Apache2 Kerberos 驗證未如預期運作

我使用 Apache 2.4.23 並希望在訪問我的 Intranet 時使用 kerberos 身份驗證。我的 apache 配置看起來像（不要被第一個虛擬主機 Firma2020 激怒，那是一個臨時虛擬主機，因為我們有一個反向代理可以從外部訪問特定站點，所以我必須添加這個虛擬主機）

但是當我輸入我的憑證時，即使我不在正確的群組中，我也可以訪問

我不明白為什麼我只需輸入正確的使用者名稱和密碼即可獲得存取權限。我預計會被阻止，因為 LDAP 群組未分配

答案1

我發現了我的錯誤。

首先它不是

require valid-user svc_intranet2019_sso你必須使用require user svc_intranet2019_sso

我還必須設置一個<Requireany> </Requireany>它現在看起來像這樣

        AllowOverride All
        Options +FollowSymLinks

                ###############SSO + LDAP CONFIG################
                AuthType Kerberos

                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>

有了這個，它現在可以工作了:)
