samba - Mar 2017 - Samba 4.5.7 breaks my smb-servers on Fedora 25

https://bugzilla.redhat.com/show_bug.cgi?id=1436145
anyone a clue what is going on here?

Try adding :

[share]
wide links = yes

Please test and report back in the list.

add "wide links = yes" does *not* change anything, change "wide
links =
no" to "wide links = yes" in [global] also don't change
anything - the
sharepoint is a physical folder directly below the mountpoint

I think you might be hitting a regression, see this bug report:

confirmed - that's a big price for teh fix of a unlikely symlink related 
race-condition to allow symlinks at all now :-(

Hai 

An other possible workaround, 


You can also try to add the vfs object in the share share its needed. 
In you global settings : 
   allow insecure wide links = yes
   unix extensions = no

in the share, there where needed.
 
vfs objects = (yourneeded vfs_objects) and wide links = yes

vfs object is normaly set in the share not global.
At least thats was `man smb.conf` is telling me. 
The load order of vfs_objects do matter.

For people hurt by this that urgently need a patch, here is the fix.

It applies cleanly to 4.6.x, 4.5.x, 4.4.x.

I'm looking at adding a regression test then I'll submit
to master.
