Thanks!

 readelf -d nss_wins.so.1

Dynamic section at offset 0x1d20 contains 32 entries:
  Tag                Type                  Name/Value
 0x0000000000000001 NEEDED               Shared library: [libwbclient.so.0]
 0x0000000000000001 NEEDED               Shared library:
[libwinbind-client-samba4.so]
 0x0000000000000001 NEEDED               Shared library:
[libreplace-samba4.so]
 0x0000000000000001 NEEDED               Shared library: [libcrypt.so.5]
 0x0000000000000001 NEEDED               Shared library: [libc.so.7]
 0x000000000000000e SONAME               Library soname: [nss_wins.so.1]
 0x000000000000000f RPATH                Library rpath: [/usr/local/lib]
 0x000000000000001d RUNPATH              Library runpath: [/usr/local/lib]

Looking at other libs, they have the settings

 0x000000000000000f RPATH                Library rpath:
[/usr/local/lib/samba4/private:/usr/local/lib]
 0x000000000000001d RUNPATH              Library runpath:
[/usr/local/lib/samba4/private:/usr/local/lib]

What is the best way to fix this ? It seems I can do a quick libmap
entry and it seems to correct it


[/usr/local/lib/nss_wins.so.1]
libwinbind-client-samba4.so     
/usr/local/lib/samba4/private/libwinbind-client-samba4.so
libreplace-samba4.so /usr/local/lib/samba4/private/libreplace-samba4.so

 ldd nss_wins.so.1
nss_wins.so.1:
        libwbclient.so.0 => /usr/local/lib/samba4/libwbclient.so.0
(0x801003000)
        libwinbind-client-samba4.so =>
/usr/local/lib/samba4/private/libwinbind-client-samba4.so (0x801213000)
        libreplace-samba4.so =>
/usr/local/lib/samba4/private/libreplace-samba4.so (0x801417000)
        libcrypt.so.5 => /lib/libcrypt.so.5 (0x80066b000)
        libc.so.7 => /lib/libc.so.7 (0x80024a000)

This is something that needs to be fixed in the port at build time ?

Thanks again,
