LDAP Certificate ldap.conf can't connect to the server

[steffus]

I would like to contact an LDAP server via Mamp Pro version 6.3 and PHP version 7.4.13. Unfortunately, I always get an error that I cannot contact the server. After a conversation with the LDAP admin, I would have to include a certificate. I have already copied the certificate root-CA.crt into the folder /etc/openldap/certs/ and specified it in the /etc/openladp/ldap.conf file.
TLS_REQCERT never
TLS_CACERT /private/etc/openldap/certs/root-CA.crt
Unfortunately without success, I have to do something else. Did I forgot something? Do I have to change another file in the MAMP?

Sorry, not familiar with this...maybe someone else who's had success can help here.
