LDAPS - cause = ldap_bind(): Unable to bind to server: Can't contact LDAP server

Hello,

I can't get LDAPS to work with ProjeQtor.

Authentication works fine in simple ldap.

My configuration :
base DN LDAP : CN=Users,DC=mydomain,DC=local
ldaps://HOSTNAME.mydomain.local/
Port LDAP : 636
Version LDAP : 3
Filter for users : sAMAccountName=%USERNAME%

My tests :

- Authentification LDAP simple with this configuration : OK
base DN LDAP : CN=Users,DC=mydomain,DC=local
ldap://HOSTNAME.mydomain.local/
Port LDAP : 389
Version LDAP : 3
Filter for users : sAMAccountName=%USERNAME%

- Check rules firewall port : OK

- Test telnet with port 636 to ldap server : OK

- Test the DNS name resolution of the LDAP server from the Projeqtor server: OK

- Checking SSL activation with PHP: OK
php -i | grep -i openssl

I can't find a solution to my problem ...

Thank you in advance for your assistance.
