SU Tool - Test Plan

JIRA: SAK-131: Add Role based SU security

This request to add Role-based SU security encompasses two parts:

a role-based limitation and specification of which roles may use SuperUser (SU) access and what the limitations of SU access are based on the original user's role, and
allows the portal to recoginze that the user is in an SU role and provide a UI mechanism (link or button) for the user to leave SU and return to their own role without having to log out and log in again.

The story details of these separate tasks are listed as:

SAK-354: Add Role based SU security
SU tool uses Security(Service).isSuperUser() to determine who can SU. This should be modified to use agent,/function/target ....

IT Express - can su - students
IT Express - can su - faculty
IT Express - cannot su - admin

SAK-367 - CharonPortal Tracking of assumed Id's with 'Return to...'
part two of two
2) CharonPortal patch: - assumed identities tracked with 'Return to <Eid>' link next to Logout link
create special url ('/realuser') that the portal will use to reload any existing previous usage session

Test for sub-story SAK-354: add realm based security to SuTool

This test plan covers the sub-story SAK-354: add realm based security to SuTool ONLY

Description:
This modification to the SU Tool is intended to allow users who are not SuperUser to SU other users. On Start up, the tool looks for or creates a security realm (reference: realms tool).... by default the realms name is '!su.can_su_realm' but it can be modified by editing the tool registration file.

Administrators should add roles to this realm which have the appropriate security function (or permission). This function name is 'su.can_su' by default (but can be changed by an administrator by editing the tool registration file).

The template permission matrix with an example of source, target, and results:

source	function	target	result
user A	can SU	user B	true/false

Definitions: Types of users

Priv User = users that are added to a role in the 'SU Realm' which has the 'Can SU' security function
Standard User =

) any user that is not SuperUser and has not been added to a role in the 'SU Realm' which has the 'Can SU' security function, or
) any user that is not SuperUser and has been added to a role in the 'SU Realm' which does not have the 'Can SU' security functionSuperUser = any user that has a 'magical' name or ability to edit the admin home site.

What is expected:

test	source	function	target	Test #
SuperUser	can SU	SuperUser	false	test 3
SuperUser	can SU	Priv User	true
SuperUser	can SU	Standard User	true
Standard User	can SU	SuperUser	false	test 5
Standard User	can SU	Priv User	false
Standard User	can SU	Stardard User	false	test 4
Priv User	can SU	SuperUser	false	test 6a
Priv User	can SU	Standard User	true	test 6b
Priv User	can SU	Priv User	true

Preparation

a test site with SU Tool installed (see #SU Tool Setup to set up a course)
at least two non SuperUser accounts in the test site
at least two SuperUser accounts

Test Series

Assumption

Default realm name and default security function name in tool reg file

Test 1 - Validate that SU Tool can be created upon access by SuperUser

Login as admin, access the Realms tool, and delete the the realm entitled '!su.can_su_realm'.
Select the test site that contains the SU Tool.
Type the name of any non-admin or admin user and select 'Become User' button (the latter case will fail the su, but should achieve the desired results for this test.)
If necessary, log out and re-login as an admin user.
Return to Realms tool and search for the above realm name.

Expected result: '!su.can_su_realm' will be created if missing the first time the tool is opened by a SuperUser.

Test 2 - Validate that SU Tool can be created upon access by Standard User

Login as admin, access the Realms tool, and delete the realm entitled '!su.can_su_realm'.
Log out and re-login as a non-admin user in the test site with the SU Tool.
Log out and re-login as admin.
Return to Realms tool and search for the above realm name.

Expected result: '!su.can_su_realm' will be created if missing the first time the tool is opened by a Standard User.

Test 3

Login as admin and select the tool page that contains the SU Tool
type in the name of another SuperAccount and select 'become user'

Expected result: 'unauthorized' - SuperUsers cannot su a SuperUser account

Test 4

Login as a standard user and select the tool page that contains the SU Tool
type in the name of another standard user and select 'become user'

Expected result: 'unauthorized' - Standard users cannot su another standard user account with out the correct permissions

Test 5

Login as a standard user and select the tool page that contains the SU Tool
type in the name of SuperAccount and select 'become user'

Expected result: 'unauthorized' - Standard users cannot su a SuperUser account.

Test 6

prep for 6-a and 6b

1. Login as admin and access the realms tool and edit the realm entitled '!su.can_su_realm'
2. Add a role (example 'Can SU')

4. click on 'add a grant'
5. type in the name of a standard user in the test site.

Logout and re-login as the username given in #3
Select the tool page that contains the SU Tool

6-a

select tool reset button
type in the name of SuperUser and select 'become user'

Expected result: 'unauthorized' - Privileged users cannot su a SuperUser account.

6-b
