Configuring Active Directory User Stores for Inbound Provisioning

WSO2 Identity Server can act both as a SCIM Provider and as a SCIM consumer at the same time. You can test the WSO2 Identity Server's SCIM Provider API as described here. The WSO2 Identity Server build includes the ApacheDS embedded LDAP server. The LDAP server's schema is customized to have the mandatory SCIM attributes, therefore SCIM implementation works by default with the WSO2 Identity Server.

However, when the WSO2 Identity Server is connected to an external LDAP or an Active Directory instance, they might not have these mandatory SCIM attributes in their schema. So the option is to map the SCIM claims to the existing attributes of the Active Directory.

Add a user with the username "john" and password "Wso2@123". Here we have to map the userName (urn:scim:schemas:core:1.0:userName ) SCIM attribute to an existing claim in the Active Directory (e.g.:cn ). Furthermore, when a user is being added in SCIM, there are four more SCIM attributes being added behind the scene. These are the SCIM attributes such as location (urn:scim:schemas:core:1.0:meta.location ), created ( urn:scim:schemas:core:1.0:meta.created), lastModified ( (urn:scim:schemas:core:1.0:meta.lastModified ) and finally the id ( urn:scim:schemas:core:1.0:id ). So we need to map these to existing Active Directory user attributes.

When mapping claims to attributes, there are few things to be considered. The SCIM claim dialect (urn:scim:schemas:core:1.0:id ) uses String type to hold their values. So, when mapping any SCIM claim to an attribute in the Active Directory, make sure to use the attributes which are having the String type. You can find all Active Directory attributes here. Given below is a plausible example for claim mapping,

CLAIM URI MAPPED ATTRIBUTE
urn:scim:schemas:core:1.0:userName cn
urn:scim:schemas:core:1.0:meta.location streetAddress
urn:scim:schemas:core:1.0:meta.created homePhone
urn:scim:schemas:core:1.0:meta.lastModified pager
urn:scim:schemas:core:1.0:id homePostalAddress

This claim mapping can be done through the WSO2 Identity Server Claim Management Feature.

  1. Log in to WSO2 Identity Server using your credentials.
  2. Go to the Main menu in the Management Console menu and click List under Claims.
  3. Select urn:scim:schemas:core:1.0 from the list.
  4. Choose the Id claim and click on Edit.
    id-claim
  5. Change the Mapped Attribute value to homePostalAddress and click Update.
    update-mapped-attribute
  6. Edit the other four claims in the same way.
  7. Now the basic claim mapping is done. You can now add a user using the following curl command.

    • Primary Userstore Command
    curl -v -k --user admin:admin --data "{"schemas":[],"userName":"john","password":"Wso2@123"}" --header "Content-Type:application/json" https://localhost:9443/wso2/scim/Users
    • Secondary Userstore Command
    curl -v -k --user admin:admin --data "{"schemas":[],"userName":'wso2.com/uresh67',"password":"Wso2@123"}" --header "Content-Type:application/json" https://localhost:9443/wso2/scim/Users

    Note that the user name is preceded by the domain and is within single quotes 'wso2.com/uresh67'. Also note that 'wso2.com' here is a reference to a domain name.

    In RestClient, the following header parameters must be added and the double quotations must be removed from the message body.

    Info

    Content-Type: application/json
    Accept: */*
    Message body
    {schemas:[],userName:'wso2.com/uresh67',password:Wso2@123}

    Info

    You need to do the claim mapping for every SCIM claim you are using with user operations.
