Answer 1

Hi,
I faced the same problem when i am configuring the SSO,
check the portal client number in System Administration>System Configaration->UM Configuration--->Direct Editing
and give the same client number
In the dialog box that appears,
system ID :J2E
client :000
else check weather u r importing the certificate correctly.
First export the verify.der and and import that using the STRUSTSSO2
Thanks
