FortiCloud EMS Authentication server LDAPS
Hello,
We are trying to switch our EMS authentication server from LDAP to LDAPS. LDAP works fine.
We have ports 389 and 636 open on our FortiGate firewall. After inputting our local CA certificate and clicking Test we get a Network error message at the top.
We are using the local CA certificate from our Windows server 2019 domain controller/Certificate authority by exporting it in DER format. We have also tried that same domain controller server certificate, which is what EMS is syncing with today.
Any thoughts about what could be doing wrong? Could it be the certificate export process or maybe something else?
