SSO between R/3 and Web Server Filter is not working

Hi all,

I have to configure SSO to access from SAP R/3 to a third-party web application through Web Server Filter.

R/3  WSF  3rdParty App

I think everything is configured properly, but when I issue the http request from R/3 to WSF I get the following error in sapsso.log file in apache server:

======================================================

trc file: "/usr/local/app/apache/sapsso.log", trc level: 3, release: "620"

And in the error_log file of the apache http server there’s the following:

It seems like there isn’t the date in the ticket issued by SAP R/3. However, I tried to configure sso between the same R/3 server and an EP and worked fine.

I also tried to decrypt the ticket issued by R/3 but I get a segmentation fault.

Does anyone can help me?

Thanks in advance.
