LDAP Functions

LDAP (Lightweight Directory Access Protocol) is a protocol that allows you to search and update a directory. It is supported by numerous directory servers such as Microsoft Active Directory and Netscape Directory Server. A directory usually contains information about users and network resources, but can contain any kind of data.These functions allow scripts and transformations to connect to a directory using LDAP.

The use pattern follows these steps:

• LDAPConnect(): Establishes a connection to the server
• LDAPAdd(), LDAPReplace(), LDAPRemove(),..: Queues actions to be taken
• LDAPExecute(): Executes the queue on the server

For searching, you can follow this pattern:

• LDAPConnect(): Establishes a connection to the server
• LDAPSearch(): Executes the search on the server and returns the result

Setting LDAP Passwords Programmatically

As of Harmony version 9.9, LDAP passwords can be set using these LDAP functions. The password needs to first be converted to binary before it can be set. (The password may require enclosing in double quotes prior to the conversion to binary, as Active Directory requires values to be enclosed in double quotes.)  This script fragment shows how this could be accomplished:

LDAPConnect("directory.company.example.com:10389", "admin", $adminpassword, 0);
$plain = '"J1tterb1t!@#"';
$pwd = StringToHex($plain);
$i=0;
$newPwd = "";
While($i < Length($pwd)/2,
    $newPwd = $newPwd + Mid($pwd, $i * 2, 2) + "00";
    $i = $i+1;
);
$newPwd = HexToBinary($newPwd);

LDAPReplace("unicodePwd", $newPwd);
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

ArrayToMultipleValues

Declaration

string ArrayToMultipleValues(array arr)

Syntax

ArrayToMultipleValues(<arr>)

Required Parameters

• arr: An array with values to be used to populate a multiple-valued LDAP attribute

Description

Signals that an array should be used to populate a multiple-valued LDAP attribute when mapping to an LDAP target. The array is converted to XML and interpreted when the LDAP server is written to.

Examples

// Create two LDAP attributes using an array
arr = Array();

// Length(arr) will always return the index of
// the next-after-last element of an array
arr[Length(arr)] = "First instance";
arr[Length(arr)] = "Second instance";

// The array will be converted to the string 
// "<JB_Array><it>First instance</it><it>Second instance</it></JB_Array>"
result = ArrayToMultipleValues(arr);

LDAPAdd

Declaration

bool LDAPAdd(string ldapType, string ldapValue)

Syntax

LDAPAdd(<ldapType>, <ldapValue>)

Required Parameters

• ldapType: The LDAP record or attribute type
• ldapValue: The value to be added for the type

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

After a connection is established, the LDAPAdd() function is used to add entries and attributes to the connected LDAP directory. The value is added to the node specified in the LDAPExecute() function, which should be called immediately afterwards to have the changes take effect.

See also the LDAPConnect() and LDAPExecute() functions.

Examples

// Adding a user entry to a directory:
LDAPAdd("objectClass", "user");
LDAPAdd("cn", "wright");
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

// Adding attributes to a user:
LDAPAdd("description", "Thinks a lot.");
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPConnect

Declaration

bool LDAPConnect(string hostname, string user, string password[, int mode, long port])

Syntax

LDAPConnect(<hostname>, <user>, <password>[, <mode>, <port>])

Required Parameters

• hostname: Hostname of an LDAP server to connect to; can include a port, such as directory.example.com:10389

• user: User name to connect to the LDAP host
• password: Password to use to connect to the LDAP host

Optional Parameters

• mode: Connection mode; one of:
  • 0: Non-secure connection; default port: 389
  • 1: Secure connection; default port: 389
  • 2: Secure connection using LDAP over SSL; default port: 636
• port: Port to use to connect to the LDAP host (-1 indicates to use the default LDAP ports)

Description

Connects to a directory using LDAP.

See also the LDAPExecute() function.

Examples

// Connects to an LDAP server using hostname:port, username, password, mode
connected = LDAPConnect("directory.company.example.com:10389", "admin", $adminpassword, 0);

LDAPDeleteEntry

Declaration

bool LDAPDeleteEntry(string distinguishedName)

Syntax

LDAPDeleteEntry(<distinguishedName>)

Required Parameters

• distinguishedName: An LDAP distinguished name to be removed from the currently connected server

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

After a connection is established, the LDAPDeleteEntry() function is used to remove an entry specified by a distinguished name.

See also the LDAPConnect() and LDAPExecute() functions.

