自从我更新到 Debian Bullseye 后，nfs 客户端就停止工作了：
# 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
当我在同一系统上安装 5.9 内核（linux-image-5.9.0-0.bpo.5-cloud-amd64）时，它可以工作。
我也尝试过：
- Debian 测试内核（内核 5.14）- 不起作用
- Ubuntu 21.10 Impish（内核 5.13）-无法运行
- Ubuntu 20.04 Focal（内核 5.4）- 可用
假设所有系统具有相同的 NFS/Kerberos 设置，我的结论是：内核中发生了一些变化，不允许挂载 NFS/Kerberos 共享。
- 我的 KDC - Samba4 AD
- 我的 Kerberos 和 NFS 设置非常标准，就像任何指南一样
- HOSTNAME$@REALM nfs/fqdn@REALM host/... 原则在客户端和服务器键表中
我将其放入RPCGSSDOPTS="-vvv"/etc/default/nfs-common 进行调试。在以下日志中：
- nfs11-我的测试 nfs 服务器（Debian 11，内核 5.10）
- tst2-我的测试 nfs 客户端（Debian 11）
这是客户端尝试挂载 nfs 共享时的系统日志：

我搜索了很多，没有找到任何相关内容...目前，作为一种解决方法，我在所有 nfs 客户端系统中运行从以前版本反向移植的内核。但我认为这很危险，而且有东西告诉我它随时可能崩溃。
有人遇到过这样的问题吗？也许我应该调整一些东西来适应内核的变化？也许我应该修复内核错误？
更新。添加了 KDC 日志。

我看到错误。Google 找到了与旧 enctypes 相关的旧问题，没什么用。所有软件包都是最新的。Server (nfs/[email protected]) has no support for etypes
感谢大家的评论，我取得了一些进展。我安装了全新的 Samba DC，将客户端（5.10 内核）和服务器都连接到了新的 KDC - 并且成功了！新的 KDC 允许使用任何内核的 NFS 客户端挂载共享。问题似乎出在我的生产 Samba DC 上。我查看了 ldap DB，它们似乎很相似，只是在新的 dc 上添加了很少的内容，例如 3 个新对象和一些字段。目前我不知道应该在生产 DC 中调整什么以使其表现得像新的一样。重新安装将是最后的手段，因为它需要大量时间。
生产 DC 是很久以前创建的，并使用标准 samba 复制或备份进行了多次迁移。生产和新 DC 信息：
- oEMInformation：由 SAMBA 4.1.6-Ubuntu 提供
- oEMInformation：由 SAMBA 4.13.5-Debian 提供
目前 DC 在相同的 Debian 操作系统下运行。
更新2.已解决！
请参阅下面的解决方案。
答案1
Linux 在 5.10 版中取消了 Kerberos 对 RC4-HMAC-MD5 的支持。您的客户端使用该加密类型，如服务器的日志输出所示：
[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 类型可用，Samba 应该选择 aes256-cts-hmac-sha1-96。
它不在您的任何日志中，但我猜测失败的 TGS-REQ 要求 des3-cbc-sha1、aes128-cts-hmac-sha1-96、aes256-cts-hmac-sha1-96。可以通过使用参数启动 rpc.gssd 来验证这一点-vvvrr。在这种情况下，客户端的 AD 帐户没有启用所需的加密类型。如果客户端在 Samba 不支持 AES 时加入域，就会发生这种情况。您可以通过重置客户端的 AD 帐户的密码或重新加入域来启用加密类型。您还需要确保将加密类型添加到客户端的密钥表中。这可以klist -ke在客户端上运行进行验证。
如果您使用特定的服务主体，请确保将加密类型明确添加到客户端帐户（在 ADC 运行中net ads enctypes set <ACCOUNTNAME> 24）。否则，只会导出 ARCFOUR 类型。

就我而言，解决方案如下：我尝试使生产 DC 上的 LDAP DB 看起来像新 DC 上的 LDAP DB（正在运行）。所以我更改了一些字段。重新启动了所有内容。它成功了！
我到底改变了什么。
dn: DC=my,DC=domain我使用以下方法在对象中添加/更改了以下字段ldbedit -H /var/lib/samba/private/sam.ldb：
msDS-Behavior-Version: 4
msDS-NcType: 0
serverState: 1
生产 DC 在过去被重新命名，但我在以下对象中发现了剩余的名称（旧名称）：
dn: CN=<old-name>,CN=*,CN=ypServ30,CN=RpcServices,CN=System,DC=my,DC=domain
我通过用 重命名它们来解决这个问题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'
也许并非所有这些更改都是必要的，但它现在有效了。感谢您的评论！
