OAuth/OpenID Single Sign On (SSO) into Confluence using Google Apps
Confluence OAuth/OpenID app gives the ability to enable OAuth/OpenID Single Sign-On for Confluence. Confluence is compatible with all OAuth/OpenID Providers. Here we will go through a guide to configure SSO between Confluence and your OAuth/OpenID Provider. By the end of this guide, users from your OAuth/OpenID Provider should be able to log in and register to Confluence.
You can refer the steps to configure Google Apps as OAuth Provider with the Confluence OAuth Client from the video or documentation given below
Pre-requisites
To integrate your OAuth/OpenID provider with Confluence, you need the following items:
Confluence should be installed and configured.
Confluence Server is https enabled (optional).
Admin credentials are set up in Confluence.
Valid Confluence Server and Data center Licence.
Download And Installation
Log into your Confluence instance as an admin.
Navigate to the settings menu and Click Manage Apps.
Click Find new apps or Find new add-ons from the left-hand side of the page.
Locate Confluence OAuth/OpenID Connect Single Sign On (SSO), Confluence SSO via search.
Click Try free to begin a new trial or Buy now to purchase a license for OAuth/OpenID Connect for Confluence SSO.
Enter your information and click Generate license when redirected to MyAtlassian.
Click Apply license.
Step 1: Setup Google Apps as OAuth Provider
Login to Google Console: Visit the Google's Developer Console and login to your account.
Click Select a project, then NEW PROJECT, and enter a name for the project, and optionally, edit the provided project ID. Then click on Create button.
Select your project, click on APIs & Services and select OAuth consent screen option.
On the Consent screen page, select the User Type and click on Create. In the next screen, provide Application name and save the changes.
Now go to Credentials, click on Create Credentials and select OAuth Client ID.
Select Web Application as application type.
Click on the Add URI button in Authorized redirect URIs section. Collect the callback URL provided in the plugin and enter it here. Click on Create. The callback URL would be {oauth_client_base_url}/plugins/servlet/oauth/callback
Get Client ID and Client Secret: Copy the client ID and Client Secret to your clipboard, as you will need them when you configure miniOrange plugin.
To send user's group to the client application, you need to enable Admin SDK and API access. For Admin SDK, navigate to the Dashboard and click on ENABLE APIS AND SERVICES.
Now search for Admin SDK, select it from the list and then click on ENABLE button.
To enable API Access you need to login into Google Admin console. In Google Admin Console, go to Security ->Settings.
Look for API Permissions -> Enable API access
Step 2: Setup Confluence as OAuth Client
Enter Client Id, Client Secret and scope as email. And if you also want to fetch group info of the users then enter email https://www.googleapis.com/auth/admin.directory.group.readonly in the scope field.
Verify the Google Administrator Account : Click on Verify Admin Credentials. For fetching the user groups from Google, you need to verify your Google Administrator's Account by clicking on 'Verify Credentials'.
NOTE: You need to login with your Google Administrator's account in this step. If you login with an user account, groups will not be fetched from Google.
If you are unable to fetch Groups then Go to Permissions and click on REMOVE ACCESS
Step 3: User Profile
Click on User Profile from the left sidebar. We will be setting up user profile attributes
for Confluence. If your
users are stored in a directory that is Read Only, please disable the option User
Profile Mapping in the User Profile tab and skip to the step, Matching a User.
a. Finding correct attributes
Go to the SSO Endpoints tab. Scroll down and click on Test
Configuration.
You will see all the values returned by your OAuth/OpenID Provider to Confluence in a table. If you don't see
a value for First Name, Last Name, Email or Username, make the required settings in your OAuth/OpenID
Provider to return this information.
Once you see all the values in Test Configuration, keep the window open and go to the User
Profile tab.
b. Setting profile attributes
In this User Profile tab, fill the values by matching the name of the attribute. For
instance, if the Attribute Name in the Test Configuration window is NameID, enter NameID against
Username.
Setting up both Username and Email is required if you want to let users register. You can allow only
existing users to log in, by unchecking the Allow User Creation attribute in the
Advance SSO Options tab.
c. Matching a User
When the user logs into Confluence, one of the user's data/ attributes coming in from the OAuth/OpenID Provider
is used to search the user in Confluence. This is used to detect the user in Confluence and log in the user to the
same account.
Go to the User Profile tab.
Select Username or Email for Login Confluence user account by.
Enter the attribute name from OAuth/OpenID Provider which corresponds to Username or Email using
Finding Correct Attributes.
d. Custom Attribute Mapping
The custom attributes received in the OAuth/OpenID response can be configured using the
Configure User Properties(Extended Attributes) section.
Click Add Attribute Mapping.
Enter the attribute name (E.g. department) as User Property Key in the Select Confluence Attribute to
Map field.
Corresponding to this key, fill the attribute value you receive from the Test Configuration window into
Attributes from IDP tab. For instance, if the Attribute Name in the Test Configuration
window is Department, enter Department as the Attribute Value.
Another attribute e.g. location can be added by clicking on Add Attribute Mapping
option.
