   54: 
   55:  Beginning with LON-CAPA version 2.4, use of this routine is
   56:  deprecated.  Whether or not Autoenroll.pl should run is set
   57:  by the Domain Coordinator via "Set domain configuration",
   58:  provided in the Domain Management section of the Main menu.

   71: 
   72:  connects to the institutional classlist data source,
   73:  reads classlist data and stores in an XML file
   74:  in /home/httpd/perl/tmp/
   75: 
   76:  classlist files are named as follows:
   77: 
   78:  DOMAIN_COURSE_INSTITUTIONALCODE_classlist.xml
   79: 
   80:  e.g., msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
   81:  where DOMAIN = msu  COURSE = 43551dedcd43febmsul1 
   82:  INSTITUTIONALCODE = fs03nop590001 
   83:  (MSU's course naming scheme - fs03 = Fall semester 2003, nop =
   84:  department name, 590 = course number, 001 = section number.)
   85: 
   86:  fetch_enrollment requires three arguments -
   87:  $dom - DOMAIN e.g., msu
   88:  $affiliatesref - a reference to a hash of arrays that contains LON-CAPA 
   89:  courses that are to be updated as keys, and institutional coursecodes 
   90:  contributing enrollment to that LON-CAPA course as elements in each array.
   91:  $replyref - a reference to a hash that contains LON-CAPA courses
   92:  that are to be updated as keys, and the total enrollment count in all 
   93:  affiliated sections, as determined from institutional data as hash elements. 
   94: 
   95:  As an example, if fetch_enrollment is called to retrieve institutional
   96:  classlists for a single LON-CAPA course - 43551dedcd43febmsul1 which 
   97:  corresponds to fs03nop590, sections 001, 601 and 602 , and the course
   98:  also accommodates enrollment from a crosslisted course in the ost
   99:  department - fs03ost580002:
  100: 
  101:  the affiliatesref would be a reference to %affiliates which would be:
  102: 
  103:  @{$affiliates{'43551dedcd43febmsul1'}} =
  104:    ("fs03nop590001","fs03nop590601","fs03nop590602","fs03ost580002");
  105: 
  106:  fetch_enrollment would create four files in /home/httpd/perl/tmp/.
  107:  msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
  108:  msu_43551dedcd43febmsul1_fs03nop590601_classlist.xml
  109:  msu_43551dedcd43febmsul1_fs03nop590602_classlist.xml
  110:  msu_43551dedcd43febmsul1_fs03ost580002_classlist.xml
  111: 
  112:  In each file, student data would be stored in the following format
  113:  
  114:  <student username="smith">
  115:   <autharg>MSU.EDU</autharg>
  116:   <authtype>krb4</authtype>

  134: 
  135:  and a closing:
  136: </students>
  137: 
  138:  The <startdate> and the <enddate> are the activation date and expiration date
  139:  for this student's role. If they are absent, then the default access start and
  140:  default access end dates are used. The default access dates can be set when 
  141:  the course is created, and can be modified using the Automated Enrollment
  142:  Manager, or via the 'Upload a class list','Enroll a single student' or 
  143:  'Modify student data' utilities in the Enrollment Manager, by checking the 
  144:  'make these dates the default for future enrollment' checkbox. If no default 
  145:  dates have been set, then the tudent role will be active immediately, and will 
  146:  remain active until the role is explicitly expired using ENRL -> Drop students. 
  147:  If dates are to included in the XML file, they should be in the format
  148:  YYYY:MM:DD:HH:MM:SS (: separators required).
  149: 
  150:  If there were 10 students in fs03nop590001, 5 students in fs03nop59o601, 
  151:  8 students in fs03nop590602, and 2 students in fs03ost580002,
  152:  then $$reply{'43551dedcd43febmsul1'} = 25
  153: 
  154:  The purpose of the %reply hash is to detect cases where the institutional 
  155:  enrollment is 0 (most likely due to a problem with the data source).
  156:  In such a case, the LON-CAPA course roster is left unchanged (i.e., no
  157:  students are expired, even if automated drops is enabled.
  158:  
  159:  fetch_enrollment should return a 0 or 1, depending on whether a connection
  160:  could be established to the institutional data source.
  161:  0 is returned if no connection could be made.
  162:  1 is returned if connection was successful
  163: 
  164:  A return of 1 is required for the calling modules to perform LON-CAPA
  165:  roster changes based on the contents of the XML classlist file(s), e,g,,
  166:  msu_43551dedcd43febmsul1_fs03nop590001_classlist.xml
  167: 
  168:  XML classlist files are temporary. They are deleted after the enrollment 
  169:  update process in the calling module is complete.

