Yes I am! :-) In fact, I DID all the above (with more or less variants), but I was wondering why the command testsaslauthd wouldn't allow me to test authentication. Now I don't care anymore - what I need it for is: "postfix with SASL AUTH agains smtp clients" and for THAT I only need a properly filled and protected (postfix will have to be able to read the file) /etc/sasldb2 file. I was also wondering because on the machine that I'm migrating away from the testsaslauthd command worked. Same config and both using the same centos release. Ok - nevermind, the authentication works, a nice thing to start a thursday with. Thanks @Alexander, Kai and Nataraj and all others who cared! Kind regards Michael
