MongoDB (v6.2)

pac4j allows you to validate username/password and create, update and delete users on a MongoDB database.

1) Dependency

You need to use the following module: pac4j-mongo.

Example (Maven dependency):

<dependency>
    <groupId>org.pac4j</groupId>
    <artifactId>pac4j-mongo</artifactId>
    <version>${pac4j.version}</version>
</dependency>

2) MongoProfileService

The MongoProfileService allows you to:

• validate a username/password on a MongoDB database (it can be defined as the Authenticator for HTTP clients which deal with UsernamePasswordCredentials)
• create, update or delete a user in the MongoDB database.

It works with a MongoProfile.

It is built from a com.mongodb.MongoClient.

Example:

MongoClient mongoClient = new MongoClient(server, port);
MongoProfileService mongoProfileService = new MongoProfileService(mongoClient);

The users are managed in a users database in a users collection, but both can be changed via the setUsersDatabase(String) and setUsersCollection(String) methods. As well as the id, username and password attribute names using the setIdAttribute, setUsernameAttribute and setPasswordAttribute methods.

The attributes of the user profile can be managed in the MongoDB collection in two ways:

• either each attribute is explicitly saved in a specific attribute and all these attributes are defined as a list of names separated by commas via the setAttributes method (it’s the legacy mode existing since version 1.9)
• or the whole user profile is serialized and saved in the serializedprofile attribute.

This MongoProfileService supports the use of a specific PasswordEncoder to encode the passwords in the MongoDB database.
