Solution - Problem 1
The problem typically occurs when a specific ADC Event takes a long time complete processing and send back a response to the scanner. The processing of the NLINK Event has to occur within the time specified in the "Synchronous Message Timeout" value. This setting is found in the NLINK Management Module (NMM) or NLINK Configuration Module (NCM) under the System Properties. By default it is set to be 60 seconds.
...
This value indicates the upper bound for the timeout if the Event does not complete. If the Event takes a lesser time to process, then the timeout will not be used.
Problem - Users sessions are getting terminated after some idle time
Users are getting terminated and reset back to logon page with error message. Message on logon page can vary
- Message on logon screen says "Your Session has expired[Status code 440]! Session Expired" message.
- Message on logon screen says "Error posting data [Page]: The request failed with HTTP status 401: Unauthorized.Status: Unauthorized"
- There can be corresponding entry in NLINK Event log "User 'XYZ' has been automatically logged off due to inactivity".
Solution

The NLINK ADC to SAP Solution will automatically log users off if there is no activity for a specified period of time. If this timeout is not managed and set properly, users can be logged-off sooner than they would like. There are 3 separate timeout values in the NLINK ADC to SAP Solution that need to be set properly. The first is set using NMM or NCM and the other two are set through Microsoft’s IIS Manager.
