Gitlab with AD SSL without authentication

Hello, does anyone know if it’s possible to setup gitlab so that it queries a Microsoft AD server for login over ssl and does not use a bind account?

My config is as per below.

ldap:
enabled: true
sync_time:
host: ‘$serverip’
port: 636
uid: ‘sAMAccountName’
method: ‘ssl’
bind_dn: ‘’
password: ‘’
active_directory: true
allow_username_or_email_login: false
base: ‘$base’
user_filter: ‘’
timeout: 60
block_auto_created_users: true

I adjusted /etc/openldap/ldap.conf and added TLS_REQCERT never

My output from trace seems to be fine. But it doesn’t seem to work. Any tips or advice appreciated.

[root@gitlab etc]# gitlab-rake gitlab:ldap:check --trace
