Description

This part of the SDS Modernization (SDSM) document provides details on the kinds of SDS users and their privileges.

RETURN

Kinds of Users

A user is an individual human that interacts with SDS.

An account is an entity that represents a single user' in SDS and is the means by which a user interacts with the app while they are authenticated to it.

SDS is fundamentally a private system and has no significant functionality available to any user while the latter is not authenticated or logged in to the app.

The most significant SDS screens that a non-authenticated user can interact with are the Public Home app landing screen welcoming them to the app, and the Login screen for authenticating to their account.

Note that any references in this SDSM document to a user, except when explicitly qualified otherwise, specifically means a non-anonymous user who has an account and is currently authenticated to it.

An internal user is a user that currently works for or is a student at SMUS; they have a Microsoft Active Directory account with the school which is the source of truth for their identity that they use to authenticate with both SDS accounts and many other school systems such as PCs and SMUS email accounts.

(Note that some individuals who work for SMUS, typically by way of companies contracted to the school, do not have school Microsoft Active Directory accounts because they don't need school email accounts, and so they also are not SDS users.)

An external user is a user that currently neither works for nor is a student at SMUS; they do not have a Microsoft Active Directory account with the school, and the source of truth for their identity that they use to authenticate with SDS accounts (and nothing else) is a different exclusive school LDAP server.

Parents of current students are typically external users, except for those such parents who are instead internal users for other reasons, such as because they also currently work for the school.

Alumni of the school are a gray area that might still have Microsoft Active Directory school accounts in order to support maintaining a school email address, but they are not SDS users, unless for other reasons, such as because they also currently work for the school or are parents of current students.

Note that any references in this SDSM document to school LDAP server typically refer to a Microsoft Active Directory server, as LDAP is the protocol SDS uses to talk with it.

RETURN

Roles and Privileges of Users

Each SDS user account is granted a set of privileges which determine what app functionality that user may employ. A typical privilege corresponds to a single app screen and confers usage of that screen to that user, though other kinds of privileges may also exist.

A user is typically granted a privilege indirectly by way of that user being assigned membership to a user group that is in turn granted that privilege. A user less often is granted a privilege directly.

A school LDAP server is the source of truth for what user groups exist, expressed as LDAP groups, and for what user accounts are members of those groups. There are currently 187 such LDAP groups defined.

The SDS database table group_permissions is the source of truth for what LDAP groups have been granted privileges to access specific SDS Gavintech screens, and the table group_pages does that for specific SDS Laravel screens.

Currently, 29 of the 187 LDAP groups have been granted privileges for 1 or more SDS Gavintech screens each (the rest zero), out of which 6 have been granted exactly 1 screen each, 9 have been granted between 2 and 9 screens each, and 11 have been granted between 11 and 67 each, and 3 have been granted 100 or more each. (The database also has grants for 2 currently non-existent LDAP groups in addition to for the existing 29.)

The SDS database table person_permissions is the source of truth for what user accounts have individually been granted privileges to access specific SDS Gavintech screens, and no corresponding mechanism is yet implemented for SDS Laravel screens.

Each SDS user account is also defined in the SDS database to possess one or more roles, each of which is explicitly and specifically recognized in the SDS application logic, and affects how that user account is treated, both with respect to what that account's user is allowed to do in the app, and with respect to what kind of records and activities are associated with that user in the database. This logic may be arbitrarily complex and is distinct from the effect of granting generic yes/no screen access privileges.

Examples of those explicit roles are:

  • The user currently is a student at the school.
  • The user is a parent/guardian of a current student.
  • The user currently works as a teacher for the school.
  • The user currently works as administrative staff for the school.

The SDS screens are broadly divided into 3 mutually exclusive screen groups, for students, parents, and teachers/staff respectively.

Current students see this SDS main menu:

  • Student Menu

Parents of current students see these SDS main menus:

  • Academics
  • Administration
  • Forms
  • School Information
  • Tuition & Payment

Teachers and administrative staff see these SDS main menus:

  • Admin Menu
  • Staff Menu

In addition, teachers with their own courses see this SDS main menu:

  • My Courses

A user who is both a teacher/staff and a parent may see nearly all main menus.

As a special case, a user who works as a developer/debugger of SDS for the school might see all of the menus even if a normal user wouldn't.
