    I've attempted it without -r (forgot to mention that in my first mail).
      With same results. Anyhow, I need to have -r switch, otherwise things
    don't work at all.

    The reason behind the need for -r switch is that saslauthd in question
    is used only by OpenLDAP slapd daemon through use of {SASL}user at REALM as
    userPassword attribute (instructing slapd to use saslauthd to check the
    password). That is also the mechanism how the correct Kerberos realm is
    choosen for the user. For some reason, when not using -r switch, thigs
    are not working at all. In logs I can see that username and realm are
    correctly passed to saslauthd, but password verification fails unless
    saslauthd is started with -r switch. I would expect that saslauthd
    would do "the right thing" internally when kerberos5 is used for
    password verification, but it doesn't.
