Login errors in V3 when using Kerberos authentication

[Wessel, Keith]

Hi,

I'm using the default authn flow and Kerberos authentication. I have a fairly customized login.vm, but I left the code in place for display login errors above the login form. I'm trying to figure out what needs to be added to the template or, better yet, the properties to have a nice error message for incorrect username/password. Right now, I get:

Login Failure: Pre-authentication information was invalid (24)

Not really helpful to your average user. How do I turn this into something more user-friendly?

Thanks,
Keith
