Comment 6 for bug 1764744

actually, that SASL issue is likely due to 389-ds-base hardcoding the saslpath for x86 and arm.. Here's a version of it for bionic which adds support for s390x (and ppc64el), if you're able to test:

yes, it's a silly ppa but one that has builders for all archs :)

grepping for sasl2 gives the right path in libslapd.so.0.1.0 at least..
