Cyrus-SASL has one Lib, which is normally linked against the Application. This
is libsasl2.* (In your case it is in Postfix). The other Libs are loaded at
runtime. libsasl2 scans the Plugin-Directory (/usr/lib/sasl2) for the *.la
Files. In each File is a reference for the Library. This is the
dlname-Option. In your case it is empty, so sasl cannot load this Lib (and
others, too. I think.). Cyrus-SASL logs it to Postfix, but it is dropped.

Everything in your Cyrus-SASL seems to be static. You should rebuild it. And
next time dynamically ;-)

This is ok.

"external" (for the ssl/tls mechanism) is included in libsasl. plain is an
external plugin, which is loaded at runtime.
