Gitlab connecting toLDAP

Hello I have the current configurations for Gitlab.rb:

LDAP Settings

###! Docs:
###! Be careful not to break the indentation in the ldap_servers block. It is
###! in yaml format and the spaces must be retained. Using tabs will not work.

gitlab_rails[‘ldap_enabled’] = true

###! remember to close this block with ‘EOS’ below
gitlab_rails[‘ldap_servers’] = YAML.load <<-‘EOS’
main: # ‘main’ is the GitLab ‘provider ID’ of this LDAP server
label: ‘LDAP’
host: ‘
port: ‘389’
uid: ‘uid’
method: ‘plain’ # “tls” or “ssl” or “plain”
bind_dn: ‘uid=proxyuser,o=1sync’
password: ‘’
active_directory: false
base: ‘ou=people,o=1sync’
user_filter: ‘’
group_base: ‘ou=people,o=1sync’
admin_group: ‘unixsa’

when I run gitlab-rake gitlab:ldap:check

It actually pull all the users from the LDAP and says these users able to login to Gitlab, But when I got to GitLab webui and try to login with LDAP creds it actually fails. Any Solutions?
I am using proxyuser with read access only. no password needed.
