=head1 SYNOPSIS
This is part of the LearningOnline Network with CAPA project
described at http://www.lon-capa.org.
=head1 NOTABLE SUBROUTINES
=over
=cut
package localenroll;
use strict;
=pod
=item run()
set this to return 1 if you want the auto enrollment to run
Beginning with LON-CAPA version 2.4, use of this routine is
deprecated. Whether or not Autoenroll.pl should run is set
by the Domain Coordinator via "Set domain configuration",
provided in the Domain Management section of the Main menu.
=cut
sub run() {
my $dom = shift;
return 0;
}
=pod
=item fetch_enrollment()
connects to the institutional classlist data source,
reads classlist data and stores in an XML file
in /home/httpd/perl/tmp/
classlist files are named as follows:
DOMAIN_COURSE_INSTITUTIONALCODE_classlist.xml
e.g., msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
where DOMAIN = msu COURSE = 43551dedcd43febmsul1
INSTITUTIONALCODE = fs03nop590001
(MSU's course naming scheme - fs03 = Fall semester 2003, nop =
department name, 590 = course number, 001 = section number.)
fetch_enrollment requires three arguments -
$dom - DOMAIN e.g., msu
$affiliatesref - a reference to a hash of arrays that contains LON-CAPA
courses that are to be updated as keys, and institutional coursecodes
contributing enrollment to that LON-CAPA course as elements in each array.
$replyref - a reference to a hash that contains LON-CAPA courses
that are to be updated as keys, and the total enrollment count in all
affiliated sections, as determined from institutional data as hash elements.
As an example, if fetch_enrollment is called to retrieve institutional
classlists for a single LON-CAPA course - 43551dedcd43febmsul1 which
corresponds to fs03nop590, sections 001, 601 and 602 , and the course
also accommodates enrollment from a crosslisted course in the ost
department - fs03ost580002:
the affiliatesref would be a reference to %affiliates which would be:
@{$affiliates{'43551dedcd43febmsul1'}} =
("fs03nop590001","fs03nop590601","fs03nop590602","fs03ost580002");
fetch_enrollment would create four files in /home/httpd/perl/tmp/.
msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
msu_43551dedcd43febmsul1_fs03nop590601_classlist.xml
msu_43551dedcd43febmsul1_fs03nop590602_classlist.xml
msu_43551dedcd43febmsul1_fs03ost580002_classlist.xml
In each file, student data would be stored in the following format
<student username="smith">
<autharg>MSU.EDU</autharg>
<authtype>krb4</authtype>
<email>smith@msu.edu</email>
<enddate></enddate>
<firstname>John</firstname>
<generation>II</generation>
<groupID>fs03nop590001</groupID>
<lastname>Smith</lastname>
<middlename>D</middlename>
<startdate></startdate>
<studentID>A12345678</studentID>
</student>
with the following at the top of the file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE text>
<students>
(all comment - s removed)
and a closing:
</students>
The <startdate> and the <enddate> are the activation date and expiration date
for this student's role. If they are absent, then the default access start and
default access end dates are used. The default access dates can be set when
the course is created, and can be modified using the Automated Enrollment
Manager, or via the 'Upload a class list','Enroll a single student' or
'Modify student data' utilities in the Enrollment Manager, by checking the
'make these dates the default for future enrollment' checkbox. If no default
dates have been set, then the tudent role will be active immediately, and will
remain active until the role is explicitly expired using ENRL -> Drop students.
If dates are to included in the XML file, they should be in the format
YYYY:MM:DD:HH:MM:SS (: separators required).
If there were 10 students in fs03nop590001, 5 students in fs03nop59o601,
8 students in fs03nop590602, and 2 students in fs03ost580002,
then $$reply{'43551dedcd43febmsul1'} = 25
The purpose of the %reply hash is to detect cases where the institutional
enrollment is 0 (most likely due to a problem with the data source).
In such a case, the LON-CAPA course roster is left unchanged (i.e., no
students are expired, even if automated drops is enabled.
fetch_enrollment should return a 0 or 1, depending on whether a connection
could be established to the institutional data source.
0 is returned if no connection could be made.
1 is returned if connection was successful
A return of 1 is required for the calling modules to perform LON-CAPA
roster changes based on the contents of the XML classlist file(s), e,g,,
msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
XML classlist files are temporary. They are deleted after the enrollment
update process in the calling module is complete.

=item get_sections()
This is called by the Automated Enrollment Manager interface
(lonpopulate.pm) to create an array of valid sections for
a specific institutional coursecode.
e.g., for MSU coursecode: fs03nop590
("001","601","602") would be returned
If the array returned contains at least one element, then
the interface offerred to the course coordinator, lists
official sections and provides a checkbox to use to
select enrollment in the LON-CAPA course from each official section.
get_sections takes two arguments - (a) the institutional coursecode
(in the MSU case this is a concatenation of semester code, department
and course number), and (b) the LON-CAPA domain that contains the course.
