Gitlab 和 LDAP 针对 CommuniGate Pro Server

我目前正在尝试让我们的 GitLab 向 CommuniGate Pro 服务器提供的 LDAP 进行身份验证。使用命令行测试（如ldapsearch）时，我成功进行了身份验证并获取了信息。但是当我尝试从 GitLab 的 Web 界面执行此操作时，我得到了

由于“凭据无效”，无法从 Ldapmain 对您进行身份验证。

从 LDAP 服务器上的日志中我看到以下内容：

当我尝试时ldapsearch：

ldapsearch -x -LLL -H ldaps://mx01.ldap.net -D '[email protected]' -W -b 'cn=domain.bg' "(uid=f.lastname)"

我可以验证：

我的配置如下：

main:
  label: 'Domain.Bg LDAP'
  host: 'mx01.ldap.net'
  port: 636
  uid: 'uid'
  method: 'ssl'
  bind_dn: '[email protected]'
  password: 'password'
  active_directory: false
  allow_username_or_email_login: true
  base: 'top'
  user_filter: ''

检查RAILS_ENV=production gitlab-rake -v --trace gitlab:ldap:check也成功了。

有没有人遇到过类似的问题？从日志中我看到的内容来看，我认为问题出BINDing as 'uid=f.lastname,cn=domain.bg'在通过 postmaster 进行身份验证之后。有没有办法让用户在通过 postmaster 身份验证后使用 GitLab？BINDing as '[email protected]'

答案1

为了uid=f.lastname,cn=domain.bg与 CommuniGate 绑定，该记录应包含该userPassword属性。可以配置 CommuniGate 中的 LDAP 中央目录以将帐户密码复制到目录记录中。

另一个选项是在 CommuniGate 中启用 LDAP 直接配置选项：在这种情况下，使用指向帐户记录的 DN 的操作将在服务器帐户上下文中运行，而不是在 LDAP 目录记录上下文中运行。
