In email authentication, a user receives an email from A3 with a validation link to click on to complete registration. An email authentication source is predefined in the external authentication sources list.

Note

The use of email authentication requires that SMTP servers and other parameters be configured. This can be accomplished through the use of the Alerting page.

The fields in the form are:

Field Name	Usage	Example
Name	The name of the authentication source.	email-auth
Description	A description of the purpose of the authentication source.	Email-based identification in web portal
Banned Domains	A comma-separated list of domains that are banned for email registration. Wild cards are allowed. Banned domains are checked before allowed domains.	*gmail.com
Allowed Domains	A comma-separated list of domains that are allowed for email registration. Wild cards are allowed. Banned domains are checked before allowed domains.	extremenetworks.com
Email Activation Timeout	Since the user must view an email to activate the validation link, a temporary VLAN or other network configuration is automatically instantiated that allows internet access for a period of time. The length of that time is specified here.	10 minutes
Allow Local Domain	If enabled, all email addresses with any domain are allowed to perform email authentication. If not enabled, email addresses with a domain name that matches the domain associated with A3 will NOT be allowed.
Host in Activation link	If used, the host name used in the validation link will be replaced. Note: If this field is used, then the haproxy service must be restarted via the Status>Services page. Further, the hostname used must have a DNS entry in the user VLAN.
Create Local Account	If enabled, when a user completes an email authentication a local A3 account will be created for the user if one does not already exist.
Password Hashing Method	The algorithm used to hash passwords in the database. Only new or reset passwords are affected. One of Bcrypt, Plaintext, or NTLM.
Password Length	The length of generated passwords.	8
Number of Logins for the Local Account	If the Create Local Account field is enabled, then this field designates the number of times that the user or the user's devices may login. A value of 0 means an infinite number of times.	0
