Hi, I am having trouble getting the new MSOLEDBSQL19 driver (v19.2.0.0) to work with PowerBuilder2022 build 1892.
I generated a self-signed certificate for SQL Server 2019 using the PowerShell script provided at the bottom of this page: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/configure-sql-server-encryption?view=sql-server-ver15

In SQL Server Configuration Manager, I forced the ForceEncryption option to TRUE, and selected my self-signed certificate. And after that, I restarted the SQL service successfully.

Then I exported the certificate and installed it on my computer.
When I try to set up the database in PowerBuilder, I get the following error message:

(SSL Provider: The target principal name is incorrect)

I don't understand what I missed or what more needs to be done.
Here is the database connection syntax:
// Profile MyDataBase
SQLCA.DBMS = "MSOLEDBSQL SQL Server
SQLCA.ServerName = "MYSERVER\SQL2019"
SQLCA.AutoCommit = False
SQLCA.DBParm = "TrustedConnection=1,Database='MyDataBase',Encrypt=1,TrustServerCertificate=1,Provider='MSOLEDBSQL19'"

If I use the old MSOLEDBSQL driver (v18.6.4.0) it works.

Hello, I managed to solve my problem by creating a new self-signed certificate by putting several names for my server in the powershell command.

New-SelfSignedCertificate -Type SSLServerAuthentication -Subject "CN=MYSERVER.domain.com" `
-DnsName 'MYSERVER','MYSERVER.domain.com','localhost' `
-KeyAlgorithm "RSA" -KeyLength 2048 -HashAlgorithm "SHA256" -TextExtension "2.5.29.37={text}1.3.6.1.5.5.7.3.1" `
-NotAfter (Get-Date).AddMonths(36) -KeySpec KeyExchange -Provider "Microsoft RSA SChannel Cryptographic Provider" `
-CertStoreLocation "cert:\LocalMachine\My"

Hi Christophe,

For the TrustServerCertificate issue, it is related to the OLE DB driver 19, please note the application settings never reduce the level of security set in the registry, please refer to the article below for details.
https://docs.microsoft.com/en-us/sql/connect/oledb/features/encryption-and-certificate-validation?view=sql-server-ver16

There are two solutions for this issue:
1. Refer to the above article to change {base_registry_key}\Flag2 from 0 to 1, please try restart machine after registry changed.
2. Refer to the article below to install a valid certificate on SQL Server and set SQLCA.ServerName to use a valid domain name that matches the certificate.
https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/manage-certificates?view=sql-server-ver16

Regards,
Kai

Are you sure that the server name in the certificate and what you put in sqlca.ServerName are the same?

Hello, in sqlca.ServerName i have the name of the sql server instance (MyServer\SQL2019) and in the certificate i just have the name of the server (MyServer).

I don't know if this will work but you could try creating the certificate with MyServer\SQL2019 as the server name.
