When documents are retrieved from OnBase through the document library with DocPop, OnBase uses the authentication method specified for DocPop in the OnBase Web Server's Web.config file. If the OnBase document is retrieved through a library that is a Web Part on a page that includes OnBase Web Parts, the DocPop authentication method is overridden by the method used by the OnBase Web Parts. For example, if the Web Parts are configured for Active Directory authentication, then DocPop will attempt to use Active Directory authentication regardless of the DocPop settings in the Web Server's Web.config.
