    Hi,

    the problem was the SPNEGO Template = 0

    To resolve the issue, open offlinecfgeditor

    in edit mode, go to security/configurations/ticket

    highlight the "template=spnego" key and delete it

    Restart the system and it Work !!

    best regards

    Hi, Steven

    What updates you performed?

    Try to restart your SAP system, it is possible that some applications do not run after upgrade.

    Best Regards,

    Aleh

    Hi,

    I had the similar issue after EHP upgrade on one of my NW 7.3 portal system. I followed the below recommendation (2) and it helped me to resolve the issue.

    RESOLUTION:

    1) Try to implement OSS Notes 1539483

    Alternatively you can follow this

    2) The most likely reason for this issue is that the core components are not deployed on the server correctly. Deploy the latest patch available for the core JAVA SCAs for: SAPJEE, SAPJEECOR, SAPJTECHF and SAPJTECHS and restart the instance.

    You will receive warning message when you attempt to login to ConfigTool saying your J2EE Core patch level is greater than JSPM patch level (something like this) and you can ignore that error.

    I hope this will definitely solve your problem.

    Best Regards,

    Vasanth G

    Thanks

    Hi Steve,

    I have opened the config tool in edit mode.. but I'm unable to find the template value .. under security/configurations/ticket !!

    I've just installed NW 7.3, I toom am not able to access the NWA page .. it says 500 internal server error. I'm able to access these pages from remote desktop or other servers..

    When I'm logged into the HOST in which NW 7.3 is installed it lets me open that start page, after that neither NWA or System info etc opens .. " 500 Internal Server Error "

    Can you help ...

    Hello,

    I had same problem.

    Using your workaround, it works. I can connect to my Prtal system.

    But, will spnego work after that?

    Do I need to do something on my spnego configuration to make it work?

    Regards
