The Query objects defined in the directory abstraction layer let you predefine LDAP searches that you can then execute from a workflow form. The information in this section illustrates how you can define a query and use it in a form.
Suppose that you want to distribute calling cards to certain employees, but you only want to distribute calling cards to employees who work at home, and whose homes are located outside of the local office’s area code. You create a workflow form that allows the employee to:
Verify that they qualify to receive a card.
Submit a request for a card if they do qualify.
On your form, you allow users to enter the area code of their own local office and based on that area code, review a list of users that qualify for a card. The runtime form is shown in Figure 6-33.
