Dan,
You nailed it. Mere presence of sasldb plugin makes it work. The code doesn't look kosher to me though.
In sasl_server_new() there's a line: serverconn->sparams->canon_user = &_sasl_canon_user_lookup;
which unconditionally set canon_user callback to the function that performs both canonicalization and auxprop lookup. In case there's no auxprop plugins it results in SASL_NOMECH.
I guess it should check whether auxprop plugins are available in the system and either set it to _sasl_canon_user_lookup() or _sasl_canon_user().
Anyway installing sasldb plugin is easy enough workaround.
Thanks everybody,
Michael
