1.1     ! raeburn     1: \label{Domain_Configuration_User_Creation}
        !             2: Identity management in a LON-CAPA domain is dependent on settings
        !             3: made for user creation and user modification. Of particular concern
        !             4: is the potential for assignment of usernames in a format used by your
        !             5: institution when the username does not yet exist. In such a case,
        !             6: authentication is likely to be set to be \char`\"{}internal\char`\"{},
        !             7: and should a real user be created in the future, and be enrolled in
        !             8: a course by auto-enrollment, the user would either be unable to authenticate
        !             9: (using LON-CAPA log-in page), or would be authenticated by SSO, and
        !            10: have access to the original user's roles and associated information.
        !            11: 
        !            12: It is important therefore to establish format rules for new usernames
        !            13: so the only users created with institutional-type usernames are the
        !            14: real users themselves with the appropriate authentication type (Kerberos
        !            15: or localauth). Even without format rules, the Domain Coordinator can
        !            16: set who can create new users, and the authentication types that may
        !            17: be set in different context.
        !            18: 
        !            19: The domain-wide options available for user creation are: 
        !            20: 
        !            21: \begin{itemize}
        !            22: \item Activate/deactivate operation of format rule(s) for usernames 
        !            23: \item Activate/deactivate opration of format rule(s) for student/employee
        !            24: IDs 
        !            25: \item Activate/deactivate operation of format rule(s) which prohibit self-created
        !            26: accounts using certain types of e-mail address as the username.
        !            27: \item Control which types of username (official or non-official) may be
        !            28: used when creating new users in course or author context 
        !            29: \item Control which types of user may create their own accounts in LON-CAPA 
        !            30: \item Control which types of authentication may be used when assigning authentication
        !            31: to new users in author, course or domain context
        !            32: \end{itemize}
        !            33: The format rules themselves are defined by customizing the following
        !            34: routines in localenroll.pm: 
        !            35: 
        !            36: \begin{itemize}
        !            37: \item usernames: \&username\_rules() and \&username\_check()
        !            38: \item IDs: \&id\_rules() and \&id\_check()
        !            39: \item self-created accounts: \&selfcreate\_rules() and \&selfcreate\_check()
        !            40: \end{itemize}
        !            41: The first two of these - username and ID check, when enforced, require
        !            42: that if a username and/or ID of the activated formats is to be used
        !            43: in LON-CAPA, they must exist in the institutional directory. If they
        !            44: exist, the corresponding user information (first name, middle name,
        !            45: last name, e-mail address) will be used when creating the new user
        !            46: account. If they do not exist, account creation will not occur.
        !            47: 
        !            48: The third one operates in the opposite manner - if a user attempts
        !            49: to self-create an account employing a username with an e-mail address
        !            50: in a format which matches the rule, the action does not proceed, and
        !            51: the user is directed to create an account with the corresponding institutional
        !            52: log-in. In this case account creation can only occur once the user
        !            53: has authenticated using that login.
