Question

我正在使用Grafana 4.2.0。我正在尝试在应用程序中集成LDAP功能。我在LDAP中创建了一个用户ldapuser1，但是当我尝试使用此用户名登录Grafana时，我收到错误为＆＃34;错误=＆＃34; Ldap搜索匹配多个条目，请查看您的过滤器设置＆＃ 34;＆＃34;

来自grafana.log的错误消息如下：

t=2017-05-26T05:59:28-0700 lvl=eror msg="Error while trying to authenticate user" logger=context userId=0 orgId=0 uname= error="Ldap search matched more than one entry, please review your filter setting"

请在下面找到ldap.toml文件供您参考

# In POSIX LDAP schemas, without memberOf attribute a secondary query must be made for groups.
# This is done by enabling group_search_filter below. You must also set member_of= "cn"
# in [servers.attributes] below.

# Users with nested/recursive group membership and an LDAP server that supports LDAP_MATCHING_RULE_IN_CHAIN
# can set group_search_filter, group_search_filter_user_attribute, group_search_base_dns and member_of
# below in such a way that the user's recursive group membership is considered.
#
# Nested Groups + Active Directory (AD) Example:
#
#   AD groups store the Distinguished Names (DNs) of members, so your filter must
#   recursively search your groups for the authenticating user's DN. For example:
#
#     group_search_filter = "(member:1.2.840.113556.1.4.1941:=%s)"
#     group_search_filter_user_attribute = "distinguishedName"
#     group_search_base_dns = ["ou=groups,dc=grafana,dc=org"]
#
#     [servers.attributes]
#     member_of = "distinguishedName"

## Group search filter, to retrieve the groups of which the user is a member (only set if memberOf attribute is not available)
# group_search_filter = "(&(objectClass=posixGroup)(memberUid=%s))"
## Group search filter user attribute defines what user attribute gets substituted for %s in group_search_filter.
## Defaults to the value of username in [server.attributes]
## Valid options are any of your values in [servers.attributes]
## If you are using nested groups you probably want to set this and member_of in
## [servers.attributes] to "distinguishedName"
# group_search_filter_user_attribute = "distinguishedName"
## An array of the base DNs to search through for groups. Typically uses ou=groups
# group_search_base_dns = ["ou=groups,dc=grafana,dc=org"]

# Specify names of the ldap attributes your ldap uses
[servers.attributes]
name = "ldapuser1"
surname = "ldapuser1"
username = "ldapuser1"
#member_of = "People"
email =  "ldapuser1@cloudera.com"

# Map ldap groups to grafana org roles
[[servers.group_mappings]]
group_dn = "cn=admins,dc=grafana,dc=org"
org_role = "Admin"
# The Grafana organization database id, optional, if left out the default org (id 1) will be used
# org_id = 1

[[servers.group_mappings]]
group_dn = "cn=users,dc=grafana,dc=org"
org_role = "Editor"

[[servers.group_mappings]]
# If you want to match all (or no ldap groups) then you can use wildcard
group_dn = "*"
org_role = "Viewer"

我正在使用本地OpenLDAP服务器。我无法找出问题的根本原因。我是LDAP新手并且是第一次配置它。

Answer 1

您分别有两个ldapuser1和ldapuser2条目（每个用户一个用户和一个组）。当您在cn = ldapuser1上搜索时，openldap无法区分这两个条目，即使它们具有不同的dns。您需要搜索所有条目中唯一的内容。

我看到两个选项：

1）搜索唯一属性，例如uid。这将找到uid = ldapuser1，ou = People，dc = cloudera，dc = com但不是cn = ldapuser1，ou = Groups，dc = cloudera，dc = com，因为该组没有uid。

2）将搜索过滤器更改为仅包括用户，例如。（及（objectClass的=为inetOrgPerson）（CN =％S））

Answer 2

第一个问题似乎是您的Grafana LDAP配置。让我们自上而下地浏览您的TOML文件。

绑定请求用于启动LDAP服务器的身份验证。对于简单绑定，我们需要用户的可分辨名称（dn）和密码。由于您希望允许用户显示用户标识符（uid）而不是可分辨名称，因此Grafana必须通过搜索目录将uid映射到dn。 bind-dn是指Grafana将用于检索身份验证用户的可分辨名称（dn）的用户帐户。这绝对不是命名上下文dc=cloudera,dc=com，而是现有的用户条目。

部分servers.attributes允许您将Grafana内部名称映射到实际的LDAP属性类型名称。即使您没有将givenName添加到您的用户条目，我建议您遵循映射，但是：

name = givenName
surname = sn
username = uid
email = mail

组映射用于用户授权。每个group_dn必须引用目录中的现有用户组。一个小组的成员被分配了某个预定义的Grafana角色。您的样本组有点无用，因为它们会遗漏任何成员属性。

另外，请务必将您的group_dn（...，dc = grafana，dc = org）调整为您的LDAP上下文（dc = cloudera，dc = com）。

错误=＆＃34; Ldap搜索匹配多个条目，请查看您的过滤器设置＆＃34;与Grafana LDAP
