Configuring Application Source Qualifier Properties

Configuring Application Source Qualifier Properties

Configure the Application Source Qualifier properties for an LDAP source on the LDAP Properties tab.

The following table describes the LDAP properties for LDAP sources:

Property	Description
Source Filter	Configure a filter condition to query for the LDAP entries. Use the standard LDAP syntax for filter expressions. For example, “(&(sn=Geisel)(mail=*))” Default is blank. You can include parameters and variables in a filter condition. The PowerCenter Integration Service handles parameters and variables in the following order: Predefined server variables Mapping parameters and variables Workflow variables Session parameters
Search Level	Limits the scope of search performed on the directory data. You can use the following search levels: Base. The PowerCenter Integration Service performs the search operation on the base DN. One Level. The PowerCenter Integration Service performs the search operation on the entries that are one level below the base DN. SubTree Level. The PowerCenter Integration Service performs the search operation on the entire SubTree of the base DN. Default is SubTree Level.
Include Object classes in filter	Includes the selected object classes in the LDAP filter when the queries are executed. Select this option to retrieve the entries that belong to all the selected object classes. Disable this option to retrieve entries regardless of their object class.
Server Side Sorting	Determines whether the server-side sorting is enabled and critical. You can use the following server-side sorting options: No. The unsorted data is displayed. Yes. If the server supports sorting, the sorted data is displayed. If the server does not support sorting, the unsorted data is displayed. Critical. If the server supports sorting, the sorted data is displayed. If the server does not support sorting, the PowerCenter Integration Service does not perform the search operation and returns an error. Default is No.
Sorted Ports	List of ports selected for server-side sorting. The selected ports appear as a comma-separated list of attributes that are used for server-side sorting. Default is blank.
Dereference Aliases	Indicates how the PowerCenter Integration Service dereference aliases during the search operations. You can select the following options to dereference aliases: Always. Always dereference aliases. Never. Never dereference aliases. Finding. Dereference aliases when you locate the target entry. Searching. Dereference aliases after you locate the target entry. Default is Always.
Follow Referrals	Specify whether you want to automatically follows referrals. The following options determine how to follow referrals: Ignore. Ignores referrals. Follow. Follows referrals automatically. Throw. Follows referrals if the PowerCenter Integration Service successfully binds the entries to the referred directory server with supplied credentials. If the PowerCenter Integration Service does not successfully bind the entries to the referred directory server, it writes a non-fatal error into the session log. When the PowerCenter Integration Service extracts data from an LDAP source, it counts the errors encountered during resolving the referral entry. The PowerCenter Integration Service fails the session when the error count reaches the error threshold. Default is Ignore. For the Follow and Throw options, the dn attribute value is modified from the URL format to the simple format by removing the protocol and the referred directory server details. For example, “ldap://ldapserver:389/cn=refEntry,o=airius.com,cn=testref2,o=airius.com” is modified to the simple format “cn=refEntry,o=airius.com,cn=testref2,o=airius.com”.
Maximum Entries	Maximum number of entries to be returned as a result of the search. If the value is 0, the PowerCenter Integration Service returns all the entries. The Count Limit session attribute overrides the Maximum Entries value. Default is 0.
Maximum Search Time	Maximum time in milliseconds to wait for the search results. A value of 0 indicates that there is no maximum time limit. The Time Limit session attribute overrides the Maximum Search Time value. Default is 0.
Page Size	Size of the page set to retrieve the maximum number of entries for each page. A value of 0 indicates that all the entries are retrieved in one page. Default is 0.