Step 4: User Groups
We will be setting up user group attributes for Confluence. If you want to enable group mapping then you will need to
select please check Eisable Group Mapping in the User Groups tab else you can skip to Setting
default
group.
a. Setting default group
Select the users' Default Group in the tab User Groups. If no group is
mapped, users are added by default to this group.
You can enable default groups for All Users or New Users using the
option Assign Default Group To. Select None if you don't want to
assign any default group to SSO users.
b. Finding Group Attribute
Just like we found Attribute Name for User Profile attributes, we can find group attributes. Go to the
Configure OAuth tab and click on Test Configuration.
You will see all the values returned by your OAuth/OpenID Provider to Confluence in a table. If you don't see
value with groups, make the required settings in your OAuth Provider to return group names.
Once you see all the values in Test Configuration, keep the window open and go to the User
Groups tab.
Enter the Attribute Name of the group against Group Attribute.
Check Disable Group Mapping option if you don't want to update groups of existing
users.
c. Group Mapping
Group Mapping can be done in two ways:
Manual group mapping: If the names of groups in Confluence are different from the
corresponding groups in OAuth/OpenID Provider, then you should use Manual group
mapping.
On-The-Fly group mapping: If the names of groups in Confluence and OAuth/OpenID Provider are
the same, you should use On-The-Fly group mapping.
I. Manual Group Mapping
Check Allow User Creation based on Group Mapping option if you want new users to be
created only
if at least one of the user's OAuth/OpenID Provider groups is mapped to a group in the application.
For mapping, first select a Confluence group from the dropdown which lists all groups present in Confluence and then
enter the name of the OAuth/OpenID Provider group to be mapped in the textbox Groups from
Application.
For example, if you want all users in 'dev' group of OAuth/OpenID Provider to be added to
Confluence-software-users, you will need to select Confluence-software-users from the dropdown and enter 'dev'
against Confluence-software-users.
Use '+' and '+10' buttons to add extra mapping fields. Use the '-'
button next to each
mapping to delete that mapping.
II. On-The Fly Group Mapping
Check Create New Groups option if you want new groups from OAuth/OpenID Provider to be
created if not found in Confluence.
You can preserve existing user groups by selecting the Keep Existing User Groups
option. Unticking this option will result in the user being removed from a group in Confluence if that group
is not present in the OAuth/OpenID response returned by the OAuth/OpenID provider.
If you don't want On-The-Fly group mapping to affect Confluence groups which are managed locally, then
deselect the option Keep Existing User Groups and add those groups in the
Exclude Groups field.
Step 5: SSO Settings
The settings in the SSO Settings tab define the user experience for Single Sign On.
a.Sign In Settings
Enable Auto Redirect to Application feature to redirect users to an OAuth/OIDC provider
when the Confluence login page is accessed. You can even set the delay before redirecting to the provider.
Enable Backdoor Login will allow you to use a backdoor URL in case of an emergency. You can
even restrict access to backdoor URL for specific groups using Restrict Backdoor URL
Access feature.
Use Domain Restriction to allow login to only a specific set of users. You can configure
multiple domains (semicolon-separated).
For example, if only 'miniorange.com' and 'gmail.com' domains are allowed then, the user test@miniorange.com
and test@gmail.com will be able to log in and user test@yahoo.com will not be able to log in.
Secure Admin Login Option will ensure reauthentication of admin user before accessing the
pages with administrative permissions.
Secure Admin Login Option can be enabled to ensure the admins will also log in via SSO.
b. Redirection Rules
This section lets you set rules to redirect users to the login page/providers based on their email domains.
This feature is more useful in case you have multiple providers configured. For example, You can set a rule
of checking domain name while logging in and redirect users to different providers. You can add a rule by
clicking on the Add Rule button.
When a rule such as given above is configured example, a login form will be displayed to the users where
they will have to input their Username/email address.
Here you can set domain-based rules for redirecting users to the specific provider. Also, you can set the
default rule that will execute if the condition of any other rule does not satisfy.
c. Seesion Management
Enable User Session Management option to set Remember Me-Cookie to keep users logged in until they are explicitly logged out.
d. Global SSO Settings
SSO can be enabled/disabled from the Global SSO Settings tab in the left sidebar. You can
enable SSO for
Confluence software and service desk using options Enable SSO for Confluence Software and
Enable SSO for Confluence Service
Desk.
If you want to enforce SSO to the Service Desk Agents only then you can select the Enable SSO Only
For ServiceDesk Agents option.
You can change additional settings as Allow Users to Change Password, Restrict access to plugin APIs and
Auto Activate Users on SSO.
You can enable Set Remember Me-Cookie in the Session Management tab to keep users logged in
until they are explicitly logged out.
e. Look and Feel
These settings will allow you to change the look and feel of the login page and error message. To access
these settings click on the Look and Feel tab from the left sidebar.
You can customize the default login button text as well as you can completely design the login page using a
customizable template.
You can also have a custom login page and template for customer portal.
The SSO Error Message section allows you to modify how error messages will be displayed to
your users.
If you want to redirect users to an URL after they log out then you can use Custom Logout
URL under Post Logout Configuration tab.
Similar to the customizable login template, you can also design the Logout page to improve the user
experience.
