3.2.2.1 Proxy Authentication

OmniPortlet supports proxy authentication, including support for global proxy authentication and authentication for each user. You can specify whether all users will automatically log in using a user name and password you provide, each user will log in using an individual user name and password, or all users will log in using a specified user name and password. If the OmniPortlet provider has been set up to use proxy authentication that requires your login, a Proxy Authentication section displays on the Source tab where you can enter this information. The Proxy Authentication section only displays for the data sources that may require you to use a proxy server to access them: CSV character-separated values, XML, Web Service, and Web Page.
