Support and Documentation

Some developer-level features are available through the Brightspot UI, such as the HTML toggle on the rich-text toolbar and the Developer submenu in the navigation menu. Users without a role are by default super users, and have access to all Brightspot features including those at the developer level.

To block super users' access to the developer-level features, set the key brightspot/missingRolePermissions. The following table describes the attributes associated with this key.

The following snippet blocks access to all developer-level features—those in the navigation menu and those in widgets.

<Environment name="brightspot/missingRolePermissions" type="java.lang.String" value="+/ -area/developer -area/developer/ -developer/"/>

The key cms/tool/changePasswordTokenExpirationInHours configures the number of hours after which a temporary Brightspot-generated password expires. The following table describes the attributes associated with this key.

The following snippet specifies password token expiration after 48 hours.

<Environment name="cms/tool/changePasswordTokenExpirationInHours" type="java.lang.Long" value="48" />

The key cms/tool/forgotPasswordIntervalInMinutes specifies the number of minutes before Brightspot sends another password-reset email to the same user. This option protects Brightspot from processing automated repeated password-reset requests from the same user within an unreasonably short period of time.

The following table describes the attributes associated with this key.

The following snippet indicates users can submit password reset requests every 15 minutes.

<Environment name="cms/tool/forgotPasswordIntervalInMinutes" type="java.lang.Long" value="15" />

The key dari/userPasswordPolicy/ declares available password policies. A password policy validates new or changed passwords for complexity, such as number of characters, character types in the password (alphanumeric, special characters), and if the password can be reused within a period of time. You can declare multiple password policies, and assign one of them to your Brightspot instance.

The following table describes the attributes associated with this key.

The following snippet declares two policies for validating password complexity.

<Environment name="dari/userPasswordPolicy/simple/class" type="java.lang.String" value="brightspot.core.tool.SimplePasswordPolicy" />
<Environment name="dari/userPasswordPolicy/hardened/class" type="java.lang.String" value="brightspot.core.tool.HardenedPasswordPolicy" />

Both classes SimplePasswordPolicy and HardenedPasswordPolicy must implement UserPasswordPolicy, as in the following example.

package brightspot.core.tool;

import java.util.Map;

import com.psddev.dari.util.PasswordException;
import com.psddev.dari.util.UserPasswordPolicy;

public class SimplePasswordPolicy implements UserPasswordPolicy {

    @Override
    public void initialize(String settingsKey, Map<String, Object> settings) {
       /* Initialization code */
    }

    @Override
    public void validate(Object user, String password) throws PasswordException {
       /* Validation code */
    }
}

The key cms/tool/userPasswordPolicy activates one of the password policies declared with the key dari/userPasswordPolicy/. The following table describes the attributes associated with this key.

The following snippet activates the password policy simple that was declared in the snippet Declaring available password policies.

<Environment name="cms/tool/userPasswordPolicy" type="java.lang.String" value="simple" />

The key <id>/passwordHistoryLimit specifies the previous number of passwords to retain for a user's account. You can use this limit to ensure a user does not use a previous password.

The following table describes the attributes associated with this key.

The following snippet specifies retaining a user's ten previous passwords (including the current one) when the user password policy simple is activated.

<Environment name="simple/passwordHistoryLimit" type="java.lang.String" value="10" />

The key dari/authenticationPolicy/ declares available authentication policies. An authentication policy can check if a user object exists corresponding to the username in the login form, if the user's password expired and needs to be reset, and can validate attempted logins from suspicious domain names. You can declare multiple authentication policies, and assign one of them to your Brightspot instance.

The following table describes the attributes associated with this key.

The following snippet declares two policies for authenticating attempted logins.

<Environment name="dari/authenticationPolicy/simple/class" type="java.lang.String" value="com.psddev.cms.db.SimpleAuthenticationPolicy" />
<Environment name="dari/authenticationPolicy/hardened/class" type="java.lang.String" value="com.psddev.cms.db.HardenedAuthenticationPolicy" />

Both classes SimpleAuthenticationPolicy and HardenedAuthenticationPolicy must implement AuthenticationPolicy, as in the following example.

package com.psddev.cms.db;

import java.util.Map;

import com.psddev.dari.util.AuthenticationException;
import com.psddev.dari.util.AuthenticationPolicy;

public class SimpleAuthenticationPolicy implements AuthenticationPolicy {

    @Override
    public ToolUser authenticate(String username, String password) throws AuthenticationException {
        /* Authentication code that returns a ToolUser object. */
        return user;
    }

    @Override
    public void initialize(String settingsKey, Map<String, Object> settings) {
        /* Initialization code. */
    }
}

The key cms/tool/authenticationPolicy activates one of the password policies declared with the key dari/authenticationPolicy/. The following table describes the attributes associated with this key.

