IWMSAuthenticationContext.GetImpersonationAccountName (C#)

The server calls the GetImpersonationAccountName method to retrieve the name of the Windows 2000 security user or group account that the authentication context simulates if authentication succeeds.

Syntax

Parameters

This method takes no parameters.

Return Values

This method returns a string containing the account name.

Remarks

To impersonate a logged on user, a plug-in must retrieve a token that represents the user. How you do this depends on the authentication protocol that your plug-in is designed to implement. For example, a Digest Authentication plug-in can use the System.Security.Principal.WindowsIdentity.Impersonate method of the Microsoft® Windows® .NET Framework.

Example Code

public string GetImpersonationAccountName()
{
    WindowsImpersonationContext ImpContext;
    string strIdentity;

    try
    {
        ImpContext = WindowsIdentity.Impersonate(m_hToken);
        strIdentity = WindowsIdentity.GetCurrent().Name;
        ImpContext.Undo();
        return strIdentity;
    }
    catch(Exception e)
    {
        // TODO: Handle exceptions.
        return "";
    }
}
