1.2 raeburn 1: \label{Institutional_Integration_Identity_Management}
1.1 raeburn 2: Two subroutines exist in localenroll.pm to provide a connection between
3: institutional directory data (e.g., user information from LDAP) and
4: LON-CAPA. The first is \emph{get\_userinfo()} which can operate in
5: two modes.: (a) it can be used to provide first name, last name, e-mail
6: address, student/employee ID etc., for a specified username, e.g.,
7: for a new user being created in LON-CAPA, and (b) it can be used to
8: retrieve user information for multiple users from an institutional
9: directory searches when (for example) a course coordinator is adding
10: a new user directly to a course. At MSU the routine which actually
11: queries institutional data sources is itself called by \emph{get\_userinfo()}.
12: This was done so that the same underlying routine can also be used
13: by the second of the two subroutines: \emph{allusers\_info()} which
14: is called by Autoupdate.pl (a script which can be run periodically
15: to reconcile user information in LON-CAPA with institutional directory
16: data for all users).

20: \textbf{\large get\_userinfo}{\large \par}
21:
22: Four required arguments and additional optional arguments
23:
24: Two modes of operation:
25:
26: \begin{enumerate}
27: \item Retrieves institutional data for a single user either by username,
28: if \$uname is included as second argument,
29:
30:
31: or by ID if \$id is included as a third argument. Either second or
32: third arguments must be provided; seventh, eighth and ninth args will
33: be undefined.
34:
35: \item Retrieves institutional user data from search of an institutional
36: directory based on a search. seventh and eighth args are required;
37: ninth is optional. second and third will be undefined.
38: \end{enumerate}
39: Arguments:
40:
41: \begin{enumerate}
42: \item \$dom - domain
43: \item \$uname - username of user
44: \item \$id - student/faculty ID of user
45: \item \$instusers - reference to hash which will contain info for user as
46: key = value; keys will be one or all of: lastname, firstname, middlename,
47: generation, id, inststatus - institutional status (e.g., faculty,staff,student).
48:
49:
50: Values are all scalars except inststatus, which is an array.
51:
52: \item \$instids - reference to hash which will contain ID numbers - keys
53: will be unique IDs (student or faculty/staff ID)
54:
55:
56: values will be either: scalar (username) or an array if a single ID
57: matches multiple usernames.
58:
59: \item \$types - optional reference to array which contains institutional
60: types to check.
61: \item \$srchby - optional if \$uname or \$id defined, otherwise required.
62:
63:
64: Allowed values include: 1. lastfirst, 2. last, 3. uname corresponding
65: to searches by 1. lastname,firstname; 2. lastname; 3. username
66:
67: \item \$srchterm - optional if \$uname or \$id defined, otherwise required
68: - String to search for.
69: \item \$srchtype - optional. Allowed values: contains, begins (defaults
70: to exact match otherwise).
71: \end{enumerate}
72: Returns 'ok' if no error occurred. Side effects - populates the \$instusers
73: and \$instids refs to hashes with information for specified username,
74: or specified id, if fifth argument provided, from all available, or
75: specified (e.g., faculty only) institutional datafeeds, if sixth argument
76: provided.
77:
78: At MSU six separate MS-SQL database tables are queried, with each
1.3 raeburn 79: table corresponding to a specific institutional type. A routine is
1.1 raeburn 80: called to connect to the database. and the actual queries are handled
81: by a separate routine - \emph{query\_user\_tables()}.

496: student/employee IDs available from MSU's LDAP service. The LDAP search

1.3 raeburn 498: official usernames from MSU), but are not currently affiliated with
1.1 raeburn 499: any of the institutional user types, so are absent from the six SQL
