QaaWS SSO (Pre-authentication information was invalid)

$

Hi All,

 

In our SAP BO BI 4.0 SP04 Patch 4 platform on Windows we have configured SSO for web services clients as is described in this note:

 

1646920 - How to configure Web Services Single Sign-On (dswsbobje) with Tomcat for SAP BusinessObjects Business

Intelligence platform 4+

 

We have review again and again this configuration and all seem to be ok, but it doesn't work.

 

We obtain this message from server:

 

"login excepción (error: FWM00006). Pre-authentication information was invalid (24)"

 

First I have to say that we have correctly configured SSO with BI Launch pad.

 

We have read stdout.log Tomcat file and this is what we see:

[Krb5LoginModule] user entered username: SKMADTCSAP14$

[Krb5LoginModule] authentication failed Pre-authentication information was invalid (24)

This also what we see when analize kerberos protocol whith Wireshark.

It has sense for me if the user is SKMADTCSAP14$. It shows a credentials error because it is not my AD user. I think it must be???. SKMADTCSAP14 is our host name.

I don't understand why don't it uses my user for preauthentication. How does Tomcat get this user?. What did we do wrong?.

Thanks in advance,

Carlos Castrillón
