Authentication and Authorization module

Requirements list

Authentication

• Forms of Authentication:
  • Database (user-pass) (must)
  • OpenID (could)
  • IP-based (could)
  • LDAP-based + specific flavors like RUG and UMCG login (should)
• Registration of users includes email verification (must)
• Users should be able to login and logout (must)
• Users should be able to change their passwords (must)

Authorization

• Resources are tables, rows, columns, query-sets (e.g. only the Lengths in rows where Length > 1.80m), files (for pipelines)
• Subjects are users, groups, public users (unauthenticated) and exactly one administrator
• Permissions include read, write (also implies delete), execute (for pipelines) and ownership
• Modifying (insert, delete, alter) a column is not supported.
• Modifying a row needs write rights on the row.
• Resources must have exactly one owner; this can either be a user (must) or a group (should). The latter option is not preferable for us and needs to be set explicitly by the administrator.
• Permissions are provided for resources x subjects. (must)
• The administrator has all permissions excluding ownership on all resources. (must)
• Authenticated users can request permissions for resources. Requests are sent to the user or group with ownership rights of the resource. (must)
• Groups can be created by users who have write rights on the MolgenisGroup? table. The administrator is the owner of the MolgenisGroup? table and can delegate rights to other users. (must)
• In case of an UpdateDatabase? all permissions are reset (except for administrator).
• The public user has by default no reading permissions on any resource, unless explicitly set by the administrator. (should)
• Administrator can pass on permissions from parent tables to child tables and between xref-linked tables with a toggle button. (should)

Example

Table: ObservedValue

	read	write	execute	ownership
User1	x	x	x	x
User2	x		x	-(?)
Group1		x		-(?)
Group2	x	x	x	-(?)
...
Admin	x	x	x	-

Needs of the PhenoFlow module (lifelines, bbmri, gids2.0, col7a1, xgap)

PhenoFlow is the user interface for searching, browsing and extracting phenotype data from the Pheno model. This browsing module will be central in most of our applications.

The systems (that will be) using this module are

• LifeLines (datawarehouse)
• BBMRI-NL (biobank catalog) and
• gids (2.0).
• COL7A1 Phenotype/Patient? browser (here one gene == one investigation)
• XGAP data browser

Requirements:

• Users need to be able to login
• All registered users have edit permissions to create new investigations
• All existing investigations can only be listed (names) but no other values
• All investigations are owned by one or more persons
• If not yet owned, users can request to become manager of an investigation.
• Otherwise users can request read access to the investigation
• Users can create groups of themselves (except for lifelines)
• Users can share an investigation and all its components to [public, groups, whitelists of users) for viewing
• The sharing rules can be read or write (so that means they can transfer management of an investigation)
• All InvestigationElement? inherit the sharing rules set on an investigation (hence, if the investigation is public so are all its elements)
• Individual investigation elements, and the dataelements that refer to them can have different permissions (lifelines)

Issues:

• What about data that is not an Investigation/InvestigationElement??

See www.myexperiment.org for some inspiration on how this 'sharing' model can work. See www.myexperiment.org for some inspiration on how this 'sharing' model can work.

Needs of the xQTL Workbench

Requirements:

General:

• All data input/output needs to be closed / secured
• Unregistered users can still view public datasets

User:

• Users need to be able to register (as users)
• Confirmation email to the registrar
• Users need to be able to register/confirm their email
• Users need to be able to login
• When loged in users are able to view public datasets and their own datasets

Admin:

• Administrators need to be able to: Authenticate users, Ban users, Delete unused accounts
• Administrators are not able to register, view all,execute all
• Users cannot be promoted to admin, admins cannot be demoted to users
• Admins donnot register, but are 'hardcoded' into the application
