It seems correct, the behaviour is depending on how the NSS backend
library was linked. Build libnss_winbind.1 without the linker option
"-B symbolic" and, bingo, there is only one client connection per smbd.

For the PAM module libpam_winbind.1 preferred local resolution of
symbols with "-B symbolic" is still required to work properly. So
optimally the two backend libraries should be linked differently.
