Using Results Paging

In order to cope with entries containing multiple sub-entries, LDAP Administrator enables you to display their sub-entries paged.

To select a paging mode for an entry:

Select an entry under which you'd like to enable result paging.
It is recommended you use the Manual Mode to browse directories containing large entries in order to prevent automatic fetching of results without any paging mode applied.
Open the Properties page for the currently selected entry by clicking the Properties button on the Standard toolbar.
Select the Paging Policy page.
Choose a paging mode from the Mode box.

Adjusting Paging Mode Parameters

Each paging mode has its own specific parameters used to assist in adjusting the browsing behavior.

Simple Page Mode

For this mode you are expected to specify the number of entries to be fetched per each page for cases when you click the Next Page item. To set size for a page, type a number in the Page Size box.

Plain VLV Mode

This mode requires specifying a range of entries to fetch. Use the Range Trackbar control to specify the desired range with either your mouse or the Left and Right arrow keys. Keep Shift pressed to extend the range.

If you don't have any paging modes applied for a currently selected entry yet, it is impossible to get to know how many sub-entries the entry contains, so LDAP Administrator will assume this amount is 100 sub-entries for you to set a display range using the percentage scale. As soon as you have performed at least one search with the paging mode enabled, the total number of entries will be adjusted.

Framed VLV Mode

For this mode you can specify the number of entries to be displayed on screen at a time and the number of elements to scroll upon clicking the Up and Down items. Enter the desired numbers in the Page Size box for entries per page and in the Step Size box - for elements to scroll.

Cumulative VLV Mode

This mode enables you to specify the number of entries to be fetched for each page upon clicking the More item. Type the desired number in the Page Size box to set the amount of entries to be fetched in one request.

Transparent Mode

This mode requires setting the Page Size parameter, which determines the maximum number of subentries returned upon each subquery used by this mode. It is important that the specified parameter value should not exceed the server side limit (if enabled), so to be able to return a complete set of subentries.

Since paging mode parameters are considered to be profile settings, they'll get reset if originally specified for one or more sub-entries of an entry having been refreshed.

Specifying Sort Keys

By checking the Enable server-side sorting box, you can specify sort keys to be used on the server side for sorting subentries before processing each of the paging requests. At least one sort key must be set for the VLV modes to function properly despite the fact that sort keys in general are known to slow down the overall performance. Here is what a sort key consists of:

Sort Key. An LDAP attribute name to be used as a sort key.
Matching Rule. The object identifier (OID) or name of a matching rule for sorting.
Sort Order. Sets the sort order to be from lowest to highest or vice versa.

You can specify multiple sort keys. Use the Paging Policy page to add new, edit, remove and reorder sort keys. It's recommended you move your preferred sort keys to the top because a server processes them from top to bottom. To add a new sort key, click the Add button. To edit parameters of an existing sort key, select one and click Edit. To remove a sort key, select one and click Remove.

When applying the VLV results paging mode, you'll need to specify at least one sort key.
