[Samba] OS X client symlinks

[Serhii Mozghovyi]

I mean a Unix-style symlink as if created by "ln -s file link".

In my case the Finder is able to open symlinks, this is not the problem. 
The problem is that they are real normal files from the point of view of 
a client FS, not symlinks.

This is important because those files are NodeJS modules and they 
contain some relative requires: require('../blah-blah.js'). If the 
module is a symlink, those relative paths are computed from the symlink 
target by NodeJS, not the symlink itself. So symlinks are followed, as 
it's called. That happens on my server (CentOS). But when I run the same 
Node script on Mac OSX client, it doesn't work because that .js file is 
not a symlink and it's not followed and consequently the paths are 
broken because of that.


My samba server version is 4.8.3. "vfs_fruit", "vfs_catia" and 
"vfs_streams_xattr_init" are all present in Build options, as well as 
vfs_aio_fork_init, vfs_aio_pthread_init. In the Headers section, I see 
HAVE_AIO_H.
