Key under alias [SAPLogonTicketKeypair] cannot be retrieved from keystore view [TicketKeystore]. Authentication stack: [sap.com/com.sap.lcr*sld]. The default kestore view is [TicketKeystore]. The default keypair alias is [SAPLogonTicketKeypair]. Check the login module options and UME properties.
I see this in the Netweaver Administrator log viewer of an SAP PI 7.1 system after I have configured SSO (as per http://help.sap.com/saphelp_nwpi71/helpdata/en/32/1c1041a0f6f16fe10000000a1550b0/frameset.htm)
Please can you explain why am I getting that error and how I can resolve it?
