Configuring the FIDO2 server:

1. Read Configuration parameters:

Use the following command to obtain configuration parameters:

jans cli --operation-id get-properties-fido2

Response:

{
  "issuer": "https://my.jans.server",
  "baseEndpoint": "https://my.jans.server/jans-fido2/restv1",
  "cleanServiceInterval": 60,
  "cleanServiceBatchChunkSize": 10000,
  "useLocalCache": true,
  "disableJdkLogger": true,
  "loggingLevel": "DEBUG",
  "loggingLayout": "text",
  "metricReporterInterval": 300,
  "metricReporterKeepDataDays": 15,
  "metricReporterEnabled": true,
  "personCustomObjectClassList": [
    "jansCustomPerson",
    "jansPerson"
  ],
  "superGluuEnabled": true,
  "sessionIdPersistInCache": false,
  "oldU2fMigrationEnabled": true,
  "fido2Configuration": {
    "authenticatorCertsFolder": "/etc/jans/conf/fido2/authenticator_cert",
    "mdsCertsFolder": "/etc/jans/conf/fido2/mds/cert",
    "mdsTocsFolder": "/etc/jans/conf/fido2/mds/toc",
    "checkU2fAttestations": false,
    "userAutoEnrollment": false,
    "unfinishedRequestExpiration": 180,
    "authenticationHistoryExpiration": 1296000,
    "serverMetadataFolder": "/etc/jans/conf/fido2/server_metadata",
    "metadataUrlsProvider": "",
    "skipDownloadMdsEnabled": false,
    "skipValidateMdsInAttestationEnabled": false,
    "assertionOptionsGenerateEndpointEnabled":true,
    "requestedCredentialTypes": [
      "RS256",
      "ES256"
    ],
    "requestedParties": [
      {
        "name": "https://my.jans.server",
        "domains": [
          "my.jans.server"
        ]
      }
    ]
  }
}

2. Update configuration parameters:

Steps: A. Create a JSON file say /tmp/config_values.json by editing the JSON from Point 1 B. Use the following command jans cli --operation-id post-config-scripts --data /tmp/config_values.json

3. Change log level of FIDO2 server

Steps: A. Create a JSON file say /tmp/config_values.json by editing the JSON from Point 1. Edit loggingLevel to TRACE or DEBUG or INFO B. Use the following command jans cli --operation-id put-properties-fido --data /tmp/config_values.json

4. Locating FIDO2 configuration in 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.

MySQL

erDiagram
    jansAppConf {
        string doc_id PK ""
        string ou  "jans-fido2"
        string jansConfDyn "json configuration for the app"
    }
