Use an existing connection

Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined.

Note that when a Job contains the parent Job and the child Job, Component List presents only the connection components in the same Job level.

Host

LDAP Directory server IP address.

Port

Listening port number of server.

Base DN

Path to user's authorized tree leaf.

Protocol

Select the protocol type on the list.

LDAP : no encryption is used

LDAPS: secured LDAP. When this option is chosen, the Advanced CA check box appears. Once selected, the advanced mode allows you to specify the directory and the keystore password of the certificate file for storing a specific CA. However, you can still deactivate this certificate validation by selecting the Trust all certs check box.

TLS: certificate is used When this option is chosen, the Advanced CA check box appears and is used the same way as that of the LDAPS type.

User and Password

Fill in the User and Password as required by the directory

Note that the login must match the LDAP syntax requirement to be valid. e.g.: "cn=Directory Manager".

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Multi valued field separator

Type in the value separator in multi-value fields.

Alias dereferencing

Select the option on the list. Never improves search performance if you are sure that no aliases is to be dereferenced. By default, Always is to be used:

Always: Always dereference aliases

Never: Never dereferences aliases.

Searching:Dereferences aliases only after name resolution.

Finding: Dereferences aliases only during name resolution

Referral handling

Select the option on the list:

Ignore: does not handle request redirections

Follow:does handle request redirections

Insert mode

Select the editing mode on the list:

Add: add a value in a multi-value attribute,

Insert or update: Insert a new record. If the record with the given reference already exists, an update would be made.

DN Column Name

Select in the list the type of the LDAP input entity used.

Schema and Edit schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

Built-In: You create and store the schema locally for this component only.

Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more information, see the related description of retrieving table schemas in Talend Studio User Guide.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this option to view the schema only.

• Change to built-in property: choose this option to change the schema to Built-in for local changes.

• Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

Die on error

This check box is selected by default. Clear the check box to skip the row on error and complete the process for error-free rows. If needed, you can retrieve the rows on error via a Row > Reject link.

Use Attribute Options (for update mode)

Select this check box to choose the desired attribute (including dn, dc, ou, objectClass, mail and uid) and the corresponding operation (including Add, Replace, Remove Attribute and Remove Value).

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a job level as well as at each component level.

Global Variables 

NB_LINE: the number of rows processed. This is an After variable and it returns an integer.

NB_LINE_REJECTED: the number of rows rejected. This is an After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage rule

This component covers all possible LDAP queries.

Note: Press Ctrl + Space bar to access the global variable list, including the GetResultName variable to retrieve the relevant DN Base automatically. This component allows you to carry out actions on a table or on the data of a table in an database. It also allows you to create a reject flow using a Row > Rejects link to filter data in error. For an example of tMysqlOutput in use, see Retrieving data in error with a Reject link.
