Thank you, this clarifies it for me.
However, isn't this a confusing use of a standard autoconf feature?
Running ./configure --help says the following about sysconfdir:
--sysconfdir=DIR read-only single-machine data in DIR [PREFIX/etc]
That is a bit confusing and led me to believe that --sysconfdir could be
used to change MIT krb5's expected located of the system krb5.conf file.
But now I know (and maybe it should be documented) that MIT krb5 will
read both, /etc/krb5.conf, and @SYSCONFDIR@/krb5.conf; not only does it
read both, it merges them, and duplicated entries are treated as if they
appear twice too, and that makes a difference with profile_get_values()
and multi-value parameters.
Cheers,
Nico
