Samba4 (which is under review for inclusion into Fedora) will soon ship
some data (the Active Directory schema) under less-than-usual licence
The attached file gives the text.
I believe it is no less free than Free licences on Fonts that require
redistribution with software.
The review ticket is: https://bugzilla.redhat.com/show_bug.cgi?id=453083
If this causes a problem, presumably the packager can strip
setup/ad-schema (and the whole server implementation) from the tarball.
