When attempting a DR operation on a domain which does not have AP installed,
then you will get the following errors:

Nov 10 15:32:52 p10k-b dr_daemon[15227]: ld.so.1: dr_daemon: fatal: libap.so: open failed: No such file or directory
Nov 10 15:32:52 p10k-b dr_daemon[15227]: dr_daemon operating in NO AP interaction mode

What the dr_daemon is attempting to do, is to communicate the fact that it is
about to change the configuration to any AP software that may be installed
on the system. (Some versions of AP, other than 2.0, can do an automatic
switch over). As AP is not installed, the libap.so file does not exist.

These error messages can safely be ignored.
