Binaries that use dlopen will not list these libraries as dependencies when doing an ldd nor will they list it as "NEEDED" when using readelf unless you've added it manually to the ELF header.

Thanks a lot for answering...

I've checked my busybox options and the "use internal password and group 
functions rather than system functions" option is used...
That's also why I thought I didn't need the nsswitch.conf file at start.
Bu thanks for the dlopen() explanation
