TicketExpired with valid certificate

Hi folks,

using the "Enabling Single Sign-On from SAP J2EE Engine/EP to Non-SAP Java Applications" from Tim and Stephan we get a ticket, but every time we try to connect we get a TicketExpired exception:

Caused by: com.sap.security.api.ticket.TicketExpiredException: Ticket not valid until Wed Dec 01 15:06:00 MET 2004

at com.sap.security.core.ticket.imp.Ticket.verify(Ticket.java:936)

Portal certificate is valid till 2009.

Lifetime of Portal ticket is set to 8h.

Version Portal: EP 60SP2P4 -

Version Engine: J2EE 620PL25

Connecting to tomcat5.0.27 using the war-file from Stephan and Tim.

Any ideas?

Many thanks,

Mathias
