Redmine Single Sign-On (SSO)

---

Redmine SSO (Single Sign-On) is a method that provides secure Single Sign-On access into Redmine using a single set of login credentials. With miniOrange's SSO services, along with Redmine you can also login into other On-Premise and Cloud Applications using your existing Identity Providers/User Store.

With miniOrange Redmine SSO, you can:

• Enable your users to automatically login to Redmine
• Have centralized and easy access control of the users
• Connect easily with any external identity source like Azure AD, ADFS, Cognito, etc

Supported SSO Features

miniOrange Redmine SAML integration supports the following features:

• SP Initiated SSO Login: Users can access their Redmine account via a URL or bookmark. They will automatically be redirected to the miniOrange portal for login. Once they've signed on, they'll be automatically redirected and logged into Redmine.
• IdP Initiated SSO Login: Users need to login to the miniOrange first, and then click on the Redmine icon on the applications dashboard to access Redmine.(If you have set up any more Identity Sources, you will log in to that platform).
• Single Logout: With this feature, you will be automatically logged out of all the applications that are connected with Identity provider (IdP) when you log out from Redmine org or any other app.
• Mandate users to Login using SSO: Single Sign-on can make it mandatory for all users to log in using SSO. This will prevent any person from login using any other source and bypassing the login system. No person will be able to have direct login making it a streamline and secure process.

Prerequisites

Steps to Install redmine omniauth saml plugin in redmine:

• Download redmine omniauth saml plugin from here. Extract the file and store it inside the plugins folder of the redmine root directory.
• To verify you can go to your redmine root directory and check you have a plugins/redmine_omniauth_saml/init.rb file.
• Install dependencies with bundler with bundle install.
• Copy assets by running this command from your redmine root directory (note: the plugin has no migration for now) : RAILS_ENV=production bundle exec rake redmine:plugins
• Restart your Redmine instance (depends on how you host it)
• Copy sample-saml-initializers.rb file from plugins to~redmine_root_directory/config/intializers/. Rename file tosaml.rb (name doesn’t matter as long as file is ruby file). This saml.rb file is used for configuring saml sso with miniorange as mentioned below.
• Go to config/initializers/saml.rb in the redmine root directory.



• In the saml.rb file you can update the following urls : assertion_consumer_service_url, issuer, single_logout_service url, which will be required in step 1 while configuring Redmine with miniOrange.

Follow the step-by-step guide given below for Redmine SSO (Single Sign-On)

1. Configure Redmine in miniOrange

• Login into miniOrange Admin Console.
• Go to Apps and click on Add Application button.



• In Choose Application Type, select SAML/WS-FED from the All Apps dropdown.



• Search for Redmine in the list, if you don't find Redmine in the list then, search for custom and you can set up your application in Custom SAML App.

• Enter Custom Application Name as Redmine.
• Enter the SP Entity ID or Issuer as : http://localhost:3000/saml/metadata
• Enter the ACS URL in the following format : http://localhost:3000/auth/saml/callback
• Enter the Single Logout URL : http://localhost:3000/auth/saml/sls

Note: The http://localhost:3000 should be replaced by your redmine site url.

• Now you will need this additional config.

Source (saml.rb file)	Destination (saml.rb file only)
single_logout_service_url	signout_url
single_logout_service_url	idp_slo_target_url

• Check Sign Response and Sign Assertion depending on your configuration.
• Click on Next to proceed further.



• In the Attribute Mapping tab configure the following attributes as shown in the image below.



• To upload respective app logo for a Custom SAML App, click on Upload Logo tab.



• Click on Save.

To get miniOrange metadata details in order to configure Datto:

• Go to Apps >> Manage Apps.
• Search for your app and click on the select in action menu against your app.
• Click on Metadata to get metadata details, which will be required later.



• Here you will see 2 options, if you are setting up miniOrange as IDP copy the meta details related to miniOrange, if you required to be authenticated via external IDP's (OKTA, AZURE AD, ADFS, ONELOGIN, GOOGLE APPS), you can get the metadata from the 2nd section as shown below.



