I think I didn't look carefully enough at the error message. Actually 
the package libpam-winbind comes with the file pam_winbind.so in the 
folder "/lib/x86_64-linux-gnu/security/" while it was missing in the 
folder "/lib/security/". You could try these commands to link the 
existing file to the expected location:

sudo mkdir -p /lib/security/
sudo ln -s ../x86_64-linux-gnu/security/pam_winbind.so /lib/security/
