自從我更新到 Debian Bullseye 後，nfs 用戶端停止運作：
# mount -vvt nfs4 -o sec=krb5 nfs11:/srv /mnt
mount.nfs4: timeout set for Wed Sep 15 20:25:49 2021
mount.nfs4: trying text-based options 'sec=krb5,vers=4.2,addr=x.y.11.63,clientaddr=x.y.11.42'
mount.nfs4: mount(2): Permission denied
mount.nfs4: access denied by server while mounting nfs11:/srv
當我在同一系統上安裝 5.9 核心 (linux-image-5.9.0-0.bpo.5-cloud-amd64) 時 - 它可以工作。
我也嘗試過：
- Debian 測試內核（內核 5.14）- 不起作用
- Ubuntu 21.10 Impish（核心 5.13）- 不起作用
- Ubuntu 20.04 Focal（核心 5.4）- 可以運行
假設所有系統都有相同的 NFS/Kerberos 設置，我的結論是：核心中發生了某些變化，不允許掛載 NFS/Kerberos 共享。
- 我的 KDC - Samba4 AD
- 我的 Kerberos 和 NFS 設定非常標準，就像任何操作方法一樣
- HOSTNAME$@REALM nfs/fqdn@REALM host/... 原則在客戶端和伺服器金鑰標籤中
我放入RPCGSSDOPTS="-vvv"/etc/default/nfs-common 進行調試。在以下日誌中：
- nfs11 - 我的測試 nfs 伺服器（Debian 11，核心 5.10）
- tst2 - 我的測試 nfs 用戶端 (Debian 11)
以下是客戶端嘗試掛載 nfs 共用時的系統日誌：

我用谷歌搜尋了很多，沒有找到任何相關的東西...目前，作為一種解決方法，我在所有 nfs 客戶端系統中運行以前版本的反向移植內核。但我覺得它很危險，有東西告訴我它隨時可能會壞掉。
有人遇過這樣的問題嗎？也許我應該調整一些東西來匹配核心的變化？也許我應該填補內核錯誤？
更新。新增了 KDC 日誌。

我看到錯誤。谷歌發現了一個與舊的 enctypes 相關的舊問題，沒有什麼用處。所有軟體包都是最新的。Server (nfs/[email protected]) has no support for etypes
感謝評論，我取得了一些進展。我安裝了新的 Samba DC，將客戶端（5.10 核心）和伺服器都加入新的 KDC - 並且它起作用了！新的 KDC 允許具有任何核心的 NFS 用戶端掛載共用。看來問題出在我的生產 Samba DC 。我研究了 ldap DB，看起來它們很相似，除了在新鮮的 dc 上添加了很少的內容，例如 3 個新物件和一些欄位。目前我不知道應該在生產 DC 中進行哪些調整，以使其表現得像新的 DC。重新安裝將是最後的手段，因為它需要大量時間。
生產 DC 是很久以前創建的，並使用標準 samba 複製或備份進行了多次遷移。生產和新鮮 DC 資訊：
- oE資訊：由 SAMBA 4.1.6-Ubuntu 提供
- oE資訊：由 SAMBA 4.13.5-Debian 提供
目前 DC 運作在相同的 Debian 作業系統下。
更新2.解決了！
請參閱下面的解決方案。
答案1
Linux 在 5.10 中從 Kerberos 中刪除了對 RC4-HMAC-MD5 的支持。您的用戶端使用該加密類型，如伺服器日誌輸出所示：
[2021/09/21 21:55:44.761282, 3] ../../source4/auth/kerberos/krb5_init_context.c:80(smb_krb5_debug_wrapper)
Kerberos: Client supported enctypes: arcfour-hmac-md5, aes128-cts-hmac-sha1-96, aes256-cts-hmac-sha1-96, using arcfour-hmac-md5/arcfour-hmac-md5
如果 AES 類型可用，Samba 應該選擇 aes256-cts-hmac-sha1-96。
它不在您的任何日誌中，但我猜失敗的 TGS-REQ 會要求 des3-cbc-sha1、aes128-cts-hmac-sha1-96、aes256-cts-hmac-sha1-96。這可以透過使用參數啟動 rpc.gssd 來驗證-vvvrr。在這種情況下，用戶端的 AD 帳戶未啟用所需的加密類型。如果客戶端在 Samba 不支援 AES 時加入網域，就會發生這種情況。您可以透過重設用戶端 AD 帳戶的密碼或重新加入網域來啟用加密類型。您還需要確保將加密類型新增到客戶端的金鑰表中。這可以klist -ke在客戶端上運行進行驗證。
如果您使用特定的服務主體，請確保明確將加密類型新增至客戶的帳戶（在 ADC 運作時net ads enctypes set <ACCOUNTNAME> 24）。否則僅匯出 ARCFOUR 型別。
答案2
我的案例的解決方案如下：我嘗試讓生產 DC 上的 LDAP DB 看起來像新 DC 上的 LDAP DB（正在運行）。所以我改變了一些字段。重新啟動一切。它成功了！
我到底改變了什麼。
dn: DC=my,DC=domain我使用以下命令添加/更改了對像中的以下字段ldbedit -H /var/lib/samba/private/sam.ldb：
msDS-Behavior-Version: 4
msDS-NcType: 0
serverState: 1
生產 DC 過去已重命名，但我在以下物件中發現了遺留物（舊名稱）：
dn: CN=<old-name>,CN=*,CN=ypServ30,CN=RpcServices,CN=System,DC=my,DC=domain
我透過將它們重命名來修復此問題ldbrename，例如：
ldbrename -H /var/lib/samba/private/sam.ldb 'CN=<old-name>,CN=bootparams,CN=ypServ30,CN=RpcServices,CN=System,DC=my,DC=domain' 'CN=<actual-name>,CN=bootparams,CN=ypServ30,CN=RpcServices,CN=System,DC=my,DC=domain'
也許並非所有這些改變都是必要的，但它現在有效。謝謝您的意見！
