invalid credentials - LDAP access error in git community edition

I want to setup git for version control and continous integration.

I installed git community edition using docker-compose file as described in step 2 of https://docs.gitlab.com/omnibus/docker/README.html#install-gitlab-using-docker-compose. My docker-compose.yml files looks like:

web:
  image: 'gitlab/gitlab-ce:latest'
  container_name: git
  restart: always
  hostname: 'gitserver'
  environment:
    GITLAB_OMNIBUS_CONFIG: |
      external_url 'https://gitserver.local'
      # Add any other gitlab.rb configuration here, each on its own line
  ports:
    - '80:80'
    - '443:443'
    - '22:22'
  volumes:
    - '/srv/gitlab/config:/etc/gitlab'
    - '/srv/gitlab/ssl:/etc/gitlab/ssl'
    - '/srv/gitlab/logs:/var/log/gitlab'
    - '/srv/gitlab/data:/var/opt/gitlab'

I modifed my /srv/gitlab/config/gitlab.rb to include LDAP:

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: 'x.x.x.x'
     port: 636
     uid: 'sAMAccountName'
     method: 'ssl' # "tls" or "ssl" or "plain"
     bind_dn: 'CN=git ldap,OU=Utility Accounts,OU=San Diego,OU=MYDOMAIN,DC=MYCOMPANY,DC=local'
     password: 'MyPwd'
     active_directory: true
     allow_username_or_email_login: false
     block_auto_created_users: false
     base: 'CN=git ldap,OU=Utility Accounts,OU=San Diego,OU=MYDOMAIN,DC=MYCOMPANY,DC=local'
EOS

I get the following error on login:

Could not athenticate you from LDAPmain because invalid credentials

/srv/gitlab/logs/gitlab-rails/production.log shows:

I have tried several permutations and combinations of LDAP settings but nothing seems to work. There are several similar settings/error and suggestions by users on the net on how they solved their problem but none seem to work for me.

Some of the things that I tried are 1) commenting out bind dn and pwd 2) setting uid to uid instead of sAMAccountName 3) tried both plain and ssl methods 4) setting allow_username_or_email_login to false.

This same LDAP settings is used by other apps in the company.. so nothing wrong with it.

I have been hitting the wall for the last one week. Any help is appreciated.

Thanks!

UPDATE: I tried the followign but no luck 1) Gitlab: LDAP "Invalid credentials", but credentials are right 2) Gitlab LDAP Authentication

UPDATE2: Note that am only able to login as git ldap and not as myself. I would like everyone to login with their own credentials

Note that the bind dn and base dn are exactly the same. Having CN in base dn allows only that user to login. Changing it to 'OU=MYDOMAIN,DC=MYCOMPANY,DC=local' allows all users to login
