This is not only for the apache2 process, also sssd_be, sm-mta & php spawn the
same warnings.
A downgrade to 2.4.40+dfsg-1+deb8u3 did solve the issue.
Thank you for the report. Indeed one thing that changed in this version
is that libldap now initializes libsasl eagerly, instead on on first
use, so previously these messages might have only appeared when a
process invoked SASL via LDAP - or not at all.
You are the first to mention an issue like this, though, so I wonder if
it's caused by a local configuration on your side.
Is your libsasl2-modules-ldap up-to-date with libsasl2-2? What do you
use it for?
