def get_username(password)
    xpath = "USER[PASSWORD=\"#{password}\"]/NAME"
    username = retrieve_from_userpool(xpath)

    # No exact match, trying to match password with each
    # of the pipe-separated DNs stored in USER/PASSWORD
    if username.nil?
        @lock.synchronize {
            @user_pool.each { |user|
                return user["NAME"] if user["AUTH_DRIVER"] == "x509" && user["PASSWORD"].split('|').include?(password)
