If you need to restrict the set of allowed users (e.g. to members of a department) then specify

You can manage user attribute first name, last name, email from ldap:
auth.settings.login_methods.append(ldap_auth(...as usual...,

manage_user - let web2py handle user data from ldap
user_firstname_attrib - the attribute containing the user's first name
optionally you can specify parts.
Example: cn: "John Smith" - 'cn:1' = 'John'
user_lastname_attrib - the attribute containing the user's last name
optionally you can specify parts.
