Mapping fields manually

To populate the Profiles database with data from the enterprise LDAP directory, map the content of the fields in the database to the fields in the LDAP directory.

About this task

Edit the map_dbrepos_from_source.properties file to map fields between the Profiles database and the LDAP directory. Open the profiles_functions.js file to see the options for the different mapping functions. You can add your own functions if necessary.

Note: When you run the Profiles population wizard in interactive mode, it generates two property files in the Wizards\TDIPopulation directory: a tdisetting.properties file and a mappings.properties file. The properties in mappings.properties are very similar to those in map_dbrepos_from_source.properties.

To map fields, complete the following steps:

Procedure

On the system hosting your IBM® Tivoli® Directory Integrator installation, create a subdirectory in which to store the Tivoli® Directory Integrator solution directory. Make sure that the file path does not contain spaces. Do not, for example, create the subdirectory in the Program Files directory in Microsoft® Windows®.
Copy the tdisol compressed file from the TDISOL directory of the IBM® Connections installation media to the system where you installed Tivoli® Directory Integrator.
Using appropriate tools, extract the tdisol file to the directory that you created in Step 1. This process creates a Tivoli® Directory Integrator Solution directory called TDI.
Move the OS directory that you copied earlier to jvm/jre/lib/ext subdirectory of the Tivoli® Directory Integrator directory. Rename the directory to TDI. This directory becomes the Tivoli® Directory Integrator solution directory.
From the TDI solution directory, open the tdienv.bat or tdienv.sh file in a text editor. Ensure that the path to the Tivoli® Directory Integrator installation directory is specified correctly in the TDIPATH variable. If the path is not correct, edit the TDIPATH environment variable.
- AIX® or Linux®:
  The default value for TDIPATH is:
```
export TDIPATH=/opt/IBM/TDI/V7.1.1
```
- Windows®:
  The default value for TDIPATH is:
```
SET TDIPATH=C:\Program Files\IBM\TDI\V7.1.1
```
Other scripts in the solution directory use this Tivoli® Directory Integrator path or tdienv.bat or tdienv.sh file to find Tivoli® Directory Integrator files.
Edit the properties files to define the mapping between the LDAP directory and the Profiles database. Consider using LDAP viewer software to help you map the fields. To define the mappings that are used when populating the Profiles database from the enterprise directory:
1. From the TDI directory, open the map_dbrepos_from_source.properties file in a text editor.
2. Add or modify the field values. Any values that you omit or set to null are not populated in the database. You can modify the values in one of the following ways:
  
  1:1 mapping
  
  If one field in the Profiles database matches one field in the enterprise directory, type the name of the field in the Profiles database and set it equal to the associated source database LDAP property. For example:
  bldgId=buildingname
  
  Complex mapping
  
  If there is a more complex relationship between the fields in the Profiles database and enterprise directory, such as the content of the property in the enterprise LDAP directory must be split into multiple fields in the Profiles database, use a JavaScript™ function to define the relationship. Define the function in the profiles_functions.js file and wrap the name of the JavaScript™ function in braces {}. Begin function names with func_ so that you can more easily identify them. For example:
  bldgId={func_map_to_db_bldgId}
  
  Note: See Sample complex mappings of Profiles data for an example of complex mapping.
  Notes:
  - The uid, guid, dn, surname, and displayName attributes are always required.
  - See Table 2 for a list of the default values for the fields.
Open the tdi-profile-config.xml file.
After the Tivoli® Directory Integrator Solution files are extracted, the file is located in the following directory:
TDI/conf/LotusConnections-config

Modify the file to configure the extension attribute, specifying the property's name and mapping from the source. Use the following parameters:

Table 1. Custom extension attribute parameters
Parameter	Description
extensionId	The ID of the extension attribute. This parameter is required.
sourceKey	The name of the attribute from the source, which most often is LDAP. This parameter is required.
length	The maximum number of characters for the field. This parameter is required.

For example, to add a simple attribute called spokenLangs, which is derived from the spokenLang source attribute, the configuration would look like the following extract from the tdi-profile-config.xml file:

<profileExtensionAttributes>
  <simpleAttribute extensionId="spokenLangs" sourceKey="spokenLang" length="80"/>
</profileExtensionAttributes>

Note: The formatting between the tdi-profiles-config.xml and the profiles-config.xml files is compatible, so you can copy and paste configuration information between the files. For the extension to be displayed in the user interface, the modifications must be made in profiles-config.xml. For more information, see Extension properties in the data modelExtension properties in the data model in the Customizing Profiles section.

Note: To leverage the custom attribute in the Profiles user interface or REST API, you must configure the application per the instructions in the Customizing Profiles section. For a detailed example that uses custom attributes, see Creating a simple profile data model and template customization.

