nisのインストール後にPAMが破損するのはなぜですか？

私はシステム管理の経験を持つソフトウェアエンジニアで、現在以前はWindowsインフラストラクチャしかなかった新しいワークショップでいくつかのLinuxインフラストラクチャを設定しようとしています。政治的な理由から、現在のActive Directory設定と単純に統合することはできず、最初から始める必要がありました。私はDebianを使用しています。

私は現在kerbos、ldap、nfs、nisを設定しようとしています。サーバーが正しく設定されており、Kerberosを使用してログインをテストし、nisクライアントがサーバーと通信し続け、NFSドライブもマウントできるので、すべてがうまく機能すると思います。

クライアントにnisをインストールした後にリカバリモードで起動しないと、rootアカウントでログインすらできません。

一日半の間この問題を解決しようとしましたが、アイデアはありません。

pamが次に出力するので、これが問題だと思います。/var/log/auth.log

なぜそうなのかよく分からない。これはすべてクライアントがnisパッケージをインストールした後に開始されましたが、出力であると判断した場合、nisがサーバーと通信しているため問題ではないようです。systemctl status nis

systemd[1]: Starting LSB: Start NIS client and server daemons....
nis[1348]: Setting NIS domainname to: domain.
nis[1348]: Starting NIS services: ypbind.
systemd[1]: Started LSB: Start NIS client and server daemons..

nisも削除しましたが（起動時にnisがインストールされたため）、再起動後も問題が解決されました。

nisの依存関係を確認しましたが、なぜこれが起こるのか理解できません。私はPamが私の/etc/nsswitch.confファイルを分析していると思います。必要に応じて下から見ることができます。

passwd:         compat files systemd nis
group:          compat files systemd nis
shadow:         files
gshadow:        files

修正する @Michael Ströderが提案したようにsssdに切り替えましたが、何も変わりませんでした。
