[PATCH] Fix MSDFS with POSIX paths in vfs_dfs_samba4

[Robin McCorkell]

Could I get a review of this patch? I don't know if this is the right
way to go about it (there's a lp_posix_pathnames() that controls this
functionality in the source3 code, but it's not available in source4).
Any tips?

Thanks,
Robin McCorkell
