How to get the calling username in a DCOM object ?

[Bart9140]

Hi,

We want to know how we can identify the user(s) who creates an instance of our class on the server
(so user1 on a client creates an instance of an object on our server, how do we know on the server that it was user1
).

This way we can do our own security if we want to get information on our legacy systems.

Thanks a lot !

Howdy,

In VB:

In a MTS enabled class:

Public property Get OriginalUsername() As String
Dim objCtx As ObjectContext
Set objCtx = GetObjectContext()
OriginalUsername = objCtx.Security.GetOriginalCallerName
Set objCtx = Nothing
End Property

Greetz,
