- Response to incorrect Captcha on account creation page is to display a page
containing a link back to the form, instead of a call to &invalid_state().
- Rules for length and/or characters in a LON-CAPA password (internal auth)
checked server-side when a user self-creates a user account.
- rule-checking code moved from lonpreferences.pm to loncommon.pm to
facilitate reuse.
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.
