By default, anyone who can access the Domino application can create a user account. Sometimes, you must strongly restrict networking access to Domino to prevent unwanted account creation.
If such restrictions are not enough, it is possible to specify a whitelisted domain or set of email addresses and only allow signups when the provided email is on the whitelist. To set a whitelist:
-
Log in to the target deployment as an admin.
-
Click your username in the upper right, then click Admin.
-
Under Advanced, click Central Config.
-
Click Add Record and provide the following:
-
namespace:
common -
name: leave empty
-
key:
com.cerebro.domino.frontend.signupEmailWhitelistOrDomain -
value: the value can be either a domain (e.g.
dominodatalab.com) or a comma-separated list of email addresses
-
-
Click Create, then restart the Domino front-end for your changes to take effect. Users will then only be able to create accounts if the email they provide is on the whitelist or matches the whitelisted domain.
