With EBO 3.2, the MD5 hash is disabled by default and when connecting using an EwsClient from SmartConnector Nuget package 2.4.36.0 i get the following error:
System.ServiceModel.Security.MessageSecurityException: 'The HTTP request is unauthorized with client authentication scheme 'Digest'. The authentication header received from the server was 'Digest realm="ews@SxWBM",qop="auth",algorithm="SHA-256",nonce="...
Should I be enabling MD5 in EBO (which works) or am i missing something when i create the EwsClient? Relevant snippets from my code below:
EwsServer EsSrv = new EwsServer()
{
UserName = "*******",
Password = "********",
EwsEndpoint = "http://192.168.68.200:88/EcoStruxure/DataExchange"
};
using (var ewsClient = CreateConnection(EsSrv))
{
GetAlarmEventsResponse activeAlarms = ewsClient.GetAlarmEvents(1, 3, "", null);
}
public class EwsServer
{
public string UserName { get; set; }
public string Password { get; set; }
public string EwsEndpoint { get; set; }
}
static EwsClient CreateConnection(EwsServer EsSrv)
{
var ewsSecurity = new EwsSecurity
{
UserName = EsSrv.UserName,
Password = EsSrv.Password
};
return new EwsClient(ewsSecurity, EsSrv.EwsEndpoint, EwsVersion.Ews12);
}

Hi Steve,
The MD5 setting (disabled or not) should have any influence on if this works or not!
I have just tested it locally, and it seems to work in either case.
Generally the error below is because the credentials are incorrect.. or the EBO server is out of Sockets.
I will reach out to you to debug.
Best Regards,
-Jeff
