When will the fix for the issue connecting to DS over SSL using LdapSessionOptions on Linux be released?

[rafeeqg]

On Linux, we're having issues connecting to OID using LdapSessionOptions via SSL. I've been keeping an eye on MR #52904, but that does not appear to be included in the current runtime version 5.0.3. Could you please tell us when this fix will be ready and in which version?

Code

public string Connect()
        {
            var identifier = new LdapDirectoryIdentifier("xxx.xxxx.com", _securePortNumber, true, false);
            var connection = new LdapConnection(identifier)
            {
                AuthType = AuthType.Basic
            };
            connection.SessionOptions.ProtocolVersion = 3;

            var credential = new NetworkCredential("xxxx", "xxxx");
            connection.Credential = credential;

            try
            {
                connection.SessionOptions.SecureSocketLayer = true;
                connection.SessionOptions.VerifyServerCertificate = new VerifyServerCertificateCallback((connection, certificate) => true);
                connection.Bind();
            }
            catch (LdapException ex)
            {
                Console.WriteLine(ex);
            }
            return "Success!";
        }

It won't be in the 5.0.x packages at all, it's a feature for 6.0.0. I believe it should be present in the 6.0.0-preview.6 version of the package.

Thanks @bartonjs. I'll mark this as answer