• Click on the Download Metadata. This will be required in the Redmine dashboard to complete the configuration.

2. Configure Single Sign-On (SSO) in Redmine

• Go to config/initializers/saml.rb in the redmine root directory.
• Now to complete configuration we need to copy URLs and Certificate from miniOrange app metadata to saml.rb file in redmine.

Source (miniOrange metadata)	Destination (saml.rb file in redmine)
SAML Login URL	idp_sso_target_url
X.509 Certificate	idp_cert_fingerprint

• Follow these steps to create fingerprint of the certificate.
• Go to the directory where you downloaded certificate and run this command “openssl x509 -noout -fingerprint -sha1 -in YourSamlAppCert.crt”. (Make sure you have openssl installed on your system). Copy fingerprint generate and paste it against idp_cert_fingerprint in saml.rb file.



• Alternative to above step you can copy certificate from miniorange paste it against idp_cert and comment out fingerprint line.
  :idp_cert => "-----Paste your miniorange cert fingerprint here-----"

Note : Make sure certificate is string format if going for second one.

• Now restart the redmine and try SSO.

Finally, we set up our redmine and did SSO with the redmine omniauth SAML plugin.

3. Test SSO Configuration

Test SSO login to your Redmine account with miniOrange IdP:

Using SP Initiated Login

• Go to your Redmine URL, here you will be either asked to enter the username or click on the SSO link which will redirect you to miniOrange IdP Sign On Page.



• Enter your miniOrange login credential and click on Login. You will be automatically logged in to your Redmine account.

Using IDP Initiated Login

• Login to miniOrange IdP using your credentials.



• On the Dashboard, click on Redmine application which you have added, to verify SSO configuration.

5. Adaptive Authentication with Redmine [This will be released soon]

Adaptive Authentication for Redmine enables administrators to enforce context-aware access policies by evaluating user login conditions such as IP address, device, location and login time. Based on the configured policy, users can be allowed access, challenged with additional verification or denied access. Administrators can also configure email alerts, customize user-facing error messages, review policy settings before deployment and assign adaptive authentication policies to application login policies to strengthen security and prevent unauthorized access.

[Note: The Adaptive Authentication section has been moved from the left navigation menu. You can now access and manage adaptive authentication policies by navigating to Policies >> Adaptive Access Policy.]

A. Restricting access to Redmine with IP Based Access Restriction

IP Based Access Restriction allows administrators to control user access based on the source IP address of the login request. Administrators can configure trusted or restricted IP addresses and IP ranges and define the action to be taken when a user's IP address matches the configured criteria. During authentication, the user's IP address is evaluated against the configured policy and access is either Allowed, Denied or Challenged based on the selected configuration.

You can configure Adaptive Authentication with IP Based Restriction in following way :

• Login to Self Service Console >> Policies >> Adaptive Access Policy section from the left side menu.



• Click on the Create Policy button on the upper right. Add a suitable policy name and click on Create Policy.



• Expand the IP Based Access Restriction section by clicking on the dropdown icon to configure IP-based access rules.



• Click Add IP Range to configure IP addresses or IP ranges for the policy.



• Specify the IP Address that you want to whitelist. For the IP Range other than the whitelisted one, you can select the above setting to reflect.
• Choose either Allow or Deny by selecting the corresponding option from the dropdown. If a user tries to login with the whitelisted IP address, they will always be allowed access.
• We support IP address range in three formats i.e., IPv4, IPv4 CIDR and IPv6 CIDR. You can choose whichever is suitable for you from the dropdown menu.
• You can add multiple IPs or IP ranges by clicking the + Add IP Range button.



• Once the changes are made, click on Next.
• Select Action for Behavior Change, choose the appropriate Action and Challenge Type for the user from that section.




Action for behavior Change Options :




Attribute	Description
Allow	Allow users to authenticate and use services if Adaptive authentication condition is true.
Deny	Deny user authentications and access to services if Adaptive authentication condition is true.
Challenge	Challenge users with one of the three methods mentioned below for verifying user authenticity.




