SSL例程：ssl23_write：ssl握手失敗：s23_lib.c：177：

我有一個 openldap 主伺服器和 2 個 openldap 從伺服器。使用非自簽名 CA。

openldap master：基於stretch
slapd 2.4.44+dfsg-5+d amd64
openssl 1.1.0f-3+deb9u1 amd64命名debian

openldap Slave：基於stretch
slapd 2.4.44+dfsg-5+d amd64
openssl 1.1.0f-3+deb9u1 amd64命名debian1

openldap master：基於名稱 ldap o oracle linux 7.4
slapd 2.4.44-5.el7.x86_64
openssl-1.0.2k-8.0.1.el7.x86_64

基於oracle linux的openldap客戶端無法連線到基於debian strech的ldap master。

我在slave debian 和slave oracle linux 上做過的事情：

root@debian1:~# openssl verify -CAfile /etc/ssl/contatogs.com.br/cacert.pem /etc/ssl/contatogs.com.br/newcerts/cn\=debian1\,ou\=computers\,dc\=contatogs\,dc\=com\,dc\=br.crt.pem 
/etc/ssl/contatogs.com.br/newcerts/cn=debian1,ou=computers,dc=contatogs,dc=com,dc=br.crt.pem: **OK**

[root@ldap ~]# openssl verify -CAfile /etc/openldap/cacerts/cacert.pem /etc/openldap/certs/cn\=ldap\,ou\=>
/etc/openldap/certs/cn=ldap,ou=computers,dc=contatogs,dc=com,dc=br.crt.pem: **OK**

到目前為止還不錯 80)

現在 debian1 從站可能出現問題：

root@debian1:~# openssl s_client -connect debian.contatogs.com.br:389 -CAfile /etc/ssl/contatogs.com.br/cac
ert.pem  -state 
CONNECTED(00000003)

但儘管有此錯誤/警告，僅使用 debian/debian 的主/從仍可工作。

現在oracle linux根本就不能用了…

[root@ldap ~]# 
<contatogs.com.br:389 -CAfile /etc/openldap/cacerts/cacert.pem  -state

我幾乎可以肯定問題是 CA，但我不知道如何修復...80)

任何幫助將不勝感激。

您好，對於未來的搜索，我已經找到了消除此錯誤的正確方法。當我為從站建立憑證時，我使用客戶端部分（TLS Web 用戶端）創建，正確的做法是建立一個憑證作為伺服器（TLS Web 伺服器）。幫助我發現此錯誤的是 serverfault 上的另一篇文章，其中包含此命令： openssl verify - Purpose sslserver -CAfile cacert.pem ldaprov1.crt
