AD用户建立AD-FreeIPA信任后无法登录IPA客户端

我在FreeIPA和AD之间建立了信任关系，并向FreeIPA服务器添加了一些AD用户，所有这些用户都可以成功登录IPA服务器端。但可以登录IPA客户端。这是我用来向 FreeIPA 添加工作站的命令

ipa-client-install -U -f --enable-dns-updates --domain example.com --ntp-server=phoenix.example.com --server=phoenix.example.com -p EXAMPLE.COM -p admin -w '$EXAMPLE' --hostname=$HOSTNAME --automount-location=default --no-dns-sshfp --preserve-sssd

检查后/var/log/message我 /var/log/secure收到了这个警告

/var/log/secure:

但是当我输入 id 时，[email protected]它会显示这个用户信息。

答案1

问题解决了，看来我需要手动打开相应的端口。编辑/etc/sysconfig/iptables，添加以下代码

*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
# -A INPUT -s ad_ip_address -p tcp -m multiport --dports 389,636 -m state --state NEW,ESTABLISHED -j REJECT
-A INPUT -p tcp -m multiport --dports 80,88,443,389,636,88,464,53,138,139,445 -m state --state NEW,ESTABLISHED -j ACCEPT
-A INPUT -p udp -m multiport --dports 88,464,53,123,138,139,389,445 -m state --state NEW,ESTABLISHED -j ACCEPT

-A INPUT -p tcp -j REJECT
