我有一个 openldap 主服务器和 2 个 openldap 从服务器。使用非自签名 CA。
openldap master:基于 stretch
slapd 2.4.44+dfsg-5+d amd64
openssl 1.1.0f-3+deb9u1 amd64命名 debian
openldap 从属:基于 stretch
slapd 2.4.44+dfsg-5+d amd64
openssl 1.1.0f-3+deb9u1 amd64命名 debian1
openldap master:名称 ldap 基于 o oracle linux 7.4
slapd 2.4.44-5.el7.x86_64
openssl-1.0.2k-8.0.1.el7.x86_64
基于 oracle linux 的 openldap 客户端无法连接到基于 debian strech 的 ldap master。
我在从属 debian 和从属 oracle linux 上所做的事情:
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**
到目前为止一切顺利 80)
现在 debian1 从属设备上可能存在问题:
root@debian1:~# openssl s_client -connect debian.contatogs.com.br:389 -CAfile /etc/ssl/contatogs.com.br/cac
ert.pem -state
CONNECTED(00000003)

但尽管出现此错误/警告,只有 debian/debian 的主/从仍然有效。
现在oracle linux根本不能工作......

我几乎可以肯定问题出在 CA,但我不知道该如何解决...80)
任何帮助都将非常感激。

嗨,为了便于以后搜索,我找到了正确的方法来消除此错误。当我为从属服务器创建证书时,我使用客户端部分(TLS Web 客户端)创建证书,正确的方法是创建服务器证书(TLS Web 服务器)。帮助我发现此错误的是 serverfault 上的另一篇帖子,其中包含以下命令:openssl verify -purpose sslserver -CAfile cacert.pem ldaprov1.crt
