In all cases I have courier (and postfix) use pam.  I have pam
configured to test the local unix database and if that fails to then
try LDAP.  For SASL, though, I'm only using the PLAIN or LOGIN methods
as both postfix and courier are setup to either only do SSL or only
accept a login after a STARTTLS.

From /etc/pam.d/smtp:
   auth        required      /lib/security/pam_env.so
   auth        sufficient    /lib/security/pam_unix.so likeauth nullok
   auth        sufficient    /lib/security/pam_ldap.so use_first_pass
   auth        required      /lib/security/pam_deny.so

   account     sufficient    /lib/security/pam_unix.so
   account     [default=ok user_unknown=ignore service_err=ignore system_err=ignore] /lib/security/pam_ldap.so

   password    required      /lib/security/pam_deny.so
   password    sufficient    /lib/security/pam_unix.so nullok use_authtok md5 shado
   password    sufficient    /lib/security/pam_ldap.so use_authtok
   password    required      /lib/security/pam_deny.so

   session     required      /lib/security/pam_limits.so
   session     required      /lib/security/pam_unix.so
   session     optional      /lib/security/pam_ldap.so
