Abort
ursaminor:/usr/local/sbin# ll ktrace.out

93873 ktrace CALL execve(0xbfbfed7f,0xbfbfec44,0xbfbfec4c)
93873 ktrace NAMI "./smbd"
I have no idea how to interpret this dump.
OTOH ldd says everything looks fine:
ursaminor:/usr/local/sbin# ldd ./smbd
./smbd:
libcrypt.so.5 => /lib/libcrypt.so.5 (0x281a1000)

Any suggestion where to dig further?
Read about the latest ERRATA NOTICES's. There is something with
PIE-library's (which are used by Samba) which defaults to doesn't-work in
8 and still works in 7. People are working on a real fix for 8.
In the ERRATA NOTICES is a setting which you can set to does-work.
