We are working to finally split out winbind in it's own package and not deliver it as part of samba-common This is just a heads-up that some applications may be depending on samba-common because it contained winbind, in this case you will have to change the Requirements in the spec.
The 2 packages that probably want to double check this are: system-config-samba owner: nphilipp mod_auth_ntlm_winbind owner: buc
Simo.
