How should I check whether they are linked?
My Postgres version is 10.6 and I have this output for "yum list | grep ldap | sort":

And which version is that? (And which version of Postgres?)
Digging around in our git history, I came across this:
Author: Noah Misch <noah@leadboat.com>
Branch: master Release: REL9_5_BR [d7cdf6ee3] 2014-07-22 11:01:03 -0400
Diagnose incompatible OpenLDAP versions during build and test.
With OpenLDAP versions 2.4.24 through 2.4.31, inclusive, PostgreSQL
backends can crash at exit. Raise a warning during "configure" based on
the compile-time OpenLDAP version number, and test the crash scenario in
the dblink test suite. Back-patch to 9.0 (all supported versions).
which sounds a fair bit like what you are describing.
