    [* Sigh *] You _are_ confused.  Like OpenLDAP, Postfix doesn't
have its own SASL functions, it only has "hooks" for an external SASL
library, namely the one from Cyrus.  To compile Postfix (or OpenLDAP)
with SASL support, you need to tell it where to find Cyrus SASL.

    Nothing.  I was just recalling the context of the thread from
postfix-users.

    Yes, because Courier has its own SASL functions, it doesn't need an
external SASL library.  Unlike Postfix and OpenLDAP, you can't compile
Courier without SASL, which is why you don't have a knob to enable or
disable it at compile time (you can however disable SASL for POP3 at run
time).  You also don't need a *.conf file in /usr/lib/sasl2 (or wherever
it lives on your computer) as you would have had with Cyrus SASL, since
Courier automatically selects the mechanism to use.

    It does.  You just don't know that.
