LoadRunner9.5 and Kerberos Authentication

I am able to successfully record an application which has Kerberos authentication enabled. On replay I get the following error:

Action.c(235): Error -26630: HTTP Status-Code=401 (Unauthorized) for "http://*******.com:8001/XXX//xxx/amf" [MsgId: MERR-26630]

Action.c(235): flex_web_request("amf") highest severity level was "ERROR", 1518 body bytes, 167 header bytes [MsgId: MMSG-26388]
Ending action Action.


I have already given the required credentials using web_set_user. I have also made Yes the "Enable Integrated Authentication". Have also also tried the "WinInet replay instead of sockets" and alternately the web_set_sockets_option also.

Still getting this error. Will saving the krb5.ini file to my local system help resolve this. I guess that this file has a default realm specified in it.

Please help.

Thanks,
