    JSCAS Clearpass

    This is a plugin for the JSCAS server. It is used to intercept a user's credentials as they are logging in and store them in a cache. The cache is either a Redis or MongoDB database. Therefore, the server must have either storage mechanism configured. If both are configured then the Redis database will take precedence.

    This plugin exposes a REST API for retrieving the stored credentials.

    Caution: if you can avoid using this plugin, then you should do so. Caching a user's credentials, despite them being encrypted before storing, is a bad idea.

    But, if you have no choice, then it is highly recommended that you access the API via a server-side method, and that you allow only specific servers to access the API (i.e. apply a very strict incoming firewall).

    Database Notes

    • Redis: honors the configured lifetime. If set to 0, it is left up to the administrator to clean up the database.
    • MongoDB: does remove entries after the configured lifetime. It is left up to the administrator to clean up the database. Consider using mongo-purge to handle this.


    The configuration should be added to the server's configuration under the plugins configuration section. It should be under the key clearpass.

      encryptionKey: 'at least a 32 character string',
      lifetime: 0,
      authKeys: ['string key'],
      mongodbName: 'string'

    The lifetime property specifies how long, in milliseconds, a set of stored credentials should be valid. A setting of 0 indicates that the sealed credentials are indefinitely valid. You should set this to a reasonably short time.

    The authKeys property specifies a set of bearer tokens for clients that are allowed to query the REST API. There must be at least one key present.

    The mongodbName property is only required if using the MongoDB backend. This option is required when using MongoDB because since v3.0.0 of the mongodb driver, it's prohibitively difficult to determine the correct database via the connection. See their issue NODE-1258.


    All requests to the API must include the Authorization header. This header must contain a valid API key prefixed with bearer. Keys can be any string that are valid for an HTTP header value (rfc2616 §4.2).

    Example: Authorization: bearer 123456.

    /clearpass/{username}/credentials GET

    Retrieves the given username's credentials. If the credentials are stored, and nothing is wrong with the request, you will get back a JSON representation of the object:

      username: String,
      password: String

    If errors have occurred, you will receive an appropriate HTTP status.
