more users have same email address

Until now the email address needs to be unique. this issue allows several users to have the same email address or a user who has no email address.

Following configuration and business rules

• configuration in administration if email address needs to be a mandatory field or optional, and if it needs to be unique
• information about activating internal email
• authentication with email not possible (Web, WebDAV, REST, LDAP etc.)
• reset password not possible with email --> SMS web service recommended

without email address

• send email always to OO-Email
• do not send emails to users without email address (e.g. bulk sending)
• do not send notifications to internal mailbox
• deactivate external options, which are connected to the email (e.g. virtual classroom)

Adaptions

• configuration in admin
• adapt UserManager / BaseSecurity Modul Queries and UnitTests

• REST API User PUT / GET
• Usermanagement: User Erstell Form
• Usermanagement: User Excel Import
• Login process for Web, WebDAV, LDAP ...
• Course / groups: add members
• Mailmodul
• check all elements, add checks 
• adapt wording (e.g. info on login screen)
