We have an application that requires Kerberos authentication. A script can be recorded pretty easily but the playback has proven to be problematic.

We have LoadRunner 9.52 and is updated with all patches

Things that I have tried, in various combinations:
The Integrated Authentication switch set to Yes
Disable NTLM2 session security set to Yes
WinInet replay instead of Sockets

I have had an engineer provide me a krb5.ini file and set up the environment variable KRB5_CONFIG=C:\WINNT to point to it.

Any help or suggestions would be appreciated.
