With Asset Bank it is possible to allow users with certain email domains (called 'internal' users) to be automatically approved after registering. To enable this feature, you will need to make the following settings changes:

users-can-register-without-approval=true

This can be a single email domain or multiple email domains separated by commas.

local-registration-email-domains=domain1.co.uk,domain2.com,domain3

Users who have an email domain other than those listed above are called 'external' users

external-users-can-register-without-approval=false