The following snippet activates the authentication policy simple that was declared in the snippet Declaring available authentication policies.

<Environment name="cms/tool/authenticationPolicy" type="java.lang.String" value="simple" />

<Environment name="{custom}/passwordHistoryLimit" type="java.lang.String" value="10" override="false" />

Key: {custom}/passwordHistoryLimit Type: java.lang.String

The number of past passwords to keep for a user. Replace the {custom} placeholder with a value used by a custom password policy that implements com/psddev/dari/util/UserPasswordPolicy. The value is an identifier that is used to look up this configuration setting. If this option is not set, then there is no limit.

The key PRODUCTION toggles between production and development environments. The following table describes the some of the differences between these environments.

The following table describes the attributes associated with this key.

The following snippet configures an instance of Brightspot to run in production mode.

<Environment name="PRODUCTION" type="java.lang.Boolean" value="true" />

Step 1: Create authentication policy implementation

The following code example shows a custom implementation of AuthenticationPolicy. CustomAuthenticationPolicy extends ToolAuthenticationPolicy. This Brightspot base class does the work of validating user passwords. It also checks if the cms/tool/userPasswordPolicy key is set with a custom password policy implementation. If it is, ToolAuthenticationPolicy invokes the implementation to validate the password.

In the event that ToolAuthenticationPolicy cannot validate the user, CustomAuthenticationPolicy checks if the user has reached the login-attempt limit. It does this by accessing the value of the cms/tool/userPasswordPolicy key.

public class CustomAuthenticationPolicy extends ToolAuthenticationPolicy implements AuthenticationPolicy {

    @Override
    public ToolUser authenticate(final String username, String password) throws AuthenticationException {

        ToolUser user = null;
        try {         
            user = super.authenticate(username, password);
        } catch (AuthenticationException e) {
            user = Query.from(ToolUser.class).where("email = ? or username = ?", username, username).first();
            if (user != null) {
                /* Check if the login attempt limit has been reached. */
                long loginAttemptLimit = Settings.getOrDefault(long.class, "acme/loginAttemptLimit", 0L);
                if (loginAttemptLimit > 0
                     && helperClass.getConsecutiveFailedLogins().size() >= loginAttemptLimit) {
                    throw new AuthenticationException("Too many failed login attempts. Please contact your System Administrator.");
                }
            }
            throw e;
        }
        return user;
    }
}

Step 2: Create password policy implementation

A custom password policy implements UserPasswordPolicy. It typically checks that a new password complies with defined string requirements like length and character type. A password policy can also access the passwordHistoryLimit key to limit reuse of a password within a defined history limit.

public class CustomPasswordPolicy implements UserPasswordPolicy {

    @Override
    public void validate(Object user, String password) throws PasswordException {

        /* Validate password */

    }
}

Step 3: Configure custom authentication policy

The Tomcat context.xml file includes the security keys to configure Brightspot for the custom authentication and password policy implementations.

 <Environment name="dari/userPasswordPolicy/acme/class" type="java.lang.String" value="com.acme.auth.CustomPasswordPolicy" override="false" /> 1
 <Environment name="cms/tool/userPasswordPolicy" type="java.lang.String" value="acme" override="false" />

 <Environment name="dari/authenticationPolicy/acme/class" type="java.lang.String" value="com.acme.auth.CustomAuthenticationPolicy" override="false" /> 2
 <Environment name="cms/tool/authenticationPolicy" type="java.lang.String" value="acme" override="false" /> 

 <Environment name="acme/loginAttemptLimit" type="java.lang.String" value="5" override="false" /> 3
 <Environment name="acme/passwordHistoryLimit" type="java.lang.String" value="10" override="false" /> 4
