To see or modify working examples of UI handler properties, explore the UIHandlers.xml file located in the \eGuide\WEB-INF\plugins\eGuide directory.
Although most UI handlers must be selected only from the Administration utility, the advanced properties section contains useful configuration settings.
These advanced settings are specific to each UI handler's Data handler. Data handlers are beyond the scope of this document, but you don't always need to understand Data handlers to use their features. The basic idea is that each UI handler has a corresponding Data handler. The Data handler knows how to store and retrieve information to the LDAP data source. The advanced properties section allows administrators to change some of the storing and retrieving behaviors.
For example, you might want to apply a different set of attributes to your LDAP DN display. These Abstracted attributes are stored on the object that the DN specifies (not on the object where the DN attribute is located); therefore, you must specify the attributes for which eGuide should do an additional read, in order to display the attributes.
