help: Host Authentication Failed

[Zhenlong Hou]

Hello everyone

I want to use Windows client/server + MIT Kerberos & OpenLadp to implement SSO authentication.
On the application server side, I use LsaLogonUser() to ask for a Network style logon through S4U Kerb extension.
But the LsaLogonUser() failed.
According to the KDC Server's log, there is a error "LOOKING_UP_SERVER: authtime 0, host/sample.com at SAMPLE.COM for host\/sample.com at SAMPLE.COM, Server not found in Kerberos database" in TGS_REQ.
According to the application server's log, the sname-string is 1 item and SNameString is host/sample.com in req-body of tgs-req.
I think the sname-string should be 2 items and SNameString are host and sample.com.

My question is the S4U in windows can't implement SSO authentication with MIT Kerberos & OpenLadp?
Or I mistaken about some configuration on Windows side or on MIT Kerberos & OpenLadp side?

Thanks in advance
Chris
