以下是gitlab主页面上的错误：

Could not authenticate you from Ldapmain because "Undefined method `provider' for nil:nilclass".

以下是来自gitlab production.log 文件的日志：

以下是Gitlab可以从OpenLdap获得用户的证明：ApacheDirectoryStudio sreenshot

docker-compose -f docker-compose-gitlab-gateway.yml exec gitlab gitlab-rake gitlab:ldap:check

此错误与密码长度或特定域无关：admin area in Gitlab sreenshot
下面是我的gitlab.rb配置：

#LDAP

gitlab_rails['ldap_enabled'] = true

gitlab_rails['ldap_servers'] = YAML.load <<-EOS # remember to close this block with 'EOS' below
  main:
    active_directory: true 
    allow_username_or_email_login: true
    attributes:

      name: cn
      username:

我在LDAP中使用了该映像：https://hub.docker.com/r/bitnami/openldap/
我试过在gitlab.rb中将active_directory: true改为false，希望我能在里面唱歌，但这对我没有帮助。
