Using Command Line#

In the Janssen Server, you can deploy and customize the Config-API Configuration using the command line. To get the details of Janssen command line operations relevant to Config-API Configuration, you can check the operations under ConfigurationConfigApi task using the command below:

Command
/opt/jans/jans-cli/config-cli.py --info ConfigurationConfigApi

It will show the details of the available operation-ids for Config-API.

Sample Output
/opt/jans/jans-cli/config-cli.py --info ConfigurationConfigApi
Operation ID: get-config-api-properties
 Description: Gets config-api configuration properties.
Operation ID: patch-config-api-properties
 Description: Partially modifies config-api Configuration properties.
 Schema: Array of JsonPatch

To get sample schema type /opt/jans/jans-cli/config-cli.py --schema-sample <schema>, for example /opt/jans/jans-cli/config-cli.py --schema-sample JsonPatch

Get The Current Config-API Configuration#

Configuration for Config-API is a set of key-value pairs, called properties. When we retrieve the configuration, these properties and their current values are returned as a JSON document. To get the properties of Janssen Config-API Configuration, run the command below:

Command
/opt/jans/jans-cli/config-cli.py --operation-id=get-config-api-properties

It will return the result as below:

Update Config-API Configuration Properties#

To update the configuration, we will use JSON patch schema as shown below.

Let's say we want to stop the file extension validation done by config-api's asset management module. This can be done by setting the fileExtensionValidationEnabled property to false. To do that, write a text file (config-api-assetmgt-patch.json) with the content that follows the JSON patch schema.

config-api-assetmgt-patch.json

5

7
[
 {
    "op": "replace",
    "path": "/assetMgtConfiguration/fileExtensionValidationEnabled",
    "value": false
 }
]

Now, execute the following command to apply this patch:

Command
 /opt/jans/jans-cli/config-cli.py \
--operation-id=patch-config-api-properties --data ./config-api-assetmgt-patch.json
Upon successful execution of the update, the Janssen Server responds with updated configuration.

Updating multi-valued property#

Let's say we want to update the configuration property userMandatoryAttributes. This property's value is a list of attributes. We want to remove an attribute from the list. For this, we will have to create a JSON patch file that contains the new list and then run a command to push the update to the Janssen Server. Let's do this step-by-step:

  1. Get the current value list for userMandatoryAttributes property using steps mentioned in Get the current configuration section
  2. Using the current list of values as a starting point, create a JSON patch file config-api-patch.json as below. Update the list as desired by adding or removing items from the list:

     "givenName",

]
}

Now, execute the following command to apply this patch:

Command
 /opt/jans/jans-cli/config-cli.py \
--operation-id=patch-config-api-properties --data ./config-api-patch.json

Two options to make effect any manual changes done to the configuration#

  1. Restart jans-config-api
  2. Increment the jansRevision property of the configuration without restarting the application. The timer job will detect the change and fetch the latest configuration from the DB.

Locating Config API configuration in the Persistence Layer#

While it is not recommended that an administrator directly edits a configuration at the persistence layer, it may be useful information for a developer.

A. MySQL#

erDiagram
 jansAppConf {
 string doc_id PK ""
 string ou  "jans-config-api"
 string jansConfDyn "json configuration for the app"
 }

B. LDAP#

graph LR
A[ou=jans] --> V(ou=configuration)
 V --> V5[ou=jans-config-api]

Important attributes#

OAuth authorization#

configOauthEnabled property can be used to enable or disable the oAuth2 authorization. By default, it is set to true.

 "configOauthEnabled": true

Api protection#

apiProtectionType property states the protocol used for API authorization. The currently supported value is oauth2.

 "apiProtectionType": "oauth2"

Api protection auth server#

apiApprovedIssuer property enables to set more than one authorization servers. By default, the current auth-server is set. You can add more servers separated by commas.

 apiApprovedIssuer": ["https://<jans.auth.server>,https://<gluu.server>,https://<anyAuth.server>"]

Logging level#

loggingLevel property can be used to change the logging level to the desired values (TRACE, DEBUG, INFO, WARN, ERROR). By default, the level is set to INFO

```javascript

"loggingLevel":"DEBUG",

```

Scopes other than the one defined by config-api#

Config API endpoints are oAuth2 protected. These scopes are created during installation. However, few endpoints require scopes defined by other modules like auth-server.

A list of these scopes is maintained in the configuration in order to avoid the creation of these scopes during Config API start-up. exclusiveAuthScopes property can be used to change the logging level to the desired value (TRACE, DEBUG, INFO, WARN, ERROR). By default, the level is set to INFO

 "exclusiveAuthScopes": [
   "jans_stat",
   "https://jans.io/scim/users.read",
   "https://jans.io/scim/users.write"
],

User - Mandatory and exclusion attributes#

MandatoryAttributes#

userMandatoryAttributes can be used to define mandatory attributes for User while creating and updating.

  "userMandatoryAttributes": [
 "mail",
 "displayName",
 "jansStatus",
 "userPassword",
 "givenName"
],

Exclusion attributes#

userExclusionAttributes can be used to define User attributes that are not to be returned in the API response. More attributes that are to be skipped in response can be added to the list.

  "userExclusionAttributes": [
    "userPassword"
 ],

Agama flow configuration#

agamaConfiguration stores Agama-related configuration used in Agama related endpoints.

mandatoryAttributes list defines the required attributes for Agama flow creation and update. optionalAttributes list specifies the optional attributes.

  "agamaConfiguration": {
     "mandatoryAttributes": [
   "qname",
   "source"
 ],
   "optionalAttributes": [
   "serialVersionUID",
   "enabled"
 ]
 }

Using Text-based UI#

In the Janssen Server, You can manage Config-API Configuration using the Text-Based UI also.

You can start TUI using the command below:

Command
sudo /opt/jans/jans-cli/jans_cli_tui.py

Navigate to Config API section where administrators can update Config-API configurations in six sub-tabs, namely Main, Agama, Plugins, Asset Management, Audit Log Conf, Data Format Conversion

Using Configuration REST API#

Janssen Server Configuration REST API exposes relevant endpoints for managing and configuring the Config-API Configuration. Endpoint details are published in the Swagger document, see endpoint /api/v1/api-config
