                            <p:inputText id="employeeId" placeholder="Employee Id" required="true"
                                         requiredMessage="Employee Id is required"
                                         value="#{createAdminController.employeeId}"/>
                            <p:commandButton value="Search in VCN" update="ldapPanel @form"
                                             actionListener="#{createAdminController.searchInVCN}" id="searchButton"/>
                        </h:panelGroup>
                    </h:panelGrid>
                    <p:blockUI block="searchPanelGrid" trigger="searchButton">
                        <h:graphicImage library="images" name="loader.gif"/>
                    </p:blockUI>
