- Functionality for requesting user information from a user authenticated by a domain's default authentication (must be either Kerberos of localauth) moved to new &username_check() subroutine.
- Remove $reqtime - not used
- Add missing space in message displayed when token information is incomplete.
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: # or kerberos) or an e-mail address.