Challenge Type Options:




Attribute	Description
User second Factor	The User needs to authenticate using the second factor he has opted or assigned for such as OTP over SMS PUSH Notification OTP over Email and many more.
KBA (Knowledge-based authentication)	The System will ask the user for 2 of 3 questions he has configured in his Self-Service Console. Only after the right answer to both questions is the user allowed to proceed further.
OTP over Alternate Email	User will receive an OTP on the alternate email they have configured through the Self Service Console. Once the user provides the correct OTP, they are allowed to proceed further.



• Click on Next to continue.

B. Restricting access to Redmine with Device Based Access Restriction

Device Based Access Restriction allows administrators to control user access based on trusted and registered devices. By leveraging device identification and verification mechanisms, administrators can define policies that evaluate the device used during authentication. When a user attempts to log in, the device is assessed against the configured policy and the appropriate action: Allow, Challenge or Deny is applied based on the configured conditions.

You can configure Adaptive Authentication with Device Based Restriction in following way :

• Login to Self Service Console >> Policies >> Adaptive Access Policy section from the left side menu.



• Click on the Create Policy button on the upper right. Add a suitable policy name and click on Create Policy.



• Click on the Dropdown option to expand the Device Based Access Restriction section to configure device-based access controls.



• Turn on the Enable Device Configuration toggle.



• Configure either Agentless Device Restriction or Agent-Based Device Restriction based on your organization's requirements.
• Agentless Device Restriction: Verifies and manages trusted devices without requiring any software or agent installation on the endpoint. It uses browser and device-based identification methods to evaluate device trust and enforce access policies during authentication.
• Agent-Based Device Restriction: Provides enhanced device trust verification by using a lightweight agent installed on managed devices. It enables advanced device validation and risk-based access control to ensure that only trusted devices can access protected resources.



• Click here to get more information about Device Based Restriction.
• Once the changes are made, click on Next.
• Under Action for Behaviour Change, select the appropriate action and challenge type for the policy.



• Click on Next to continue.

C. Restricting access to Redmine with Location Based Access Restriction

In location restrictions, admin configures a list of locations where they want to allow end-users to either login or deny based on the condition set by the admin. When a user tries to login with adaptive authentication enabled, their Location Attributes, such as (Latitude, Longitude and Country Code) are verified against the Location list configured by the admin. Based on this user will be either allowed, challenged or denied.

You can configure Adaptive Authentication with Location Based Restriction in following way :

• Login to Self Service Console >> Policies >> Adaptive Access Policy section from the left side menu.



• Click on the Create Policy button on the upper right. Add a suitable policy name and click on Create Policy.



• Click on the Dropdown to expand the Location Based Access Restriction section to configure location-based access rules.



• Select Register Location if User Completes Challenge to automatically register a user's location after successful challenge verification.
• Click on Add Location.



• In the Search Location field, enter the location name and select the appropriate location from the search results.
• Specify the radius around the selected location and choose the distance unit (KM or Miles). This will be the total area in and around the location we have configured using the Latitude and Longitude points.
• For each configured location, select whether access should be Allowed or Denied.



• You can click on the Add Location button to add more than one location and then follow steps 2-4 as mentioned above.
• Once the changes are made, click on Next.
• Select your Action for behavior Change and Challenge Type for user from the Action for behavior Change Section.



• Click on Next to continue.

D. Restricting access to Redmine with Time Based Access Restriction

In time restriction, admin configures a time zone with Start and End Times for that timezone and users are either allowed, denied or challenged based on the condition in the policy. When an end-user tries to login with the adaptive authentication enabled, their time zone-related attributes such as Time-Zone and Current System Time, are verified against the list configured by the admin and based on the configuration, the user is either allowed, denied or challenged.

You can configure Adaptive Authentication with Time Based Restriction in following way :

• Login to Self Service Console >> Policies >> Adaptive Access Policy section from the left side menu.



