Question

Hi all!
When i try to logon in the EP 5.0, the message
Your session has expired. Please close your browser and log on again. appears.
The verify.der certificate has expired.
I´ve removed verify.* and ticketKeyStore files and restarted IIS, but the certificate has not been generated
Do you know how to re-generate it? Is a Productive system and it is so urgent!

Hi,
What's small and useful, but often doesn't last as long as you want? 
    1.      Start the SAP J2EE Engine Administrator with <PORTAL_DIRECTORY>admingo.bat.
       2.      Connect to the portal server.
       3.      Choose <SID>/Server<…>/Services/Key storage from the tree.
       4.      Select the view TicketKeystore under Views.
       5 . generate a portal certificate
       6.      Under Entry, choose Create.
Enter the following values in Key and Certificate Generation:
&#61601;        Subject properties: Every key has to have a value under Value.
The value CN=Common Name is displayed as the owner in transaction STRUSTSSO2 and serves to identify the certificate. SAP recommends that you use <HOSTNAME_PORT> from the portal server.
&#61601;        Entry name: SAPLogonTicketKeypair (the entry SAPLogonTicketKeypair-cert is generated automatically)
&#61601;        Store certificate: X
&#61601;        Algorithm: DSA
       7.      Choose Generate to generate the certificate.
       8.      Highlight SAPLogonTicketKeypair-cert under Entries.
       9.      Under Entry, choose Export.
   10.      Export the portal certificate as <PORTAL_SID>_certificate.crt in file format X.509 Certificate (*.crt).
