gitlab配置LDAP认证和SMTP

配置LDAP认证 (实验环境LDAP认证服务器类型为Microsoft AD)

编辑 /etc/gitlab/gitlab.rb配置文件：

### LDAP Settings
###! Docs: https://docs.gitlab.com/omnibus/settings/ldap.html
###! **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: 'LDAP server IP'
     port: 389
     uid: 'sAMAccountName'
     bind_dn: 'bindDN'  #有查询权限的用户DN
     password: 'password'
     encryption: 'plain' # "start_tls" or "simple_tls" or "plain"
     verify_certificates: true
     smartcard_auth: false
     active_directory: true
     allow_username_or_email_login: true
     lowercase_usernames: false
     block_auto_created_users: false
     base: 'baseDN'
     user_filter: ''
#     ## EE only
#     group_base: ''
#     admin_group: ''
#     sync_ssh_keys: false
#
#   secondary: # 'secondary' is the GitLab 'provider ID' of second LDAP server
#     label: 'LDAP'
#     host: '_your_ldap_server'
#     port: 389
#     uid: 'sAMAccountName'
#     bind_dn: '_the_full_dn_of_the_user_you_will_bind_with'
#     password: '_the_password_of_the_bind_user'
#     encryption: 'plain' # "start_tls" or "simple_tls" or "plain"
#     verify_certificates: true
#     smartcard_auth: false
#     active_directory: true
#     allow_username_or_email_login: false
#     lowercase_usernames: false
#     block_auto_created_users: false
#     base: ''
#     user_filter: ''
#     ## EE only
#     group_base: ''
#     admin_group: ''
#     sync_ssh_keys: false
EOS

修改完配置文件后，

gitlab-ctl reconfigure #重载配置文件

gitlab-rake gitlab:ldap:check #检查是否能够正常获取用户信息

gitlab-ctl restart重启后重新登录gitlab，登录页面会有LDAP方式：

SMTP配置 (实验环境中SMTP server类型为Microsoft Exchange)

编辑 /etc/gitlab/gitlab.rb配置文件：

### GitLab email server settings
###! Docs: https://docs.gitlab.com/omnibus/settings/smtp.html
###! **Use smtp instead of sendmail/postfix.**

gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "mail server"
gitlab_rails['smtp_port'] = 587
gitlab_rails['smtp_user_name'] = "smtp user" # SMTP认证用户名
gitlab_rails['smtp_password'] = "smtp user password"
gitlab_rails['smtp_domain'] = "domain"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_openssl_verify_mode'] = 'none' #报openssl错误时，启用此选项
# gitlab_rails['smtp_tls'] = false

修改配置完成后

gitlab-ctl reconfigure #重载配置文件

gitlab-rails console进入控制台，发送测试邮件： Notify.test_email('receiver mail', 'title', 'content').deliver_now

如果出现如下SMTP权限错误，SMTPFatalError (550 5.7.60 SMTP; Client does not have permissions to send as this sender)

可能是SMTP server上的防垃圾邮件限制，此时需要在配置文件加上sender mail地址，确保smtp验证用户名和sender是一致的。

 gitlab_rails['gitlab_email_enabled'] = true
 gitlab_rails['gitlab_email_from'] = 'sender address'  #sender address和上段smtp认证用户名配置一致
 gitlab_rails['gitlab_email_display_name'] = 'xxx'
 gitlab_rails['gitlab_email_reply_to'] = ''
