Extend the Active Directory Schema by Adding Custom Attributes
This section applies to CA Identity Manager and CA Secure Cloud. The information here is not relevant to CA Identity Governance.
This section applies only to CA Identity Manager.
The Active Directory connector lets you manage additional attributes, including an extended Active Directory schema.
The mapping extended Active Directory attributes mechanism has limited functionality and is not intended to support the full functionality of built-in Active Directory attributes. The mechanism assumes that all of the following conditions are true:
- Extended attributes that are defined in the attribute map must be set for all managed accounts.
- The values of the extended attributes that are defined in the attribute map must have a fixed length.
- The connector applies your extensions to the entire enterprise.
The Active Directory connector cannot manage some sensitive attributes that are protected by Active Directory.
Follow these steps:
- Create theschema.extfile at the following location:<ProvisioningServer_HOME>\data\ADSIf C++ Connector Server (CCS) is located on a separate machine, ensure that you create theschema.extfile on CCS too at the following location:<ConnectorServer_HOME>\ccs\data\adsAfter creating theschema.extfile, restart CCS.
- In the text file, list the display name of each attribute on a single line by itself. Include the following attributes:
- Any custom ADS account attributes that have been added to the ADS schema
- Any ADS account attributes that do not actually exist in the ADS schema but are used in ADSExitUsrPreAdd.txt and ADSExitUsrPostAdd.txt.
- Restart the Provisioning Server.The Provisioning Manager now displays a new property page named Custom, for both account templates and accounts. This new page lists the extended attributes and their values.You can now map the extended Active Directory attributes to a global user's attributes and custom fields by using rule strings in Active Directory account templates.
Note:If you delete attributes from the schema.ext file, the following steps happen in the Provisioning Manager:
- Attributes are removed from the list of extended attributes on the Custom tab on the ADS Account property sheet.
- Attributes are marked as invalid (N) in the Valid column on the ADS Account Template property sheet. You can then remove the attributes and delete them from the provisioning repository.
Example: Correlate Active Directory Extended Attributes
Extended Active Directory schema attributes that are set for a particular account are stored together with their values in the account's attribute called 'eTADSpayload' (user-friendly name 'payload') in the following format:
<reservedValue> is a value reserved for future use. It is currently always set to 01.
Attribute mapping can be set from the managed Active Directory endpoint by specifying a mapping function substring with an offset and length. For more detailed information, see the section "Explore and Correlate Parameters" in the
Provisioning Reference Guide.

The following is an example of mapping the extended attributes to a global user's custom attributes:
eTADSpayload extendedAttribute1:01:0006=value1;extendedAttribute2:01:0007=value10;extendedAttribute2:01:0008=value100 eTCustomField01=eTADSpayload:SUB(28,6) eTCustomField02=eTADSpayload:SUB(62,7) eTCustomField03=eTADSpayload:SUB(97,8)
The attribute mapping mechanism uses substring (SUB) and it specifies the offset and the length of the value.