  188:  (lonpopulate.pm) to create an array of valid sections for 
  189:  a specific institutional coursecode.
  190:  e.g., for MSU coursecode: fs03nop590
  191:  ("001","601","602") would be returned
  192: 
  193:  If the array returned contains at least one element, then 
  194:  the interface offerred to the course coordinator, lists
  195:  official sections and provides a checkbox to use to
  196:  select enrollment in the LON-CAPA course from each official section.  
  197: 
  198:  get_sections takes two arguments - (a) the institutional coursecode
  199:  (in the MSU case this is a concatenation of semester code, department
  200:  and course number), and (b) the LON-CAPA domain that contains the course. 
  201:  
  202:  If there is no access to official course sections at your institution,
  203:  then an empty array is returned, and the Automated Enrollment Manager
  204:  interface will allow the course coordinator to enter section numbers

  219: =item new_course()
  220: 
  221:  This is called by loncreatecourse.pm and 
  222:  lonpopulate.pm to record that fact that a new course section
  223:  has been added to LON-CAPA that requires access to institutional data
  224:  At MSU, this is required, as institutional classlists can only made
  225:  available to faculty who are officially assigned to a course.
  226:  
  227:  The new_course subroutine is used to check that the course owner
  228:  of the LON-CAPA course is permitted to access the institutional
  229:  classlist for any course sections and crosslisted classes that
  230:  the course coordinator wishes to have affiliated with the course.
  231:  
  232:  If access is permitted, then 'ok' is returned.
  233:  The course section or crosslisted course will only be added to the list of
  234:  affiliates if 'ok' is returned.
  235: 
  236:  new_course takes three arguments -
  237:  (a) the institutional courseID (in the MSU case this is a concatenation of 
  238:  semester code, department code, course number, and section number
  239:  e.g., fs03nop590001).
  240:  (b) the course owner. This is the LON-CAPA username and domain of the course 
  241:  coordinator assigned to the course when it is first created, in the form
  242:  username:domain
  243:  (c) the LON-CAPA domain that contains the course

  255: =item validate_courseID()
  256: 
  257:  This is called whenever a new course section or crosslisted course
  258:  is being affiliated with a LON-CAPA course (i.e., by loncreatecourse.pm
  259:  and the Automated Enrollment Manager in lonpopulate.pm).
  260:  A check is made that the courseID that the course coordinator wishes
  261:  to affiliate with the course is valid according to the institutional
  262:  schedule of official classes 
  263: 
  264:  A valid courseID is confirmed by returning 'ok'
  265: 
  266:  validate_courseID takes two arguments -
  267:  (a) the institutional courseID (in the MSU case this is a concatenation of
  268:  semester code, department code, course number, and section number
  269:  e.g., fs03nop590001).

  281: 
  282: =item validate_instcode()
  283: 
  284: This is called when a request is being made for an official course.
  285: A check is made that the institutional code for which a course is
  286: is being requested is valid according to the institutional
  287: schedule of official classes.
  288: 
  289: If the username of the course owner is provided, a more restrictive
  290: test is used, namely that the requestor is listed as instructor of
  291: record for the course in the institution's course schedule/database.
  292: 
  293: validate_instcode takes three arguments -
  294:  (a) the LON-CAPA domain that will contain the course
  295:  (b) the institutional code (in the MSU case this is a concatenation of
  296:  semester code, department code, and course number, e.g., fs03nop590.
  297:  (c) an optional institutional username for the course owner.
  298: 
  299: An array is returned containing (a) the result of the check for a valid 
  300: instcode, and (b) an (optional) course description.   
  301: A valid instcode is confirmed by returning 'valid'.
  302: If no course description is available, '' should be set as
  303: the value of the second item in the returned array.

