I was hoping that someone else would respond to this. ;-)

Oh, did you "make install" right over your Owl system? If so, you made
your system files inconsistent with the RPM database (bad for integrity
checking and for further updates of the system). Also, we do not use
some of the programs that are a part of the shadow suite. We use other
implementations, coming from other packages. In particular, the
passwd(1) command on Owl comes from SimplePAMApps, not from the shadow
suite. You've essentially overwritten it with the shadow suite
implementation. :-(

All of the above login.defs settings are Owl extensions. The above
error messages mean that you also did not apply our patches to the
shadow suite. :-( If so, you've dropped the tcb support from useradd(8)
and from all other user management commands. You've also dropped our
security fixes and security "hardening" enhancements, and more. In
Owl-current, we have a total of 20 patch files to the shadow suite:

If my guesses are correct, then what you have now is not quite Owl. It
is Owl minus our shadow suite and with some of the other programs
overwritten with the shadow suite implementations. To clean up this
mess, you may "make uninstall" your shadow suite, then "make
installworld" Owl over your system. If the "make uninstall" doesn't
work or doesn't remove all of the files that were installed, you may
nevertheless proceed with the "make installworld" and then use some
"rpm -qal | sort", "find ... | sort", and "comm ..." commands to
identify the extra non-Owl shadow suite files that you would have left
lying on the system. You would need to remove those files.
