Confused about diff between Authenticator and authenticate functions.

[CodisRedding]

Can you help me understand why I need to pass creds to both Authenticator's constructor and the authenticate functions?

const authenticator = new Authenticator({
    url: 'ldap://127.0.0.1:1389',
    baseDN: 'dc=domain,dc=com',
    // ******************************
    // HERE
    // ******************************
    username: 'auth@domain.com',
    password: 'password',
    logging: {
        name: 'ActiveDirectory',
        streams: [
            {
                level: 'error',
                stream: process.stdout
            }
        ]
    }
});

// ******************************
// AND HERE
// ******************************
authenticator.authenticate('user@domain.com', 'password')
.then(({auth, user, groups}) => {
    if (auth) {
        const token: string = authenticator.sign({user, groups}, 'no-so-secret-key', {
            expiresIn: '1 day'
        });

        // your script ...
    }
})
.catch((err) => {
    console.log(err);
});
