Portal is timing out freequently and giving "User authentication failed for user: USER.PRIVATE_DATASOURCE.un:Guest. Messages will not be delivered! in the traces"

[Former Member]

Hi All,

Users are facing runtime error in the portal more freequently but respective exception id not recorded in the portal logs. When user click again in the navigation they are getting no portal view available "Page not found. Refresh the page and try again later"  message.  Not able to navigate and had to relogin again to the portal. When checking in the default traces i see lot of "User authentication failed for user: USER.PRIVATE_DATASOURCE.un:Guest. Messages will not be delivered! in the traces" messages. Not sure this error is related to the runtime error users getting at the time. Please let me know if you have any idea on this issue.

Thanks,

Shyam.

Hi,

What version and SP are you using?

Where exactly the error occurs? Is it displayed instead of the whole portal page after login? Does it happen after navigating to specific application? What exactly the scenario is?

Is there any stack trace with the error from the trace? The stack traces in the default trace that are related to the error, can help detecting whether there is a problem in a specific application.

Are you using UWL or RTMF? You can see if the RTMF is running by performing HTTPWatch trace – you will see many pooling calls of RTMF (in the past there was an issue with this application).

Thanks & regards,

Hi Michal.

We are 7.3 SP8.

Error is coming in the content area and other navigations are not working. When refreshed the browser its going to logon page.

I can see RTMF related errors

Hi Shyam,

From the exception that you are getting, the issue seems to be with the authentication of user: guest.

"com.sap.netweaver.rtmf.getUserMessages.getUserMessages [Thread[HTTP Worker [@186971543],5,Dedicated_Application_Thread]] Fatal: User authentication failed for user: USER.PRIVATE_DATASOURCE.un:Guest. Messages will not be delivered!"

Users are accessing the webdynpro applications are and when switching to other navigation users are getting this error.

Is this exception occurring for all users? If yes, then there can be two possibilities:

1. When users switch from WD applications to other navigations as described by you, the user details are replaced by an anonymous user. In this case, you need to check how users are navigating and check user mappings or role mappings.

2. If the issue is only with specific users (Anonymous), then you need to check the Auth Scheme set for each object and set it to anonymous.

Do let me know in case you have any questions.

Best Regards,
