IBM Traveler 22.214.171.124 enabled by default a feature that allows Traveler to “Run as a User” instead of as a server. This feature resolves several long standing issues with accessing the user’s data as the server ID.
The last point above may cause sync issues for mobile users. If the access controls are inadvertently set to values that restrict individual users, but do not restrict the Traveler server, then users that could sync when running as the Traveler server ID might not be able to sync when running as their user ID.
Note that the Traveler administrator can disable the Run as User feature by setting the notes.ini value NTS_USER_SESSION=false on all Traveler servers and restarting the servers. This may be a quick way of restoring sync capability to the few affected mobile users with restrictive access control settings. However, it is not recommended because it is a global setting, so all users will lose the benefits of Run as User when it is disabled.
