Validity of certificate with PSE type >WSPT for AT Communication

Hi,

today, when logging on to the SAP system (DEV and QAS), I got this warning message:

"Validity of certificate with PSE type >WSPT for AT Communication< ends in 2 days"

On STRUST, I have this problem:

I followed the procedure described in SAP note 1901250 on the document "Loading_Certificates.pdf" beginning at page 5, point 3 ("Go

to File and load the TEST Private Key PSE or PRODUCTION Private key Certificate PSE").

However, the expiring date is still 31.07.2014, so it didn't solve my problem.

Can you please let me know how to solve this?

thanks in advance

Antonio
