Has anyone seen this before, and knows a solution?
Thanks in advance,
* IIS website listens on port 42 (not the usual port 80)
* IE 8 Client asks for a ticket and gets it for HTTP/servername.domainname.
* Client sends ticket to IIS.
* Server responds with errorcode: KRB5KRBAPERRMODIFIED and Server Name (Service and Host): host/servername.domainname
To me, it seems that IE is sending a ticket for the HTTP spn, but the server / IIS wants a ticket to the host spn. Is there a way to make IIS change it's mind?
