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 |
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
- ) who has not been added to a role in the 'SU Realm' which has the 'Can SU' security function, or
- ) who has been added to a role in the 'SU Realm' which does not have the 'Can SU' security function
SuperUser = any user that has a 'magical' name or ability to edit the admin home site (i.e., a SmartSite admin user.)
What is expected:

- 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 - Validate SuperUser cannot SU another SuperUser
Login as admin and select the test site that contains the SU Tool.
Type in the name of another SuperUser and select 'become user'.
Expected result: 'unauthorized' - SuperUsers cannot su a SuperUser account
Test 4 - Validate Standard User cannot SU another Standard User
Login as a Standard User and select the test site that contains the SU Tool.
Type in the name of another Standard User and select 'become user'.
