Hi,

Your "ticket" authentication stack is slightly incorrect.

You need to swap position 2 and 3 so it looks like:

1. EvaluateTicketLoginModule   SUFFICENT
2. BasicpasswordLoginModule  REQUSITE

3. CreateTicketLoginModule   OPTIONAL

With your current configuration login tickets will never be created.

Make change via visual administrator security provider service.

If it still fails collect a webdiagtool trace from note 1045019 and attach the output and we can tell you exactly the issue if you wish.

Kind regards,
Cathal

Hello ,

I would suggest you to check couple of things.

1. Check if the java license certificate is valid.

2. Check if you find something in default trace at the time when the authentication fails in /nwa. Or else paste the log file here once you try to login into /nwa.

Regards,

Nirmal.

Hi Nirmal,

1. Check if the java license certificate is valid.  - VALID LICENSE is present in system.

2. Check if you find something in default trace at the time when the authentication fails in /nwa. Or else paste the log file here once you try to login into /nwa.

- default trace is not updated while logging to NWA, only security.2.log was updated as stated before.

Thanks

Hello,

Please check SAP note 1659382 and try to correct the login modules in Visual Admin.

Initially check point 1 and 2. If it still doesn't work then check proceed in the KBA.

Hope this helps.
