Apache2 Kerberos 身份验证未按预期工作

我使用的是 Apache 2.4.23，想在访问我的 Intranet 时使用 kerberos 身份验证。我的 apache 配置如下（不要对第一个 vhost firma2020 感到恼火，这是一个临时 vhost，因为我们有一个反向代理可以从外部访问特定站点，所以我不得不添加这个虚拟主机）

但当我输入我的凭证时，即使我不在正确的组中，我也可以访问

我不明白为什么我只需输入正确的用户名和密码就可以访问。我本以为会被阻止，因为未分配 ldap 组

答案1

我发现了我的错误。

首先它不是

require valid-user svc_intranet2019_sso你必须使用require user svc_intranet2019_sso

我还必须设置一个<Requireany> </Requireany>现在看起来像这样

        AllowOverride All
        Options +FollowSymLinks

                ###############SSO + LDAP CONFIG################
                AuthType Kerberos
                AuthName "Intranet Login"
                KrbAuthRealm firma.de
                KrbServiceName HTTP/[email protected]
                Krb5Keytab /etc/apache2/apache.keytab
                KrbMethodK5Passwd on
                KrbMethodNegotiate off 

                AuthLDAPURL "ldap://server.firma.de:3268/DC=int,DC=firma,DC=de?userPrincipalName"
                AuthLDAPBindDN '[email protected]'
                AuthLDAPBindPassword '1Bqj*9y_oDv!43z'
<RequireAny>
Require ldap-group CN=AP_UG_Intranet_Zugriff,OU=GrpAppl,OU=ZentraleRessourcen,OU=firma,DC=int,DC=firma,DC=de

                ## User für Icinga Checks - IMA-0001863544 ##
                Require user svc_intranet2019_sso
</RequireAny>
</Directory>

现在它就可以工作了:)
