Configuring permissions for SCIM 2.0 operations
About this task
This example shows how to correctly configure permissions so POST requests with the "userAdd" scope will succeed. This example assumes that you have set up an LDAP mapping SCIM 2.0 Resource Type for the inetOrgPerson
objectclass (see Configuring an LDAP Mapping SCIM 2.0 resource type.
Steps
-
If the SCIM Resource Type being targeted already has a value for the
create-dn-pattern
property, skip to step 2. Otherwise, the followingdsconfig
command can be used:dsconfig set-scim-resource-type-prop \ --type-name Users \ --set create-dn-pattern:entryUUID=generated,ou=People,dc=example,dc=com
-
Send the following request to the SCIM /Users endpoint:
curl -k -X POST \ https://localhost:8443/scim/v2/Users/ \ -H 'Authorization: Bearer {"active":true}' \ -H 'Content-type: application/json' \ --data '{"username":"user.test", "name":{"formatted":"Test", "familyName":"User"}, "schemas":["urn:pingidentity:schemas:User:1.0"]}'
The response from the server should have a status of 403 and contain a correlation ID, similar to the following:
{ "schemas":["urn:ietf:params:scim:api:messages:2.0:Error"], "status":"403", "detail":"Request failed: correlationID='faa707b3-5d48-42e6-9e78-2c8dbb1e2cac'" }
This is the expected response since this SCIM request does not have the permission needed to write to an entry. See Troubleshoot the SCIM 2.0 servlet extension for instructions on viewing the full server error message.
-
An ACI should now be added to the
ou=People,dc=example,dc=com
subtree. This will grant permission to add entries to the said subtree as long as the SCIM request includes the ‘userAdd’ scope. This can be done by running the followingldapmodify
command. Note that this ACI does not grant write access to attributes, which means modify operations will fail. You can find more information about configuring ACIs in Overview of access control.$ ldapmodify dn:ou=People,dc=example,dc=com changetype:modify add:aci aci:(version 3.0; acl "ACI for userAdd scope"; allow (add) oauthscope="userAdd";)
-
Send the POST request to the SCIM / Users endpoint again, this time including the
userAdd
scope in the bearer token:curl -k -X POST \ https://localhost:8443/scim/v2/Users \ -H 'Authorization: Bearer {"active":true, "scope":"userAdd"}' \ -H 'Content-type: application/json' \ --data '{"username":"user.test", "name":{"formatted":"Test", "familyName":"User"}, "schemas":["urn:pingidentity:schemas:User:1.0"]}'
The response from the server should now contain the created SCIM resource, which should also contain values for the name and username attributes, similar to the following:
{ "name":{ "familyName":"User", "formatted":"Test" }, "username":"user.test", "id":"6f9a89b8-e766-478c-9667-def049daf6bc", "meta":{ "resourceType":"Users", "location":"https://localhost:8443/scim/v2/Users/6f9a89b8-e766-478c-9667-def 049daf6bc" }, "schemas":["urn:pingidentity:schemas:User:1.0"] }
