Username shows Undefined Undefined after login to CloudPak dashboard using SAML login option

Symptoms

When you use SAML login as option to login to the Cloudpak console, you might notice that the username is showing Undefined Undefined in the CloudPak dashboard page. You can observe this issue if you are using the foundational services version 3.20 and 3.21.

Causes

Migration from the IdP V2 to V3.

Resolving the problem

As per the SAML V3 schema, given_name and family_name are mapped to the givenname and familyname of IdP. You can update the V3 registration call to resolve this issue.

Steps

Get the V3 registration data

Note:

• The SAML UID that is supported is defaultSP. For more information, see Getting SAML registration by UID.
• Replace base64-encoded-idp-xml with actual base64 encoded idp-metadata that you have received in the GET call.
• Get the cp-console-url by using the command, oc get routes.

To get the existing SAML registration:

API version

1.0.0

API URI components

Scheme

HTTPS

Host IP

Cluster Master Host

Port number

Cluster Master API Port

Path

idprovider/v3/auth/idsource/defaultSP

Command

GET

Command output format

application/json

curl -k -X GET 'https://cp-console.apps.mycluster.mydomain.com/idprovider/v3/auth/idsource/defaultSP' --header "Authorization: Bearer $ACCESS_TOKEN"

Update the V3 registration data by adding first_name and last_name under token_attribute_mappings

1. Copy the response that you get by using the curl command in Get the V3 registration data.

2. Remove the uid entry from the response, "uid":"defaultSP".

3. Add the following attributes, first_name and last_name under the token_attribute_mappings.

    "token_attribute_mappings": {
        "sub": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name",
        "given_name": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname",
        "family_name": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname",
        "groups": "http://schemas.microsoft.com/ws/2008/06/identity/claims/groups",
        "email": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress",
        "first_name": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname",
        "last_name": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname"
    }
   

4. Update the IdP V3 registration by adding the token_attribute_mappings payload as described in Step 3.

Note:

• Replace base64-encoded-idp-xml with actual base64 encoded idp-metadata that you have received in the GET call.

• Get the cp-console-url by using the command, oc get routes.
