To see the plugin with pluginviewer, you'll need to create a config for it
under service name 'pluginviewer', with something specificed for the
ldapdb_uri parameter. E.g.:

~$ cat /usr/lib/sasl2/pluginviewer.conf | grep ldapdb_uri
ldapdb_uri: ldapi:///

/usr/lib/sasl2 is the default but may have been overridden by FreeBSD (with
the --with-configdir configure option).
