Any idea why on C7 the DIGEST-MD5 thing going on does not set
digest-uri like it does on C6?  I guess that is really a question
for the openldap devs.

Seems more like a DNS resolution issue than an OpenLDAP issue. RHEL6 uses OpenLDAP 2.4.40, RHEL7 uses OpenLDAP 2.4.44. There haven't been any changes related to this functionality between the two. It's possible RedHat has made their own custom modifications in this arena so you might want to look for any differences there.

However, it seems more that on your CentOS 5/6 boxes that when DNS is queried for "" it gets back "" whereas on your CentOS7 box, it gets back "".

Running 'host' on the C6 and C7 machine both return the exact same four lines/IPs. Reverse DNS of the 4 IPs using the host command is also the same on both C6 and C7 machines. It really looks like OpenLDAP is
just not doing the reverse DNS on C7 when building the MD5 digest
