[Samba] symlinks are invalid folders for windows 10 clients

[Sébastien QUESSON]

Hi

to make folders followable for windows 10 clients, we have to enable both wide links and allow insecure wide links
cifs clients on ubuntu doesn't need this parameters...
samba server: debian 9 / samba 4.5.8 as domain member
testparm -s -v | egrep 'extensions|links'
        allow insecure wide links = Yes
        unix extensions = Yes
        follow symlinks = Yes
        wide links = Yes

On a old samba server, both windows and ubuntu can follow symlinks with secure configuration.
samba server : debian 6 / samba 3.6.6 as domain member
        unix extensions = Yes
        allow insecure wide links = No
        wide links = No
        follow symlinks = Yes


My symlinks are relative or absolute, but everytime inside the share.
What's the problem?

Best regards,
