Hi Marc,

to clarify the current situation.
Atm there are 2 possibilities to build samba3:
   1. in the top level build dir using WAF (future default build)
       - ./configure <prefix and options> or ./configure.developer <prefix and options>
       - make
       - make install (usually as root)
     This WAF build is building both samba3 and samba4!
     But the resulting samba3 code is _not_ the same as when using the
     next option. More optimization is done and ABI version info can be used.
     Take care with such an installed libnss_winbind.so.2 (and don't use the one
     from the build dir!)
   2. from the top level build dir
      - cd source3/
      - ./autogen.sh
      - ./configure <prefix and options> or ./configure.developer <prefix and options>
      - make
      - make install (usually as root)
        The generated dynlib <top level>/nsswitch/libnss_winbind.so can be copied to
        /lib/libnss_winbind.so.2
        It does not contain any external references to other samba dynlibs.

ldd libnss_winbind.so 
        linux-gate.so.1 =>  (0xffffe000)
        libc.so.6 => /lib/libc.so.6 (0xb7694000)
        /lib/ld-linux.so.2 (0xb7834000)

compared to the one from the WAF build:
ldd /lib/libnss_winbind.so.2 
        linux-gate.so.1 =>  (0xffffe000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb7763000)
        libwinbind-client.so => /usr/local/samba/lib/private/libwinbind-client.so (0xb775f000)  !!!
        libc.so.6 => /lib/libc.so.6 (0xb75f2000)
        /lib/ld-linux.so.2 (0xb77a4000)

Hope this helps.  :-)

Cheers, Günter
