Specifying Web Server Authentication
PTC has provided several methods (Ant scripts) to improve and simplify the configuration of the PTC HTTP Server for Windchill. A commonly used script is the webAppConfig.xml Ant script. For example, it is used by the installers (along with config.xml) to perform the configuration of PTC HTTP Server’s management of the Windchill Web application. Other webAppConfig.xml uses include:
Manages the generation (and regeneration) of the app-<Web application>-Auth.conf and app-<Web application>.conf files. These files contain the authentication parameters for the Windchill products. They are reproduced in their entirety each time an update occurs, thus, manual changes applied to the files are lost.
Ensures that the Web application settings that apply to the Windchill system are applied to all the entries in the app-<Web application>-Auth.conf file.
During the update, the webAppConfig.xml script retains the existing data in the file while it applies the new changes saving you the effort of entering the data that already exists.
The following sub-sections provide instructions to implement various Windchill authentication strategies using the webAppConfig.xml Ant script.
