我最近接管了几台服务器的管理。两台服务器都需要允许jenkins用户通过 ssh 连接，这些用户由 LDAP 管理。当我输入 时，两台服务器都会显示用户信息id jenkins。
我在两台服务器中为用户创建了一个home目录。两台服务器在用户文件中都包含相同的公钥authorized_keys。所有权限设置都相同。
当尝试server A以用户身份通过 ssh 进入时jenkins，日志会显示以下内容。
debug1: Authentications that can continue: publickey
debug3: start over, passed a different list publickey
debug3: preferred gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive,password

Server B当以同一台服务器的用户身份ssh 进入时jenkins，日志显示的内容如下。
debug1: Authentications that can continue: publickey
debug3: start over, passed a different list publickey
debug3: preferred gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive,password

基本上，jenkins用户可以通过 ssh 进入Server A，但当Server B两台服务器都包含相同的用户主目录时则不行。我不得不修改/etc/passwd和/etc/shadow文件Server A才能使其正常工作。
这里发生了什么？
答案1
我getent passwd jenkins按照 David 的建议运行，结果显示两台机器上用户的主目录路径设置不同。这解决了我的问题。
