Below the TODO section on http://ca.samba.org/samba/devel/ the link provided for the MS CIFS License is http://msdn.microsoft.com/library/en- us/dnkerb/html/Finalcifs_LicenseAgrmnt_032802.asp It should be http://msdn.microsoft.com/library/default.asp?url=/library/en- us/dnkerb/html/cifs_license_agreement.asp
This link was updated on 3 May 2004. I assume the problem was with mirroring -- ca.samba.org hosting an outdated version of the page. The mirror is currently listing the correct page. Sorry for the inconvience.