Save your changes to the tdi-profiles-config.xml file.
Add the property to the types hierarchy, which is contained in the file profiles-types.xml.
You must add the property to both instances of profiles-types.xml. One instance is in the TDI solution conf/LotusConnections-config directory, and the other instance is in the primary LotusConnections-config directory. The property must be the same in both places. Using the spokenLangs example from previous steps, the property might look like the following example:
```
<property>
   <ref>spokenLangs</ref>
   <updatability>readwrite</updatability>
   <hidden>false</hidden>
</property>
```
If the value of the extension attribute does not appear directly in LDAP, but instead is a function of one or more LDAP attributes, you must write a JavaScript™ function. The function must combine different attributes from your LDAP directory to map a customized extension attribute for the Profiles database.
1. Modify tdi-profiles-config.xml to make the sourceKey the same value as the extensionId.
  For example:
```
<profileExtensionAttributes>
    <simpleAttribute extensionId="spokenLangs" sourceKey="spokenLangs" length="80"/>
</profileExtensionAttributes>
```
2. Add the extension attribute function definition in the map_dbrepos_from_source.properties file, using the following format:
```
extattr.spokenLangs={func_map_to_langs}
```
  Note: In this example, the extension attribute is spokenLangs. The extension attribute must match the specified extensionId in the tdi-profiles-config.xml extension attribute definition.
3. Add a new func_map_to_langs JavaScript™ function in the TDISolution\TDI\profiles_functions.js file. Write logic for the function that specifies the new extension attribute mapping.
  In the following example, work.getString("c") retrieves the country code from the LDIF obtained from LDAP. All LDAP attributes are available. By default, the LDAP country code attribute is named "c", but it might be different in your environment.
```
function func_map_to_langs(fieldName) {
  var country = work.getString("c");
  var retval = "Unknown";

  if ( country == "us" )
    retval = "English";
  elseif ( country == "fr" ) 
    retval = "French";

  return retval;
}
```
4. Repeat these steps for each JavaScript function.

What to do next

The properties in the map_dbrepos_from_source.properties file have the default values defined in the following table. Many of them are null. You must determine which LDAP properties to map to your database fields and edit this file to specify values that apply to your configuration. Any values that you omit or set to null are not populated in the database.

Note: See Attribute mapping for Profiles for a table of additional attribute mapping field values.

Mapping the guid, uid, and loginId: The guid property identifies the global unique ID of a user. This property's value is created by the LDAP directory and is unique, complex, and never changes. It is essential in that it maps each user's IBM® Connections data to their User ID when using the Profiles database as the user repository. The mapping of the guid property must be handled differently depending on the type of LDAP directory that you are using:

Microsoft® Active Directory
guid={function_map_from_objectGUID}
You must use a JavaScript™ function to define the value for Active Directory because objectGUID is stored in Active Directory as a binary value, but is mapped to guid, which is stored as a string in the Profiles database. Also, the samAccountName property used by Active Directory has a 20 character limit, as opposed to the 256 character limit of the other IDs used by IBM® Connections.
IBM® Lotus® Domino®
guid={function_map_from_dominoUNID}
IBM® Directory Server
guid=ibm-entryUuid
Sun Java™ System Directory Server
guid=nsUniqueID
Novell Directory
guid={function_map_from_GUID}

If you edited the wimconfig.xml or LotusConnections-config.xml file to use a custom global unique ID, be sure to specify that custom ID here. If you specify an attribute here other than the default, you must edit the federated directory configuration to match the guid used here. See also Specifying the global ID attribute for users and groups and Specifying a custom ID attribute for users or groups. If the custom ID is different for users and groups, see Configuring the custom ID attribute for users or groups.

The uid property, not to be confused with the guid property, defines the unique ID of a user. This property differs from a guid in that it is the organization-specific permanent identifier for a user – often a login ID or some value based on the user's employee code. The uid is a critical field in the Profiles database. By default, this property links a given person's user record back to LDAP data. The value you map to uid must meet the following requirements:

It must be present in every entry that is to be added to the database.
It must be unique.
In a multi-LDAP environment, it must be unique across LDAP directories.
It must be 256 characters or fewer in length.

In Active Directory, although there often is a UID field available, this field is not always the best choice for mapping to uid because it is not guaranteed to be present for all entries. A better choice is sAMAccountName because it usually does exist for all entries. Other values are acceptable also, as long as they meet the requirements.

Notes:

If you are mapping the uid from an LDAP field, specify the name of the field. However, if you need to parse it from the distinguished name and it is in the DN in the form of uid=value, use the following mapping function:
{func_map_to_db_UID}
Use the isManager and managerUid properties to set up the organizational structure of the organization. The isManager field determines whether the current person is a manager or not. You must assign a Y (Yes) or N (No) value to this property for each entry. Y identifies the person as a manager. The managerUid identifies the UID of the current person's manager. By default, managerUid is mapped to $manager_uid, which represents a lookup of the UID of the manager (using the Distinguished Name contained in the LDAP manager field). If a user's manager information is not contained in the $manager_uid field, you should adjust the mapping accordingly. These two properties work together to identify manager/employee relationships and create a report-to chain out of individual user entries.
If users intend to log into Profiles using a single-valued user name other than the value specified in the uid or email properties, you must map that user name value to the loginId property. To do so, complete the following step:
- Set the loginId property in the map_dbrepos_from_source.propeties file equal to the LDAP property that you want to use as the login ID. For example, if you want to use employeeNumber as the login property, edit the property value as follows:
  loginId=employeeNumber
If you have more than one additional login ID (such as with a long and short form user ID) and you want to allow users to login with either of their login IDs, you can populate multiple additional login IDs by using one of the following settings:
logins=multiValuedLdapAttribute
or
logins={function_to_get_multiple_ldap_values}

For more information, see the IBM® Tivoli® Directory Integrator documentation.

Adding profile types:

IBM Connections supports the ability to classify a profile using a profile type. The profile type allows the application to provide the set of properties that are intended for a given profile object. For more information, see Profile-types.
