Gitlab project access to specific AD users


We have installed gitlab-ce-7.10.4~omnibus-1.x86_64 and able to integrate with AD authintication. Now, users are able to login with their AD credentials. As a admin we created few repos successfully. Here the problem araised. While giving access to certain AD users, at “people” field in “Users with access to this project” not showing any AD users to be allowed members in the created projects.

Can you please help out here how to allow certain AD users for specific gitlab projects. Here is my ldap configuation in gitlab.
gitlab_rails[‘ldap_enabled’] = true
gitlab_rails[‘ldap_servers’] = YAML.load <<-‘EOS’ # remember to close this block with ‘EOS’ below
main: # ‘main’ is the GitLab ‘provider ID’ of this LDAP server
label: ‘AD Login’
host: ‘’
port: 389
uid: ‘sAMAccountName’

bind_dn: ‘CN=gitadmin,CN=Users,DC=example,DC=com’

active_directory: true
allow_username_or_email_login: false
block_auto_created_users: false