If there is no access to official course sections at your institution,
then an empty array is returned, and the Automated Enrollment Manager
interface will allow the course coordinator to enter section numbers
in text boxes.
=cut
sub get_sections {
my ($coursecode,$dom) = @_;
my @secs = ();
return @secs;
}
=pod
=item new_course()
This is called by loncreatecourse.pm and
lonpopulate.pm to record that fact that a new course section
has been added to LON-CAPA that requires access to institutional data
At MSU, this is required, as institutional classlists can only made
available to faculty who are officially assigned to a course.
The new_course subroutine is used to check that the course owner
of the LON-CAPA course is permitted to access the institutional
classlist for any course sections and crosslisted classes that
the course coordinator wishes to have affiliated with the course.
If access is permitted, then 'ok' is returned.
The course section or crosslisted course will only be added to the list of
affiliates if 'ok' is returned.
new_course takes three arguments -
(a) the institutional courseID (in the MSU case this is a concatenation of
semester code, department code, course number, and section number
e.g., fs03nop590001).
(b) the course owner. This is the LON-CAPA username and domain of the course
coordinator assigned to the course when it is first created, in the form
username:domain
(c) the LON-CAPA domain that contains the course
=cut
sub new_course {
my ($course_id,$owner,$dom) = @_;
my $outcome = 'ok';
return $outcome;
}
=pod
=item validate_courseID()
This is called whenever a new course section or crosslisted course
is being affiliated with a LON-CAPA course (i.e., by loncreatecourse.pm
and the Automated Enrollment Manager in lonpopulate.pm).
A check is made that the courseID that the course coordinator wishes
to affiliate with the course is valid according to the institutional
schedule of official classes
A valid courseID is confirmed by returning 'ok'
validate_courseID takes two arguments -
(a) the institutional courseID (in the MSU case this is a concatenation of
semester code, department code, course number, and section number
e.g., fs03nop590001).
(b) the LON-CAPA domain that contains the course
=cut
sub validate_courseID {
my ($course_id,$dom) = @_;
my $outcome = 'ok';
return $outcome;
}
=pod
=item validate_instcode()
This is called when a request is being made for an official course.
A check is made that the institutional code for which a course is
is being requested is valid according to the institutional
schedule of official classes.
If the username of the course owner is provided, a more restrictive
test is used, namely that the requestor is listed as instructor of
record for the course in the institution's course schedule/database.
validate_instcode takes three arguments -
(a) the LON-CAPA domain that will contain the course
(b) the institutional code (in the MSU case this is a concatenation of
semester code, department code, and course number, e.g., fs03nop590.
(c) an optional institutional username for the course owner.
An array is returned containing (a) the result of the check for a valid
instcode, and (b) an (optional) course description.
A valid instcode is confirmed by returning 'valid'.
If no course description is available, '' should be set as
the value of the second item in the returned array.
=cut
sub validate_instcode {
my ($dom,$instcode,$owner) = @_;
my $outcome = '';
my $description = '';
return ($outcome,$description);
}
=pod
=item validate_crsreq()
This is used to check whether a course request should be processed
automatically, or held in a queue pending administrative action at
the institution.
Course requests will trigger this check if the process type has been set
to 'validate' for the course type (official, unofficial or community) and
the requestor's affiliation. Whether "validate" is an available option
in the Domain Configuration menu is controlled by auto_courserequest_checks().
One scenario is where the request is for an official course, in which case
a check could be made that the requestor is listed as instructor of
record for the course in the institution's course schedule/database.
Other scenarios are possible, and the routine can be customized according
to whatever rules a domain wishes to implement to run validations against
given the data passed in to the routine.
validate_crsreq takes six arguments -
(a) the LON-CAPA domain that will contain the course.
(b) the username:domain for the course owner.
(c) the course type (official, unofficial or community)
(d) a comma-separated list of institutional affiliations of
the course owner.
(e) the institutional code (in the MSU case this is a concatenation of
semester code, department code, and course number, e.g., fs03nop590.
(f) a comma-separated list of institutional sections included in
the course request (only applicable to official courses).
A valid courserequest is confirmed by returning 'process'.
The following can be returned: process, rejected, pending, approval or error (with error condition - no :), followed by a : and then an optional message.
(a) process - the requestor is the recorded instructor - create the course
(b) rejected - the requestor should never be requesting this course, reject the
request permanently
(c) pending - the requestor is not the recorded instructor, but could
become so after administrative action at the institution. Put the
request in a queue and check localenroll:validate_instcode()
periodically until the status changes to "valid".
