Problem Statement : When an user submits user id and password in the logon screen (i.e. NWA, Portal, System Info, etc.,), it doesn’t throw any error message, rather the logon page  is returned without any error message

Solution : Check the Existence, Validity and Consistency of the Certificate of Java Engine, if the certificate is invalid for some reason, recreate it and distribute it to the respective connected system (i.e. ABAP Stack). Below steps will guide you through the process.

1.1 Log in to the Visual Administrator
1.2 Choose Server --> Services --> KeyStorage --> TicketKeystore (Quick Tip: If you do not find TicketKeyStore in the list, then you are probably missing admin access, use the user which has Administrator rights)
1.3 Delete SAPLogonTicketKeypair-cert and SAPLogonTicketKeypair
1.4 Choose Create (Create button in the Entry field) and
type in the following information:
a. mark Store Certificate
b. Common Name: Your  (for example)

c. Entry Name: SAPLogonTicketKeypair

d. Store Certificate: Check It
e. Key Length: 1024
f. Algorithm: DSA
g. Press Generate

 

Now you will have two entries in the TicketKeyStore:
SAPLogonTicketKeypair
SAPLogonTicketKeypair-cert

Step 3 - Export the Portal certificate
3.1 Choose Server --> Services --> KeyStorage --> TicketKeystore

3.2 Choose SAPLogonTicketKeypair-cert and press Export (Export button in the Entry field)

a. Fill in a name of the Certificate
To keep track of your certificate, call it the SID of the Portal

b. Choose either X.509 or Base64 Encoded Format



Import the Downloaded Portal certificate to the Backend System Using STRUSTSSO2 transaction
