Configuration records

The Configuration record is where all global settings for a Domino installation are listed.

  1. Go to the Admin portal.

  2. Click Platform settings > Configuration records.

  3. On the Configuration records page, you can:

    • Click an existing record to edit its attributes.

    • Click Add Record to create a new setting. If no record is created in the application, the system uses the default value.

      You must restart the Domino services for changes to take effect.

    Important
    		 Any configuration that is designated as a secret will have its corresponding value obfuscated. A placeholder text ******** will be displayed instead of the actual value to enhance security and prevent inadvertent exposure.

Restart services

Configuration record is read by Domino services at process startup time. So, for configuration record changes to take affect, you must restart the Domino services. One way to do this is by clicking the restart services link in the Configuration records page.

You can also use a CLI tool like kubectl instead of the Domino UI to restart services. When doing so, ensure that you restart:

  1. Every nucleus-* deployment.

  2. Each data-plane-agent in the local and (if applicable) remote data planes.

Authentication

Idle Timeout configuration

These options relate to automatic session management through the Idle Timeout functionality. When users remain inactive across all Domino tabs for a specified period, the system will automatically log them out of their entire session for enhanced security. This intelligent timeout mechanism monitors actual user interaction rather than just session duration, providing better security without disrupting active work.

KeyDefaultDescription

com.cerebro.domino.frontend.idleTimerValueInMinutes

0

This is the total inactivity time in minutes after which the user will be automatically logged out. The default value of 0 means that this functionality is turned off.

com.cerebro.domino.frontend.idleTimerPromptValueInMinutes

0

This is the amount of time before the idle timeout when a user will receive an inactivity notice. With the default value of 0, users will be notified 3 minutes before being logged out unless this value is changed. This setting must be less than the value of com.cerebro.domino.frontend.idleTimerValueInMinutes.

  • Data source access secrets

  • Project environment variables

The following configuration settings are used to connect to Vault.

KeyDefaultDescription

Beta feature: Contact your Domino representative for assistance. Used to configure Domino to work with your Vault installation outside the Domino cluster.

This is the path where the Vault token is present. If the .token config key is present, this is ignored.

com.cerebro.domino.vault.auth.token.token

N/A

Beta feature: Contact your Domino representative for assistance. Used to configure Domino to work with your Vault installation outside the Domino cluster.

This is the literal value of the Vault token that overrides the .tokenFile config key.

com.cerebro.domino.vault.auth.token.refreshEvery

An optional path in the key-value store that serves as the root for all Domino-stored secrets.

Web Apps

IFrame Security

Web apps in Domino are served in HTML inline frames, also known as “iframes”. To improve iframe security, a “sandbox” attribute can be set for iframe elements. When this attribute is set, extra security restrictions are applied to the iframes serving web apps in Domino, like blocking cross-origin requests, form submissions, script executions, and much more.

In Domino, this “sandbox” attribute can be toggled with the ShortLived.iFrameSecurityEnabled feature flag. Setting this flag to “TRUE” will apply the sandbox attribute to the iframe and apply the extra security restrictions. If the flag is set to “FALSE”, no security restrictions will be applied to the iframe. By default, in Domino 4.4.1 the ShortLived.iFrameSecurityEnabled flag is set to FALSE.

Important
 This feature flag will be deprecated in future versions of Domino. Domino recommends implementing web app security using content security policies instead (described below).

Content Security Policies

A content security policy allows Domino web apps to access specific, whitelisted external resources. Any request made to non-whitelisted external resources, however, will be blocked.

In Domino, you can toggle this feature with the EnableContentSecurityPolicyforApps feature flag. Setting this flag to “TRUE” will block requests to all non-whitelisted resources and allow requests to whitelisted resources. Setting this flag to “FALSE” will allow all requests to resources (that is, no blocking of any kind). By default, in Domino 4.4.1 the EnableContentSecurityPolicyforApps is set to FALSE.

The keys and default values associated with this feature flag are listed in the table below.

KeyDefaultDescription

com.cerebro.domino.apps.contentSecurityPolicy.whiteListAppHost

true

Whitelist the app’s own host URL for all resource types. This can be toggled to false for an even more stringent security policy. For example, to prevent internal attacks by disabling all JavaScript in web apps, you can set this flag to false and com.cerebro.domino.apps.contentSecurityPolicy.whiteListedScriptSrcList to none or the empty string.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedImageSrcList

data:

Allows images to be inserted directly into a web app using a data: URL. This allows Domino Apps to include images in the app’s HTML without loading the image from an outside resource. Learn more about data: URLs here: Mozilla - Data URLs.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedScriptSrcList

cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js cdn.plot.ly/plotly-latest.min.js 'unsafe-eval' 'unsafe-inline'

Whitelists the URLs of the scripts that the demo Apps in the quick-start project load to display their interactive charts. It also allows an app to define scripts in HTML using the <script> tag. Also allows JavaScript to create more JavaScript as the app runs using the built-in JavaScript function eval.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedStyleSrcList

'unsafe-inline'

Allows apps to define their own styles with <style>, javascript: URLs, and inline <script> elements.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedConnectSrcList

ws:

Allows the app to use WebSockets, which use URLs that begin with ws:, to communicate with other resources.

To whitelist a resource:

  1. Go to Configuration Management (that is, Configuration records) in your Domino admin settings.

  2. Click Add Record.

  3. Set the key to com.cerebro.domino.apps.contentSecurityPolicy.whiteListedConnectSrcList.

  4. Set the value to ws: followed by the URL of the resource you’d like to whitelist (that is, ws: https://foobar.buz.bax/). You must work with your team to figure out which URLs have to be whitelisted. For more details, see: Identify Resources to Whitelist.

  5. Save the record and restart Domino services.

IFrame Security in combination with Content Security Policies

In Domino 4.4.1, the ShortLived.iFrameSecurityEnabled and EnableContentSecurityPolicyforApps feature flags coexist. The matrix below describes the blocking behavior for requests based on both feature flags.

Important

The IFrame feature flag will be deprecated in future versions of Domino. Domino recommends implementing web app security using content security policies instead.

ShortLived.iFrameSecurityEnabled = FALSEShortLived.iFrameSecurityEnabled = TRUE

EnableContent SecurityPolicyForApps = FALSE
