[Pkg-samba-maint] Bug#930540: Bug#930540: samba-vfs-modules: /usr/lib/x86_64-linux-gnu/samba/vfs/nfs4acl_xattr.so No such file or directory

[L.P.H. van Belle]

Hai, 

That is correct the modules is not in the debian builds. 
if you want to use the vfs_nfs4acl_xattr module you need to recompile samba.
Or use and other repo which already have this builtin. 

Rebuilding it. 
For the build install : nfs-common 
apt get source samba 
cd samba-... 

Edit debian/rules 
Add in the line at the end --with-shared-modules=
be added : ,vfs_nfs4acl_xattr

And change the debian/changelog and debian/control files 

And rebuild it.
cd ..
apt get source samba -b 


Greetz, 

Louis
