Hi Aravind,
no the verify.pse is a key-container for public keys. PSE is a container format comparable to P12 (PKCS12).
You can trace your call. If you use the verify.pse from the SAP portal then use the ssosamp as you did in in your 1st post, but set following environement variables before:
export SAP_EXT_TRC=/tmp/sso_trace.trc
export SAP_EXT_TRL=3
./ssosamp -i portalticket.txt -p verify.pse
-------
the portalticket.txt should come from Potal itself. In your 1st post use used the ticket from SAPSSOEXT SDK: So extract the MYSAPSSO2 cookie and place the value part into a file portalticket.txt.
After your call you should have a file /tmp/sso_trace.trc with all information about the validation.
regards,
