This will not work. There is a protocol used between libwbclient and winbind. 
These packages NEED to be the same version. If you link pam_winbind and 
nss_winbind statically and winbind gets updated it is likely that your module 
it not able to talk to winbind anymore!

The PAM and NSS module and libwbclient need to be updated together with 

When upgrading PAM and NSS module, the machine probably needs a reboot so that 
changes are applied.

To make it clear this is not a Samba issue! It is how PAM and NSS works ...
