HEAD
Move duplicate code in lonauth.pm and createaccount.pm which handles result from createaccount::username_check() into username_check() for both log-in ID and SSO cases.
- additional args ($contact_name $sso_logout) passed to &username_check for SSO case.
- Page for user information data table customized based on availability of data fields, and whther data can be entered (according to $rowcount and $editable args returned from &loncreateuser::personal_data_display().
- If no values are available or editable don't display table.
- If only non-editable values are available - display table with appropriate message.
- If one or more editable values - display table with appropriate message.
If username check reports errors (e.g., 'username' not in institutional database, or 'authtoken' - authtoken could not be set) - display appropriate error reports.
