You can set it programmatically:

set package = ##class(%PackageDefinition).%OpenId("User",,.sc)
 
zw package
package=2@%Library.PackageDefinition  ; <OREF>
+----------------- general information ---------------

ERROR #743: CA certificate file is not valid [%OnValidateObject+97^Security.SSLConfigs.1:%SYS]

Turns out, Extension:basicConstraints field of the CA certificate must contain CA:TRUE. The BasicConstraints extension is intended primarily for CA certificates. It has a single Boolean variable, “cA”, which reflects whether or not the certificate is a CA certificate. If the certificate is a CA certificate, it can also declare a pathLen constraint that dictates how many sub-CAs are allowed to exist in the hierarchy of CAs.

To check:

Set bc=$System.Encryption.X509GetField(cer,"Extension:basicConstraints")
Write bc["CA:TRUE"
