【问题描述】：
我想做什么：
使用openssl -connect 与远程站点建立干净的连接。
网站似乎是自签名的。
What I'm getting: CONNECTED(00000003)
depth=0 CN = DC01.home.pri
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = DC01.home.pri
verify error:num=27:certificate not trusted
verify return:1
depth=0 CN = DC01.home.pri
verify error:num=21:unable to verify the first certificate
verify return:1
...
...
Verify return code: 21 (unable to verify the first certificate)
我尝试过的：
echo -n | openssl s_client -connect DC01.home.pri:636 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ldapserver.pem
echo -n | openssl s_client -connect DC01.home.pri:636 -CAfile ldapserver.pem
sudo cp ldapserver.pem /etc/ssl/certs/ldapserver.pem
sudo c_rehash /etc/ssl/certs/
echo -n | openssl s_client -connect dc01.home.pri:636 -CApath /etc/ssl/certs/
我也试过
openssl verify -CAfile /etc/ssl/certs/ldapserver.pem ldapserver.pem
openssl verify -CApath /etc/ssl/certs/ ldapserver.pem
结果
ldapserver.pem: CN = DC01.home.pri
error 20 at 0 depth lookup:unable to get local issuer certificate
我已更改 CN/主机名以保护自己。但是主机名也会添加到我的主机文件中，以防万一。

【问题讨论】：
-
站点似乎自签名，还是站点是自签名？你能发帖
ldapserver.pem吗？ -
添加了审查的 pem 文件。除非您指的是 Base64，否则我无法粘贴它，因为它是不同的主机名，以保护相关人员。我已经更改了主机名和发行者名称以配合主题。