• Click on the Create Policy button on the upper right. Add a suitable policy name and click on Create Policy.



• Expand the Time Based Access Restriction section by clicking on the dropdown icon to Time Based Access Restriction rules.



• Enter the Login Window Buffer Time (Minutes) to allow a grace period before the start time and after the end time of the configured login window. If no value is specified, the default buffer time of 0 minutes is applied.
• Click Add Time to create a time-based access rule.



• Select the required Timezone, configure the Start Time and End Time and choose the applicable days.
• For each time-based rule, select whether access should be Allowed or Denied.



• Click on the Add Time to add more than one timezones.
• Once the changes are made, click on Next.
• Select your Action for behavior Change and Challenge Type for user from the Action for behavior Change Section.



• Click on Next to continue.

E. Email Alerts and Custom Email Message

This section handles the notifications and alerts related to Adaptive Access Policy. It provides the following options:

• Send email alerts: Configure the recipients who should receive email notifications when adaptive authentication events occur. Alerts can be sent to administrators, end users or both, depending on your monitoring and security requirements.
• Send email alerts to administrators: Enable this option to notify administrators when configured adaptive authentication events are triggered. You can optionally specify an email address under Administrator's e-mail address to receive alerts to receive alerts; otherwise, alerts are sent to the default administrator account.



• Send email alerts to end users: Enable this option to notify end users when adaptive authentication events affect their login attempts or device registrations.
• Number of Device Registrations Exceeded Allowed Count: When enabled, end users receive an email notification if they attempt to register more devices than the maximum number allowed by the configured device restriction policy. (Available only for end-user notifications.)



• Get email alerts if users login from unknown devices or locations: Admins need to enable this option to enable receiving alerts for different alert options.



Option	Description
Users login from unknown IP addresses, devices or locations	Enabling this option allows you to login from unknown IP addresses or devices and even locations.
Challenge Completed and Device Registered	Enabling this option allows you to send an email alert when an end-user completes a challenge and registers a device.
Challenge Completed but Device Not Registered	Enabling this option allows you to send an email alert when an end-user completes a challenge but do not registers the device.
Challenge Failed	Enabling this option allows you to send an email alert when an end-user fails to complete the challenge.





• In case you want multiple admin accounts to receive alerts, then you can enable the option for admin and then enter the admin emails separated by a ',' in the input field next to Administrator's email to receive alerts label. To enable alerts for the end users, you can enable the End User checkbox.
• In case you want to customize the deny message that the end user receives in case his authentication is denied due to adaptive policy, you can do this by entering the message inside Deny Message text box.

F. Review

Review the configured policy conditions, behavior change actions, email alert settings and custom error messages before creating the adaptive authentication policy. This step provides a consolidated view of all configured settings, allowing you to verify the policy configuration and make any necessary changes before saving.




• Click on Create Policy.

G. Add Adaptive Authentication policy to Redmine

• Login to Self Service Console >> Policies >> App Login Policy.
• Click on Edit icon option for predefined app policy.



• Set your policy in the Policy Name and select Password as First Factor.



• Enable Adaptive Authentication on Edit Login Policy page and select the required restriction method as an option.
• From Select Login Policy dropdown select the policy we created in last step.
• Apply Restrictions Using: Configure how multiple adaptive authentication restrictions should be evaluated during user login.
  • AND: All enabled restrictions must be successfully satisfied for the login attempt to be allowed.
  • OR: At least one enabled restriction must be successfully satisfied for the login attempt to be allowed.



• Adaptive Authentication Restrictions: Configure additional login restrictions and verification conditions to strengthen account security and control user access based on contextual risk factors.
  • IP Restriction: Restrict login access to specific IP addresses or IP ranges for enhanced security.
  • Device Restriction: Allow login access only from trusted or pre-authorized devices.
  • Location Restriction: Control user login access based on geographic location.
  • Time Restriction: Restrict user login access to specific days or time periods.
  • Force MFA On Each Login Attempt: Require users to complete MFA verification during every login attempt regardless of device or session state.

How to add a trusted Device