(d) approval - the request will be held pending review by a Domain Coordinator.
(e) error (followed by the error condition).
=cut
sub validate_crsreq {
my ($dom,$owner,$crstype,$inststatuslist,$instcode,$instseclist) = @_;
my $outcome = 'approval';
return $outcome;
}
=pod
=item crsreq_checks()
This is used to determine whether the "validate" option should appear in the
possible choices for course request processing in the Domain Configuration
menu for Course Requests. Ultimately it is called by domainprefs.pm (via:
lonnet -> lond -> localenroll.pm) The domain configuration menu includes
a table where columns are course type (official, unofficial or community)
and rows are institutional affiliations (e.g., Faculty, Staff, Student etc.).
crsreq_checks() takes three arguments: $dom, $reqtyes, $validations.
$dom - the domain for which validation options are needed.
$reqtypes - ref to an ARRAY of course types (i.e., official, unofficial and community.
$validations - ref to a hash of a hash which will determine whether "validate"
will be one of the possible choices for each course type (outer hash key),
and institutional type (inner hash key).
For example to allow validate to be a choice for official classes for Faculty,
req_checks would include:
$validations{'official'}{'Faculty'} = 1;
This routine is closely tied to validate_crsreq(). "Validate" should not be
a possible choice in the domain configuration menu for a particular course
type/institutional affiliation, unless a corresponding validation code has
been implemented in validate_crsreq().
For example at MSU, official courses requested by Faculty will be validated
against the official schedule of classes to check that the requestor is one
of the instructors of record for the course. In this case validate_crsreq()
includes a call to validate_instcode().
=cut
sub crsreq_checks {
my ($dom,$reqtypes,$validations) = @_;
if ((ref($reqtypes) eq 'ARRAY') && (ref($validations) eq 'HASH')) {
my (%usertypes,@order);
if (&inst_usertypes($dom,\%usertypes,\@order) eq 'ok') {
foreach my $type (@{$reqtypes}) {
foreach my $inst_type (@order) {
$validations->{$type}{$inst_type} = 0;
}
}
}
}
return 'ok';
}
=pod
=item create_password()
This is called when the authentication method set for the automated
enrollment process when enrolling new users in the domain is "localauth".
This could be signalled for the specific user by the value of localauth
for the <authtype> tag from the classlist.xml files, or if this is blank,
the default authtype, set by the domain coordinator when creating the course
with loncreatecourse.pm.
create_password takes three arguments -
(a) $authparam - the value of <autharg> from the classlist.xml files,
or if this blank, the default autharg, set by the domain coordinator when
creating the course with loncreatecourse.pm
(b) $dom - the domain of the new user.
(c) $username - the username of the new user (currently not actually used)
Four values are returned:
(a) the value of $authparam - which might have been changed
(b) a flag to indicate whether a password had been created
0 means no password created
1 means password created. In this case the calling module - Enrollment.pm
will send the LON-CAPA username and password to the new user's e-mail
(if one was provided), or to the course owner (if one was not provided and
the new user was created by the automated process), or to the active
course coordinator (if the new user was created using the 'update roster
now' interface included in the Automated Enrollment Manager).
(c) a flag to indicate that the authentication method is correct - 'ok'.
If $authchk is not set to 'ok' then account creation and enrollment of the
new user will not occur.
(d) if a password was created it can be sent along. This is the password
which will be included in the e-mail sent to the new user, or made available
to the course owner/course coordinator if no e-mail address is provided. If
you do not wish to send a password, but want to give instructions on obtaining
one, you could set $newpasswd as those instructions. (e.g.,
$newpasswd = '(Please visit room 212, ACNS Bldg. to obtain your password)';
The value of $newpasswd is NOT written in the user's LON-CAPA passwd file in
/home/httpd/lonUsers/$dom/a/b/c/abcuser/passwd, which in the case of a user
employing localauth will contain 'localauth:$authparam'. If you need to include
a parameter in the user's passwd file, you should return it as $authparam,
i.e., the first of the variables returned by create_password().

Incoming data: three arguments
(a) $dom - domain
(b) $ruleshash - reference to hash containing rules
(a hash of a hash)
keys of top level hash are short names
(e.g., netid, noncredit)
for each key, value is a hash
desc => long name for rule
rule => description of rule
authtype => (krb5,krb4,int, or loc)
authentication type for rule
authparm => authentication parameter for rule

Prevents errors when undefined subroutines are called in this package
Will allow new routines added in the future to be called from lond etc.
without the need for customized versions of local*.pm packages to be
modified to include the new subroutines immediately.
