How to overcome main: TLS init def ctx failed: -1 for slapd startup

问题

我正在尝试在我的CentOS 7节点上设置全新的OpenLDAP，该节点上曾经有一个未完成的OpenLDAP，我使用以下命令清理了它：

systemctl stop slapd
systemctl disable slapd
yum -y remove openldap-servers openldap-clients 
rm -rf /var/lib/ldap
userdel ldap
rm -rf /etc/openldap

然后，我再次使用yum安装了OpenLDAP包：

yum install openldap openldap-servers -y
yum install openldap-clients -y

rpm -qa | grep openldap
openldap-2.4.44-25.el7_9.x86_64
openldap-servers-2.4.44-25.el7_9.x86_64
openldap-devel-2.4.44-25.el7_9.x86_64
openldap-clients-2.4.44-25.el7_9.x86_64

之后，我尝试启动slapd，但启动失败，出现以下错误：

systemctl start slapd
Job for slapd.service failed because the control process exited with error code. See "systemctl status slapd.service" and "journalctl -xe" for details.

systemctl status -l slapd.service

以下是一些疑似与TLS相关的配置信息：

ls -l /etc/openldap/certs/
total 12
-rw-r--r--. 1 ldap ldap 1371 May 14 15:27 myCA.pem
-rw-r--r--. 1 ldap ldap 1379 May 14 15:31 OpenLDAP Server
-rw-r--r--. 1 ldap ldap 1675 May 14 15:30 password

file /etc/openldap/certs/myCA.pem /etc/openldap/certs/OpenLDAP\ Server /etc/openldap/certs/password
/etc/openldap/certs/myCA.pem:        PEM certificate
/etc/openldap/certs/OpenLDAP Server: PEM certificate
/etc/openldap/certs/password:        PEM RSA private key

grep -R olcTLS /etc/openldap/slapd.d
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCACertificatePath: /etc/openldap/certs
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateFile: "OpenLDAP Server"
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateKeyFile: /etc/openldap/certs/password

我怀疑之前的OpenLDAP配置可能导致TLS错误 main: TLS init def ctx failed: -1，或者 olcTLSCACertificatePath: /etc/openldap/certs 未正确选择 /etc/openldap/certs/myCA.pem。

英文:

I am trying to setup a fresh OpenLDAP on my centos7 node\

cat /etc/redhat-release
CentOS Linux release 7.8.2003 (Core)

The node had a half baked OpenLDAP, that I cleaned up using the below commands

systemctl stop slapd
systemctl disable slapd
yum -y remove openldap-servers openldap-clients 
rm -rf /var/lib/ldap
userdel ldap
rm -rf /etc/openldap

Then I have installed the OpenLDAP package again using yum

yum install openldap openldap-servers -y
yum install openldap-clients -y

rpm -qa | grep openldap
openldap-2.4.44-25.el7_9.x86_64
openldap-servers-2.4.44-25.el7_9.x86_64
openldap-devel-2.4.44-25.el7_9.x86_64
openldap-clients-2.4.44-25.el7_9.x86_64

After this; I am trying to start slapd which is failing

systemctl start slapd
Job for slapd.service failed because the control process exited with error code. See &quot;systemctl status slapd.service&quot; and &quot;journalctl -xe&quot; for details.

Here are some suspected TLS related configs

ls -l /etc/openldap/certs/
total 12
-rw-r--r--. 1 ldap ldap 1371 May 14 15:27 myCA.pem
-rw-r--r--. 1 ldap ldap 1379 May 14 15:31 OpenLDAP Server
-rw-r--r--. 1 ldap ldap 1675 May 14 15:30 password

file /etc/openldap/certs/myCA.pem /etc/openldap/certs/OpenLDAP\ Server /etc/openldap/certs/password
/etc/openldap/certs/myCA.pem:        PEM certificate
/etc/openldap/certs/OpenLDAP Server: PEM certificate
/etc/openldap/certs/password:        PEM RSA private key

grep -R olcTLS /etc/openldap/slapd.d
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCACertificatePath: /etc/openldap/certs
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateFile: &quot;OpenLDAP Server&quot;
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateKeyFile: /etc/openldap/certs/password

I suspect that either some previously half baked OpenLDAP settings are causing the TLS error main: TLS init def ctx failed: -1; or else olcTLSCACertificatePath: /etc/openldap/certs is not picking /etc/openldap/certs/myCA.pem

我决定使用vi在下面的行下面进行评论，这样做虽然有效，但我不认为这是最佳方式。

/etc/openldap/slapd.d/cn=config.ldif:olcTLSCACertificatePath: /etc/openldap/certs
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateFile: "OpenLDAP Server"
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateKeyFile: /etc/openldap/certs/password

英文:

I decided to comment below lines using vi and it works but I do not think this is the best way to do this.

/etc/openldap/slapd.d/cn=config.ldif:olcTLSCACertificatePath: /etc/openldap/certs
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateFile: &quot;OpenLDAP Server&quot;
/etc/openldap/slapd.d/cn=config.ldif:olcTLSCertificateKeyFile: /etc/openldap/certs/password
