc

ldapsearch -d -1 -x -H ldaps://internal/ -D
CN=myuser,OU=Standard,OU=User_Accounts,DC=internal,DC=subsidiary,DC=bank -w
secret -b OU=Standard,OU=User_Accounts,DC=internal,DC=subsidiary,DC=bank
"(userPrincipal=myuser at" 

And then does saslauthd rebind using the user's DN and password? I'm not
