Hello @escarre,
this is from the OPC Labs tech support.

What is it that you are trying to achieve?
The URL of the server is specified in method calls, sometimes directly, sometimes in the endpoint descriptor object. But I am not sure if that was your question.

Best regards

Hi m.baumgartner,

I'm a Delphi developer and I'm trying to set up the user and password information.

I saw you used TEasyUAClientConfiguration, but how do you set the URL server information?

Thanks,
Escarre

This is an interesting idea (setting multiple identities globally). I will make a note for a possible product enhancement. Currently it is not supported.

But, having something like this would probably require a trial-and-error approach: The component will have to simply try each of the identities provided, sequentially, to figure out which one works. And it will receive an error when the identity is not the right one. This would slow down the connections. For this reason, aside from some special cases, I do not see it as a truly "good" thing to have.

Best regards

Hello,
Thanks for your reply.
Yes this will work with editing the UAENdPointDescriptor.
I was hoping a possibility to set multiple useridentity globally to simplify the coding.

Thanks anyway for this solution that will perfectly work.

Best Regards.

The user identity can either be set globally (the way you are doing it), or it can be specified inside the UAEndpointDescriptor: www.opclabs.com/files/onlinedocs/QuickOpc/Latest/User%27s%20...ntDescriptor~UserIdentity.html .

So, you just need to create the UAEndpointDescriptor, set its "usual" properties (opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User's...ointDescriptor_properties.html ) like the UrlString, and then also set the UserIdentity. This can be done differently for each server then.

Best regards

UA Authentication was created by m.baumgartner
Hello,
We use QuickOPC in COM with Delphi.
I try to connect to OPC server UA with authentication.
With this code it works great :
EasyUAClientConfiguration := TEasyUAClientConfiguration.Create(nil);
  //EasyUAClientConfiguration.AdaptableParameters.SessionParameters.UserIdentity.UserNameTokenInfo.UserName := 'admin';
  //EasyUAClientConfiguration.AdaptableParameters.SessionParameters.UserIdentity.UserNameTokenInfo.Password := 'moxa';  UserIdentity := TUserIdentity.Create(nil);
  UserIdentity.UserNameTokenInfo.UserName := 'admin';
  Useridentity.UserNameTokenInfo.Password := 'moxa';
  EasyUAClientConfiguration.AdaptableParameters.SessionParameters.UserIdentity := Useridentity.DefaultInterface;
  Useridentity.Destroy;  EasyUAClientConfiguration.Destroy;
But know i want to pu multiple Username ant password for multiple OPC Server UA.
How we must do that in Delphi? I have found UserIdentity.CreateUserNameIdentity in your documentation but this method is not available in Delphi wrapper.

Thanks for your help.
