Set up File Synchronization
The publisher must first be configured to use file synchronization. See File Synchronization for details. When file synchronization is enabled, the property useworkerdownload is set to the location of an authentication file, auth.properties (refer to Step 2 of the previous section). This file must have a default username and password for all the publishers that use file synchronization. The following is the syntax for defining these defaults:
auth=<worker username>:<worker password>
For Distributed File Server Workers, the dedicated worker user account's username and password created previously must be added as a new property in the authentication file auth.properties. This new property includes the site name and authoring application in the following syntax:
auth.<Site Name>.<Authoring Application>=<worker
username>:<worker password>
For example, a Distributed File Server Worker is set up to publish Creo Parametric files that reside on the file server at site "RemoteSiteA". A dedicated Windchill user account "WorkerAUserName" with password "WorkerAPassword" has been set up, with its Preferred File Server preference set to "RemoteSiteA." In this case, the following property would be added to auth.properties:
auth.RemoteSiteA.PROE=WorkerAUserName:WorkerAPassword
* 
Using auth.properties file entries like auth.RemoteSiteA.PROE is only supported in the context of Distributed File Server (DFS) Workers and must not be used for controlling the credentials used for non-DFS workers, for example, for different Authoring Applications.
