- Bug 6646
- Self-creation of user accounts with e-mail address as username.
- User information and password requested from prospective user in a single
web form.
- Add routines to handle creation of user accounts and notification
following approval by Domain Coordinator.
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.