  313: 
  314: =pod
  315: 
  316: =item validate_crsreq()
  317: 
  318: This is used to check whether a course request should be processed
  319: automatically, or held in a queue pending administrative action at
  320: the institution.
  321: 
  322: Course requests will trigger this check if the process type has been set 
  323: to 'validate' for the course type (official, unofficial or community) and
  324: the requestor's affiliation.  Whether "validate" is an available option
  325: in the Domain Configuration menu is controlled by auto_courserequest_checks(). 
  326: One scenario is where the request is for an official course, in which case
  327: a check could be made that the requestor is listed as instructor of 
  328: record for the course in the institution's course schedule/database.
  329: 
  330: Other scenarios are possible, and the routine can be customized according
  331: to whatever rules a domain wishes to implement to run validations against
  332: given the data passed in to the routine.
  333: 
  334: validate_crsreq takes six arguments -
  335:  (a) the LON-CAPA domain that will contain the course.
  336:  (b) the username:domain for the course owner.
  337:  (c) the course type (official, unofficial or community)
  338:  (d) a comma-separated list of institutional affiliations of 
  339:      the course owner.
  340:  (e) the institutional code (in the MSU case this is a concatenation of
  341:  semester code, department code, and course number, e.g., fs03nop590.
  342:  (f) a comma-separated list of institutional sections included in
  343:      the course request (only applicable to official courses).
  344: 
  345: A valid courserequest is confirmed by returning 'process'.
  346: The following can be returned: process, rejected, pending, approval or error (with error condition - no :), followed by a : and then an optional message. 
  347: 
  348: (a) process  - the requestor is the recorded instructor - create the course
  349: (b) rejected - the requestor should never be requesting this course, reject the
  350:     request permanently
  351: (c) pending - the requestor is not the recorded instructor, but could
  352:     become so after administrative action at the institution. Put the
  353:     request in a queue and check localenroll:validate_instcode()
  354:     periodically until the status changes to "valid".
  355: (d) approval - the request will be held pending review by a Domain Coordinator.
  356: (e) error (followed by the error condition).

  365: 
  366: =pod 
  367: 
  368: =item crsreq_checks()
  369: 
  370: This is used to determine whether the "validate" option should appear in the
  371: possible choices for course request processing in the Domain Configuration 
  372: menu for Course Requests. Ultimately it is called by domainprefs.pm (via: 
  373: lonnet -> lond -> localenroll.pm) The domain configuration menu includes 
  374: a table where columns are course type (official, unofficial or community) 
  375: and rows are institutional affiliations (e.g., Faculty, Staff, Student etc.).
  376: 
  377: crsreq_checks() takes three arguments: $dom, $reqtyes, $validations.
  378: $dom - the domain for which validation options are needed.
  379: $reqtypes - ref to an ARRAY of course types (i.e., official, unofficial and community.
  380: $validations - ref to a hash of a hash which will determine whether "validate"
  381: will be one of the possible choices for each course type (outer hash key),
  382: and institutional type (inner hash key).
  383: 
  384: For example to allow validate to be a choice for official classes for Faculty,
  385: req_checks would include:
  386: 
  387: $validations{'official'}{'Faculty'} = 1;
  388: 
  389: This routine is closely tied to validate_crsreq(). "Validate" should not be
  390: a possible choice in the domain configuration menu for a particular course
  391: type/institutional affiliation, unless a corresponding validation code has
  392: been implemented in validate_crsreq().
  393: 
  394: For example at MSU, official courses requested by Faculty will be validated
  395: against the official schedule of classes to check that the requestor is one
  396: of the instructors of record for the course.  In this case validate_crsreq()
  397: includes a call to validate_instcode().

  418: =item create_password()
  419: 
  420:  This is called when the authentication method set for the automated 
  421:  enrollment process when enrolling new users in the domain is "localauth".
  422:  This could be signalled for the specific user by the value of localauth
  423:  for the <authtype> tag from the classlist.xml files, or if this is blank,
  424:  the default authtype, set by the domain coordinator when creating the course
  425:  with loncreatecourse.pm.
  426:   
  427:  create_password takes three arguments -
  428:  (a) $authparam - the value of <autharg> from the classlist.xml files,
  429:  or if this blank, the default autharg, set by the domain coordinator when 
  430:  creating the course with loncreatecourse.pm
  431:  (b) $dom - the domain of the new user.
  432:  (c) $username - the username of the new user (currently not actually used)
  433: 
  434:  Four values are returned:
  435:  (a) the value of $authparam - which might have been changed
  436:  (b) a flag to indicate whether a password had been created
  437:  0 means no password created
  438:  1 means password created.  In this case the calling module - Enrollment.pm
  439:  will send the LON-CAPA username and password to the new user's e-mail
  440:  (if one was provided), or to the course owner (if one was not provided and
  441:  the new user was created by the automated process), or to the active
  442:  course coordinator (if the new user was created using the 'update roster
