You can use the Entrust Certificate Services (ECS) portal to generate LDAPS TLS certificates for each domain. Follow the steps in Generating a PKCS #12 and select the following values.

Setting

Value for LDAPS TLS certificates

​Certificate Authority

Select the issuing CA described in Creating an Entrust-hosted Certificate Enrollment Gateway for WSTEP.​​

Certificate Profile

Select the multiuse-p12-key-encipherment-client-server certificate profile described in Multiuse certificate profiles.

Subject DN

Enter a CN matching the FQDN of the Domain Controller (for example: dc.example.com).

Certificate Expiry

Enter a period not exceeding 397 days.

Subject Alternate Names

All Subject Alternative Names must include a DNS matching the FQDN of the Domain Controller.

If you generate the LDAPS TLS certificates with a non-ECS authority, ensure they are SHA-2, as SHA-1 certificates are not allowed due to their vulnerabilities.
