Domains

Overview

In Redtrust, a domain defines the authentication method for a group of users to access the service. The available authentication methods depend on how users are configured to authenticate, as outlined in the table below. Multiple domains can be defined to accommodate multiple use cases. For example, a SAML domain could be created for an organization's users/groups from an IdP like Entra ID (formerly knows as Azure Active Directory) using the Windows Agent in attended mode, while a separate local users domain could be created to authenticate a Linux build server.

Authentication source	Admin console	Windows agent (attended)	Windows agent (unattended)	Linux agent (attended)
Activation code		✅	✅
Entra ID	✅*	✅
Certificate users	✅		✅
LDAP	✅*	✅
Local users (Username/Password)	✅	✅	✅	✅
OAuth	✅	✅
SAML 2.0	✅	✅

* Users authenticate against the domain using their username and password.

General configuration options

You can access the domain creation wizard by navigating to Access > Domain and clicking on the New button. In the wizard you must define the domain's features.

Option	Description
Alias	Defines what users will use to reference this domain when logging in to the service. For example, with a local users domain, a user with the username of John would login to the domain with an alias name of myDomain by entering John@myDomain. For SAML and OAuth domains the Alias can match the email domain of the users. For example, for an organization with emails formatted first.last@companyname.com, the alias could be companyname.com.
Type	Valid domain types include: Activation code Entra ID Certificate users> LDAP Local users (Username & Password) OAuth 2.0 SAML 2.0 .
Access to Personal Area	Defined whether the users of this domain can access their personal area.

See UI screenshot

Other configuration options appear when selecting a domain type.

Option	Description
Concurrency Per User	Setting for the domain to allow a single user to authenticate into multiple agent sessions simultaneously. This can be useful for short lived build pipelines and service accounts.
Limit Users	This field is optional. It's a limit on the number of users that a given domain can be configured with.
SSO Login	This button allows users to go directly to the Identity Provider (IdP). This feature applies to both SAML and OAuth 2.0 domains. If needed, multiple domains can be configured this way, enabling authentication with multiple IdPs directly from the login page.

Entra ID and LDAP configuration

When choosing an Entra ID (formerly Active Directory) or LDAP type domain, new configuration options are immediately displayed in the window:

See UI screenshot

Option	Description
Host	Defines the server address.
Base	Base DN from which the repository is visible to Redtrust. For example DC=Redtrust,DC=com.
Filter	Filter used for user searches in the directory. The string FILTER_PARAM represents the search term. A typical filter: (&(|(cn=*FILTER_PARAM*)(userPrincipalName=*FILTER_PARAM*)(sAMAccountName=*FILTER_PARAM*))(objectCategory=person)). Example: Searching for User1 replaces FILTER_PARAM with User1.
Groups filter	(Entra ID only) Filter used for group searches in the directory. The string FILTER_PARAM represents the search term. A typical filter: (&(cn=*FILTER_PARAM*)(objectCategory=group)).
Query user	User to connect to the external directory.
Password	Password for the query user.
Secure connection	Indicates whether the connection to the Entra ID server uses HTTP (not secure) or HTTPS (secure) protocol.

Local users

See UI screenshot

Option	Description
Minimum length	The minimum required length of passwords.
Use uppercase	Require passwords to include uppercase characters.
Use numbers	Require passwords to include numeric characters.
Use symbols	Require passwords to include special characters.
Password expiration	This option sets a number of months before a password expires.
Account lockout	No lockout: No limit on password attempts. Temporary lockout: Set a configurable number of attempts and a time (in seconds) to temporarily lockout the account. Permanent lockout: Set a configurable number of attempts before locking out the account. An administrator must reset locked-out accounts.

OAuth

See UI screenshot

Option	Description
General
Client ID	App identifier. Provided by your IdP.
Secret client	App authentication key. Provided by your IdP.
Authorization URL	Endpoint to login and consent. Provided by your IdP.
Token URL	Endpoint to exchange for access token. Provided by your IdP.
User information URL	Endpoint to fetch user data. Provided by your IdP.
Automatic provisioning of users	If enabled, this setting imports a user's email, name, and group membership in Redtrust the first time the user authenticates against the IdP. If this setting isn't enabled, you need to manually populate these data fields for users.
Attribute mapping
Name	The value you have configured for the name attribute from your IdP.
Last name	The value you have configured for the last name attribute from your IdP.
Use groups	Enable to have Redtrust use a user's group membership in the claim.
Groups	The value you have configured for the groups attribute from your IdP.
Email	The value you have configured for the email attribute from your IdP.
Use email as user identifier	Enable this option if your organization uses the email attribute as the identifier for users instead of the username. Note: This option needs to be configured at the time of domain creation. It isn't possible to edit this property once a domain has been created.
Username	The value you have configured for the username attribute from your IdP. This option is only available if you don't enable Use email as user identifier.

SAML 2.0

See UI screenshot

Option	Description
General
SP EntityID	This value should be https://REDTRUST_DEPLOYMENT_URL/ALIAS_OF_YOUR_DOMAIN. For example, if the alias of your SAML domain is companyname.com this would be https://redtrustdeployment.com/companyname.com.
Automatic provisioning of users	If enabled, this setting imports a user's email, name, and group membership in Redtrust the first time the user authenticates against the IdP. If this setting isn't enabled, you need to manually populate these data fields for users.
Login URL (HTTP-redirect)	Redirects users to the IdP for login. Provided by your IdP.
Logout URL (HTTP-redirect)	Redirects users to the IdP for logout. Provided by your IdP.
IDP X.509 certificate (for signature)	Verifies the IdP's digital signatures. Provided by your IdP.
Attribute mapping
Email	The value you have configured for the email attribute in the SAML assertion.
Case sensitive NameID	When enabled this setting treats the NameID field as case sensitive. Enabled by default.
Name	The value you have configured for the name attribute in the SAML assertion.
Surname	The value you have configured for the surname attribute in the SAML assertion.
Use email as user identifier	Enable this option if your organization uses the email attribute as the identifier for users instead of name or surnames. Note: this option needs to be configured at the time of domain creation. It's not possible to edit this property once a domain has been created. Most use cases will want to enable this setting.
ACS by index	Disabled by default. This property specifies how to indicate to the IdP (through the SAML authentication request) the URL that will consume the SAML assertion generated by the IdP. If disabled, AssertionConsumerServiceURL will be added to the authentication request. If enabled, AssertionConsumerServiceIndex will be added in the request. In addition, you must configure the IdP so that the index 0 corresponds to the URL https://REDTRUST_DEPLOYMENT_URL/Auth/SamlConsumer.
Groups	Groups to which the user is assigned.

tip

You may see the error “User found, but doesn't belong to any roles” when attempting to log in to Redtrust after authenticating with the IdP. This is because every user accessing the admin console must be assigned a role and the authenticating user hasn't yet been assigned one by the Redtrust administrator. You can solve this by either having the system admin log in to Redtrust and assign this new user to a role or by using SAML groups to assign an entire group of users to a particular role. This allows those group members to automatically log in.

IdP URL configuration

Users can also be directed to the IdP login page, skipping the Redtrust login page by navigating to a URL with the below configuration. After authenticating, the user is sent back to the Redtrust admin console.

https://REDTRUST_URL/login?domain=DOMAIN_ALIAS

User configuration options

Option	Description
