1.6. Generating Links Between Entry Attributes
Linking attributes allows Directory Server to express and maintain relationships between entries
dynamically. T he Linked Attribute Plug-in uses the DN value of an attribute to trace its way to the related
entry, and then it adds a reciprocal value on that entry. T his is similar to the way that classes of service
dynamically generate values from a template entry, only no template is necessary.
For example, a manager and his direct report have a relationship. Whenever the Directory Manager adds
a manager attribute to a user entry, the Linked Attributes Plug-in follows that DN to the relate entry, and
then adds a directReport attribute to the manager's user entry.
1.7. Validating Attribute Syntax
Syntax validation verifies that the value given for an attribute matches the required syntax for that
attribute. If the value is of the wrong syntax, then the modify operation fails.
New scripts have been added to validate the syntax of existing attributes.
1.8. Added Support for Dereferencing Searches
A dereferencing search is a quick way to track back over cross-references in an entry and return
information about the referenced entry. Dereferencing simplifies many client operations. Some
operations may require getting a list of cross-links from one entry and then performing a second series
of searches to get information from the entries referenced in the list. Dereferencing allows those
sequences of searches to be consolidated into a single search.
Directory Server 8.2 now supports the dereferencing control for search operations. When the
dereferencing control and search information is passed with a search, Directory Server can perform the
series of searches required.
IMPORTANT
The dereferencing searches are not done using MozLDAP command-line tools. T he server
supports dereferencing search operations; however, the client tools with Red Hat Directory
Server do not. T herefore, dereferencing operations must be done using OpenLDAP command-line
tools version 2.4.18 or later or other clients which support dereferencing searches.
1.9. Added Support for Bitwise Filters
Directory Server 8.2 introduces support for searching for attributes with bit field values, both for bitwise
AND and bitwise OR searches.
Bit field values are common in Windows attributes. Search support for bitwise attribute values helps
integration between Red Hat Directory Server, Red Hat Enterprise Linux, and Windows-related
applications, such as Samba file servers.
1.10. Enhanced Searches for Simple Paged Results
Simple paged results is a control that breaks search results into pages of a certain length. In Directory
Server 8.2, this is implemented as a supportedControl. Much like virtual list views, simple paged
results parcel very large search results into manageable sizes. Simple paged results can be scrolled
through; the full behavior of the control is described in RFC 2696.
