Custom Attributes

Overview#

Making changes in the schema to add custom columns/attributes

Download the custom_schema.json file:

wget https://raw.githubusercontent.com/JanssenProject/jans/main/jans-linux-setup/jans_setup/schema/custom_schema.json
Make your edits in custom_schema.json:

For example we will add 4 attributes and define them as int, json, bool, and text

Firstly, add the attribute names to the object class:
```
"objectClasses": [
    {
    "kind": "AUXILIARY",
    "may": [
        "intAttribute",
        "jsonAttribute",
        "boolAttribute",
        "textAttribute"
```

Describe the attributes inside attributeTypes. You can refer to RFC 4517:

"attributeTypes": [
    {
    "desc": "int desc",
    "equality": "integerMatch",
    "names": [
        "intAttribute"
    ],
    "oid": "jansAttr",
    "syntax": "1.3.6.1.4.1.1466.115.121.1.27",
    "x_origin": "Jans created attribute"
    },

{
    "desc": "json desc",
    "equality": "caseIgnoreSubstringsMatch",
    "names": [
        "jsonAttribute"
    ],
    "multivalued": true,
    "oid": "jansAttr",
    "syntax": "1.3.6.1.4.1.1466.115.121.1.15",
    "x_origin": "Jans created attribute"
    },

{
    "desc": "bool desc",
    "equality": "booleanMatch",
    "names": [
        "boolAttribute"
    ],
    "oid": "jansAttr",
    "syntax": "1.3.6.1.4.1.1466.115.121.1.7",
    "x_origin": "Jans created attribute"
    },

    {
        "desc": "text desc",
        "equality": "caseIgnoreMatch",
        "names": [
        "textAttribute"
        ],
        "oid": "jansAttr",
        "syntax": "1.3.6.1.4.1.1466.115.121.1.15",
        "x_origin": "Jans created attribute"
    }

],

Create a configmap with the schema file:

kubectl create cm custom-schema-cm --from-file=custom_schema.json -n <namespace>

Mount the configmap in your override.yaml under persistence.volumes and persistence.volumeMounts:

persistence:
    volumeMounts:
        - name: schema
          mountPath: /app/schema/custom_schema.json
          subPath: custom_schema.json
    volumes:
        - name: schema
          configMap:
            name: custom-schema-cm

Run helm install or helm upgrade if Jans has been already installed.

helm upgrade <helm-release-name> janssen/janssen -n <namespace> -f override.yaml --version=1.0.x
