int acldb_vfs_ftruncate(struct files_struct *fsp, int fd, SMB_OFF_T offset)
{
   int result;

   DEBUG(ACLINFO,("acldb_vfs_ftruncate: fd=%d\n", fd));

   /* Root wrapper */
   become_root();
   result = vfswrap_ftruncate(fsp, fd, offset);
   unbecome_root();

   DEBUG(ACLINFO,("acldb_vfs_ftruncate: %s\n", STATUS(result!=-1)));
   return result;
}

Root wrapper avoids connected user's unix security context. I don't
think this function could be problem, unless become_root() has some
strange side effects. I'll check...
