You are probably referring to this paragraph (quotation from
'cyrus-sasl-2.1.25/doc/options.html'), regarding the
use of the ldapdb plugin:

When I was debugging the problem I described, I found that the measure
described above did not stop ldapdb from being loaded. It only seems to
avoid _use_ of the ldapdb plugin, which is still loaded along with all
other plugins present, and that was what caused the problem.
Now, if ldapdb is incompatible with slapd at a fundamental level, and
causes problems when loaded, I think not to load it is the right thing
to do, and this is what my patch does.
