Public bug reported:

Currently, Ubuntu 16.04's newest offered version of OpenLDAP is version
2.4.42. This version depends on libgssapi3 which in turn depends libkrb5
version 2.6. Many other common libraries (like gssapi_krb5) depend on
libkrb5 3.0. From what I can tell, OpenLDAP version 2.4.44 fixes this
issue, but it is not available from any of the Ubuntu repo's. It would
be fabulous if this could be fixed.
