My configuration does not use any SASL features, though. Since I installed some SASL components for reasons unrelated to Exim, I see the following error messages in auth.log for every received message:

None of the strings "ldapdb_canonuser_plug_init", "_sasl_plugin_load" or
"sasl_plugin_load" appear in the current exim git head. While I've
not checked 4.94 release explicitly, I don't recognize them either.
I don't know why they've turned up in the exim binary.
I'd suggest taking the question to Debian bugs.
