Support Client-Side Sorting

OpenLDAP is the only supported LDAP directory that does not support server-side sorting. Instead, OpenLDAP requires that all sorting be performed on the client side. To accomplish this, all XPS objects are retrieved at start-up using server-side paging.

To support client-side sorting, the OpenLDAP directory administrator must configure the following settings in the slapd.conf file:

• Enable reading of the Root DSE.

  This setting allows the XPS client to read the OpenLDAP directory's type and capabilities.

• Set the maximum number of entries that can be returned from a search operation >= 500.

  This setting accommodates XPS objects which are retrieved in increments of 500 by server-side paging.

• Allow a simple V2 bind.

  This setting allows smconsole to test the LDAP connection using a simple V2 bind.

To support client-side sorting

1. Add the following lines to the slapd.conf file:

   access to *
   by users read
   by anonymous read
   access to dn.base=ACL by users read
   

   • ACL

     Specifies an access control list or list of permissions.

   Note: For more information on how to specify the ACL, see http://www.openldap.org/doc/admin24/access-control.html.

2. Verify that the value specified by the sizelimit directive in the slapd.conf file >= 500:

   sizelimit 500
   

   Note: The default sizelimit value is 500. For more information, see http://www.openldap.org/doc/admin24/slapdconfig.html.

3. Add the following line to the slapd.conf file:

   allow bind_v2
   

The slapd.conf file is configured to support client-side sorting.
