介绍

本教程适用于9-11+版本的Grafana，域控（AD）使用Windows Server 2022搭建，域控等级为 2016。

域控域名为 songxwn.com

最终实现AD用户统一认证，统一改密，Grafana用户自动添加。权限由Grafana控制

全局开启LDAP

修改/etc/grafana/grafana.ini 文件

vim etc/grafana/grafana.ini

修改并取消注释以下参数即可

[auth.ldap]
enabled = true
config_file = etc/grafana/ldap.toml
allow_sign_up = true

配置LDAP对接文件

修改/etc/grafana/ldap.toml文件

vim etc/grafana/ldap.toml

文件示例

• • host 为域控制器地址。
• • port 默认为 389即可，不开启加密
• • bind_dn 为域控账号，用于搜索域控账号
• • bind_password 为上面账号的密码
• • search_filter AD固定为(sAMAccountName=%s)
• • search_base_dns 为域控路径，可以去ADSI查看

用户组权限映射 - [[servers.group_mappings]]

• • group_dn 为用户组的路径
• • org_role 为在Grafana用户组的权限，有 Admin、Editor、Viewer （管理、编辑、只读）

如下面所示，我将it1 映射为了Editor，it2 组为Viewer

PS：具体路径建议用ADSI工具查看。

## For Posix or LDAP setups that does not support member_of attribute you can define the below settings
## Please check grafana LDAP docs for examples
# group_search_filter = "(&(objectClass=posixGroup)(memberUid=%s))"
# group_search_base_dns = ["ou=groups,dc=grafana,dc=org"]
# group_search_filter_user_attribute = "uid"

# Specify names of the ldap attributes your ldap uses
[servers.attributes]

email =  "mail"

# Map ldap groups to grafana org roles


[[servers.group_mappings]]
group_dn = "cn=it1,cn=users,dc=songxwn,dc=com"
org_role = "Editor"

[[servers.group_mappings]]
# If you want to match all (or no ldap groups) then you can use wildcard
group_dn = "cn=it2,cn=users,dc=songxwn,dc=com"
org_role = "Viewer"

重启和测试

systemctl restart grafana-server.service 

# 重启之后，上述配置才能生效。
