But if I add Thread.CurrentPrincipal = null; between the deferrent impersonationsand then it works Since Thread.CurrentPrincipal uses lazy-loading, when it's first called, it will be populated from the impersonated identity (since it's null at first, Thread CurrentPrincipal Identity and TcpChannel (Page 1) - NET - Programmer's Town - Welcome to the Programmer's Town community forums.

The workflow does however need to get the name of the current user via Thread.CurrentPrincipal.Identity.Name This method gets called by Thread.CurrentPrincipal when the current principal is null. The System.Security.Principal namespace defines a principal object that represents the security context under which code is running. First let me say that this is not an Azure question, we are just using WCF services under IIS But most of the WIF expertise seems to be here so We have a security token handler We add it to the <securityTokenHandlers> section We have an http module implementing OnAuthenticateRequest. Please be careful that the GetClientCertificate method might return null if the client does not send an valid certificate Thread.CurrentPrincipal = new GenericPrincipal (new GenericIdentity (cert.Subject), new [] (HttpActionContext context).Setting HttpContext.Current.User ASP.NET Forums on Bytes 396,530 Members | 3,748 Online Join Now; (currSession[staywell.swprincipal] != null) return (MyPrincipal)currSession //System.Threading.Thread.CurrentPrincipal = principal; My customIdentity contains UserId, FullNam.

Due to some unfortunate mechanisms buried deep in ASP.NET, setting Thread.CurrentPrincipal in Web API web hosting is not enough When hosting in ASP.NET, Thread.CurrentPrincipal might get overridden with HttpContext.Current.User when creating new threads This means you have to set the principal. We often get questions about how to get the full name of the current user This wraps the GetUserNameEx API to return same Also shown is an alternate method using DirectoryServices with domain and username input parameters.
