As a Canvas Catalog admin, you can choose to restrict domains where users can register for a Catalog account by either allowing or blocking domains. If you choose to only allow specified domains for registration, Catalog will only allow users to register for an account using an email address with the specified domain(s). If you choose to block domains, Catalog will not allow users to register for an account if they use an email address with the blocked domain(s).
Subcatalogs inherit the same domain registration restrictions as set for the main Catalog account, unless restrictions are also set for a specific subcatalog.
Open Admin
Click the User Name drop-down menu [1]. Then, click the Admin link [2].
Open Catalogs
Click the Catalogs tab.
Select Catalog
Click the catalog or subcatalog name link.
Manage Domain Registration Restrictions
The Catalog Info page opens by default.
In the Restrictions on Registration Email Domains section, you can manage registration restrictions.
To manage restrictions, select a radio button.
Allow Email Domains
If you choose to allow specified email domains for account registration, you can list domains in the Allowed Registration Email Domain List. To add a domain to the list, enter the domain name and press enter on your keyboard.
Block Email Domains
If you choose to block specified email domains for account registration, you can list domains in the Blocked Registration Email Domain List. To add a domain to the list, enter the domain name and press enter on your keyboard.
View Apply Domain Restriction to Enrollment Option
This provides additional protection for listings by ensuring only users from approved domains can complete the full access process. Current functionality stays the same, unless the option is enabled.
The Apply domain restriction to enrollment option displays in the Email Domain Restrictions for Registration and Enrollment section. Setting the option to Yes ensures that users with unapproved domains cannot enroll in protected listings. If the option remains off, restrictions continue to apply only to registration.
Subcatalogs inherit enrollment restriction rules by default but can override them. When inheritance is enabled, the domain restriction controls are disabled and the inherited setting is displayed. If a subcatalog overrides the parent setting, it can apply its own rule for enrollment restriction.
Note: This enhancement lets you apply domain restrictions to both registration and enrollment, strengthening access control without altering existing behavior, increases protection for protected listings, and supports catalog and subcatalog inheritance for consistent enforcement.
Save Catalog Info
Click the Save button.
View Approved Domain Message
When enrollment restriction is active, a user with a blocked domain who attempts to enroll sees a message indicating that enrollment is limited to approved email domains, and the Enroll button is hidden. This behavior applies to both free and paid listings, respecting catalog and subcatalog configuration.
