I have:

  • a service running under user account domainA\userA on hostA from domainA
  • SPNs created for the service running on hostA for user account domainA\userA
  • a client part of my application is trying to access resources (through remoting) from the service running on hostA
  • but this client part is running on hostB from domainB and under the user account domainB\userB
  • appropriate delegation settings are done for user account domainA\userA

    • trusted for delegation
    • SPNs set properly with no duplicates
    • domainA and domainB have two way trust

I get this error:

  • A secuity package specific error occured: Unspecified error (0x80004005)

Could you please see if there is any authentication setting I missed?
