- Self-creation of user accounts using e-mail verification.
- User can be prompted to choose affiliation (e.g., instructor, student,
other etc.).
- User can be given option to choose a username, while e-mail address
still used for verification. A required e-mail domain can be set.
- Domain Coordinator can display user-selected status and user's e-mail
address when choosing to approve queued account requests.
1: # The LearningOnline Network
2: # Allow visitors to create a user account with the username being either an
3: # institutional log-in ID (institutional authentication required - localauth,
4: # kerberos, or SSO) or an e-mail address. Requests to use an e-mail address as
5: # username may be processed automatically, or may be queued for approval.