Examples

LDAPDeleteEntry("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPExecute

Declaration

bool LDAPExecute(string distinguishedName)

Syntax

LDAPExecute(<distinguishedName>)

Required parameters:

• distinguishedName: An LDAP distinguished name on the currently connected server

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

After a connection is established, the LDAPExecute() function is used to execute one or more modifications (add, remove, replace) that have previously been specified with the LDAPAdd(), LDAPRemove(), or LDAPReplace() functions.

See also the LDAPConnect() and LDAPExecute() functions.

Examples

// Adding LDAP entries and executing them
LDAPAdd("description", "Thinks a lot."); 
LDAPReplace("telephoneNumber", "(510) 555 1000"); 
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPRemove

Declaration

bool LDAPRemove(string ldapType, string ldapValue)

Syntax

LDAPRemove(<ldapType>, <ldapValue>)

Required Parameters

• ldapTyp: The LDAP attribute type
• ldapValue: The value to be removed for the specified attribute type

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

Once a connection is established, the LDAPRemove() function is used to remove an attribute of a specified type and with a specified value.

If the attribute type of that value is not found, an error is thrown. See also the LDAPConnect() and LDAPExecute() functions.

Examples

// Removing an LDAP entry and executing it
LDAPRemove("telephoneNumber", "(510) 555-1000");
LDAPAdd("telephoneNumber", "(510) 555-2000");
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPRename

Declaration

bool LDAPRename(string distinguishedName, string newRDN[, string newParent, bool deleteOldRDN])

Syntax

LDAPRename(<distinguishedName>, <newRDN>[, <newParent>, <deleteOldRDN>])

Required Parameters

• distinguishedName: The path of the directory entry (distinguished name) to be renamed

• newRDN: The new relative distinguished name

Optional Parameters

• newParent: The distinguished name of the new parent of this entry; the default is empty
• deleteOldRDN: If true, the old relative distinguished name will be deleted; the default is false

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

Once a connection is established, the LDAPRename() function is used to change the distinguished name of an entry in the connected directory.

See also the LDAPConnect() and LDAPExecute() functions.

Examples

LDAPRename("telephoneNumber", "telephoneNumberHome");
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPReplace

Declaration

bool LDAPReplace(string ldapType, string ldapValue)

LDAPReplace(<ldapType>, <ldapValue>)

Required Parameters

• ldapType: The LDAP record or attribute type
• ldapValue: The new value to be set for the type

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

Once a connection is established, the LDAPReplace() function is used to replace an existing attribute's value with a new value.

See also the LDAPConnect() and LDAPExecute() functions.

Examples

// Replacing an LDAP entry and executing it
LDAPReplace("telephoneNumber", "(510) 555-1000");
LDAPExecute("CN=wright,CN=Users,DC=company,DC=example,DC=com");

LDAPSearch

Declaration

string LDAPSearch(string path, string filter, int detail, string attribute1[, ... string attributeN])

Syntax

LDAPSearch(<path>, <filter>, <detail>, <attribute1>[, ... <attributeN>])

Required Parameters

• path: The distinguished name used as the base of the search
• filter: A query string search filter, as defined by RFC 4515
• detail: Details to be returned:

1. • 0: Pass to return a simple string that is the first attribute found that matches the filter

   • 1: Pass to return an XML representation of the search results. This can be set to a data element using the Set() function and then accessed later using Get() and an XPath query using the SelectSingleNode() function.

   • 2: Pass to return a 2-dimensional array, where each row represents an LDAP entry and where the row elements are the values of the attributes. Access the elements using the Get() function.

• attribute,... attributeN: An attribute to be included in the search result (in other words, the attribute you are searching for). Additional attributes can be specified; separate them by commas.

Description

To use this function, the LDAPConnect() function must first be used to establish a connection with the LDAP directory.

Once a connection is established, the LDAPSearch() function is used to search within the connected directory.

See also the LDAPConnect() and LDAPExecute() functions.

Controlling Jitterbit Variables

These Jitterbit variables affect the search:

Examples

// Connecting to an LDAP server using a password set 
// in a global variable ("$ldapPassword") and then performing a search
LDAPConnect("directory.company.example.com", "ghvwright", $ldapPassword, 0);
directorySearchResults = LDAPSearch("CN=Users,DC=company,DC=example,DC=com",
  "(&(objectCategory=person)(objectClass=user))", 1, "name", "whenCreated",
  "description", "telephoneNumber");
