Hello,
we have a problem with our ASP.NET Application. If we open it in the Webbrowser, always a login dialog is shown, although e.g. the url is set as local intranet etc. In similar environments we don't have this problem. We checked now the traffic with fiddler and came to this output.
The first response of the server is that it returns Negotiate and NTL as WWW-Authentication.
Now our service returns Authorization: Negotiate TOKEN1 (TOKEN1 stands for a long kerberos token)
Server answers with 401 and WWW-Authenticate: Negotiate TOKEN2
The Client now ansers with Authorization: Negotiate TOKEN3
Again the Server returns 401 with WWW-Authenticate: Negotiate TOKEN4
Then the communication is finished.
We use Windows 2012R2 with built in IIS.
Can anybody help us with this problem. If you need further information I will send everything what is necessary.
Kind regards
Peter
