Hello,Ulf
Thank you for your reply
I made a mistake in the original text, and I have now corrected it
Configure the ldap.conf certificate on the client as follows:
TLS_CACERT /usr/local/openldap-2.6.6/cert/demoCA/newcerts/cacert.pem
In addition, my server name: root@slapd:/usr/local/openldap/etc/openldap# hostname -f slapd.zxactions.com
Later I re-execute the operation, the error is still the same as the above information, do not know is I generated a self-signed certificate problem or other software problems?
