Docs/howto/CentOS Implementing LDAP with SSL
When trying to switch from LDAP to LDAPS, you got several errors. This issue only happens if you work with LDAPS with certificates. Your /etc/ldap.conf all correct, all certificates installed and the ldapsearch working.
The php on Zabbix can't find the rights variables with the location of the certificates. When you switch the and it failing altogether. With your /etc/ldap.conf all correct, you still cant make it work inside Zabbix.
To solve this issue, edit the frontend to add the lines below: conf/zabbix.conf.php
putenv("LDAPTLS_CACERT=/etc/ldap/my_custom_cacert.pem"); putenv("LDAPTLS_CERT=/etc/ldap/my_custom_clientcrt.pem"); putenv("LDAPTLS_KEY=/etc/ldap/my_custom_clientkey.pem");
After restart your web server do the configuration again: go to Administration -> Authentication Test it. It should work now :)
