NWA - User ID & Pass problems

Question

Hello,
I have tried to log on at SAP Netweaver Administrator but it is impossible.
I know that I am using the correct user id and pass because I have worked with NWA some days ago.
I can logon in Portal options 'System Information' and 'Web Services Navigator' with the same user but when I try to logon in 'SAP Netweaver Administrator' or 'User Management' it does not work. Also, I can to access to J2EE Engine Visual Administrator with the same user.
Additionaly, when I try to logon with that user and pass, the message 'User authentication failed' does not appear. That's indicates it is the correct user id and pass but it does not work.
I remember that, in the last changes, I deleted the entries in the TicketKeyStore (J2EE Engine Visual Administrator --> NWP --> Server --> Services --> Key Storage) Could it be the problem?
Please, anybody can help me?
I am looking forward to hearing from you as soon as possible.
Best regards,

Hello,
Finally, the problem is solved.
I have configured the certificates in the Ticket KeyStore, that's the quid!!. I used 'DiagTool' tool for review log files and solve the problem. It's very useful and interesting tool...
To create a correct Portal Certificate:
    1.1 Log in to the Visual Administrator
    1.2 Choose Server --> Services --> KeyStorage --> TicketKeystore
    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  (just example)
        c. Entry Name: SAPLogonTicketKeypair
        d. Store Certificate: Mark it
        e. Key Length: 1024
        f. Algorithm: DSA
        g. Press Generate
Now you will have two entries in the TicketKeyStore:SAPLogonTicketKeypair and SAPLogonTicketKeypair-cert
If anybody have the same problem, I recomend to review the Ticket KeyStoore (Visual Administrator) and user 'Diagtool' tool.
Thank you all.
