sasl: Where are the sql plugins?

[Florian Lindner <mailinglists@xgm.de>]

Hello,
I have just installed libsasl2-modules-sql and the dependencies and wonder why 
there are no sql plugins listed:

saslpluginviewer  | grep sql returns nothing. I want to use postfix for SMTP 
relay authentication, but without sasl daemon.

Thanks,

Florian
