There are two ways to add a user to EUM
1) Using the optional Registration Form
The out-of-the-box registration form if deployed is available at <yoursitehost>/landing/register.
The default required fields are First Name, Last Name and Email address.
Depending on the install configuration, the registered user may need to be approved by an approver prior to receiving the welcome email to set their password and login to the system.
2) Add a user via LandingAdmin
Login as user who has access to LandingAdmin (Group Owner, Group Editor, Configuration Editor)
From the Home page of the Extranet User Manager under Users click Add User or click Add then User from the menu.
The out of the box required fields are First Name, Last Name and Email address. Optionally you can specify the Username field. If this field is left blank, the email address is used. For installs where the EUM account is stored in Active Directory (AD), restricted characters such as the '@' are replaced by the '_' character and are truncated to match the AD specification.
Set the user status to 'Active' to send a welcome email to the user.
Optionally, you can add the user to one or more groups if required.
