Managing a Virtual Organisation

Managing a Virtual Organisation (VO) in Check-in

This page contains information about using Check-in for managing your Virtual Organisation (VO). For joining a VO please look at Joining Virtual Organisation.

Background

In simple terms a Virtual Organisation (VO) is just a group of users. In EGI VOs are created to group researchers who aim to share resources across the EGI Federation to achieve a common goal as part of a scientific collaboration. For a more formal definition of VO please look at the EGI Glossary.

You can browse existing VOs in the EGI Operations Portal. For each VO you can click on the Details link to get more information. You can join an existing VO either using the enrollment URL or emailing VO managers.

If you are interested in creating your own VO, please see instructions in the section below.

VO management

VOs in Check-in are represented as Collaborative Organisation Units (COUs). A COU is more than just a group. It is the concept of groups combined with membership management and advanced enrolment workflows. COUs can also be organised in a hierarchical structure for creating groups or subgroups within a VO.

It is assumed that VO managers and members have already registered their EGI Check-in account (A step-by-step guide is provided in this link.

Registering your VO

Any person who can authenticate to the Operations Portal using their EGI Check-in account can register a new VO.

The person initiating the registration is called the VO manager. After the VO is set up and operational, the VO manager is the person who is primarily responsible for the operation of the VO and for providing sufficient information about VO activities for EGI and for VO members (to both people and sites).

A step-by-step guide for the VO registration process is provided in the procedure PROC14 VO Registration.

Viewing VO members

  1. Login to Check-in registry using any of the login credentials already linked to your EGI account.

  2. To view the existing members, expand the People drop down menu and click on VO-NAME Population (for example, vo.example.org Population)

    VO population menu

  3. Then you are able to see all the VO members.

    VO population

VO enrollment URLs

Vo enrollments URLs are essential for someone who wants to enroll to a VO.

Users can request membership in your VO by following the VO enrollment URL. The enrollment URL has the following form:

https://aai.egi.eu/registry/co_petitions/start/coef:## where ## is the unique numeric identifier for the enrollment flow of your VO.

The VO Manager can insert this URL in an invitation email and send it directly to the users who want to join the VO. Also, it can be used in any registration web page as an href of a button or image etc.

The VO enrollment URL can be found both at the Operations Portal and EGI Check-in Registry. At the Operations Portal VO List, by quickly searching for the VO name and clicking on the Details.

At EGI Check-in Registry:

  1. Login to Check-in registry using any of the login credentials already linked to your EGI account.

  2. Expand the People drop down menu and click Enroll.

    COmanage-people-enroll

  3. Copy the Begin link of the Enrollment flow of the VO you want the user to join and send it to the user

    Join example

  4. Once the user submits the VO membership request, the Role Attributes section of their profile page will include the new VO membership role in Pending Approval status

    Pending Approval

  5. Once the VO manager accepts the new member, the Role Attributes section of the user’s profile page will include the VO membership role in Active status

    Member role active

Reviewing VO membership requests

Once a user submits a VO membership petition, all VO managers are notified with an email containing a link to the petition. Any of the VO managers can then review the petition and either approve or deny the request.

When a user requests membership to a VO, all VO managers will receive an email, containing the petition URL.

Except from email, they will receive a notification on their COmanage profile. At the top right corner clicking the bell icon someone can see all the notifications.

COmanage-notification-icon

Clicking a notification message, you can find among others, the petition URL inside the Notification Email Body field.

COmanage-notification-message

Clicking the petition URL either at mail you received either at the notification message, you can review the request.

You can accept or deny the membership, and also provide a justification at the textarea, below the two buttons. This field is optional. In case is filled, it will also be sent to the user that made the request.

COmanage-petition-approve-deny

In the petition view you can also view user’s assurance per linked identity under Assurance section. More information about identity assurance can be found here.

COmanage-petition-assurance

The complete user profile can be found by clicking the enrollee name under Attached Identities (in Petition View).

COmanage-petition-attached-identities

At user profile you can find also information about Organisation Identities. An Organisation Identity, among others, includes information about Certificates and Assurances.

COmanage-user-org-identities

Managing VO groups

VO groups can only be created by Check-in platform administrators. Please contact checkin-support <AT> mailman.egi.eu indicating the following information for every (sub)group that you need to add/remove to/from your VO:

  • VO name
  • Group name
  • Group description
  • Optional, Group manager(s), i.e. the Check-in identifiers (in the form of "xxxxxxx@egi.eu") of one or more users responsible for managing the VO group members. Group managers can also appoint other users as (sub)group managers. The manager(s) of the VO (or any parent group) are implicitly managers of the group. You can provide additional Check-in user identifiers to extend the list of group managers.
  • Optional, Parent VO group name (in the case of a hierarchical group, e.g. <VO> –> <PARENT_GROUP> –> <GROUP>)

Known limitation: Group names must be unique so the names you suggest may need to be adjusted by the Check-in administrators to guarantee their uniqueness.

Adding members to VO groups

  1. Login to Check-in registry using any of the login credentials already linked to your EGI account.

  2. Then expand the People drop down menu and click <VO-NAME> Population (for example, vo.example.org Population)

    VO population menu

  3. Find the user you want to add to the VO Group and click Edit.

    Edit VO Population

  4. Click Add at the Role Attributes section of the user profile

    Add role

  5. Fill in the fields in the form and click Add. The user now is a member of the new VO group. For more information about Affiliation and Role fields you can see below at section Managing Affiliation and Role of VO Member

    Add role in group

Removing members

From the VO members list (see Viewing VO members above):

  1. Click Edit on the person that is going to be removed.

    VO population to edit

  2. Under Role Attributes click Delete on the right of the COU entry of interest (for example, vo.example.com). On success the selected row will be removed. In this example we removed the vo.geoss.eu that we previously added.

    VO population removed user

Managing Affiliation and Role of VO Member

User’s Affiliation to a VO, as defined in RFC4512, has eight permissible values. These are faculty, student, staff, alum, member, affiliate, employee, library-walk-in. EGI Check-in assigns to all user’s the affiliation Member by default, during the VO(COU) enrollment process. This value is immutable for the user but editable for the VO administrator. As a result, if there is a change of status the administrator can always step in and change it appropriately. Additionally, the user’s Role in a VO is the EGI User Community Title column, in Co Person Role’s View. This column can be either a custom text value; or a value chosen from a drop down list. The drop down list administration is an EGI Check-in CO administrator task and can not be managed by any VO admin.

Update User’s VO affiliation

  1. Navigate to Co Person Role view CO person role view

  2. Choose Affiliation from drop down list VO affiliation

Update User’s VO Role

  1. Navigate to Co Person Role view CO person role view

  2. Choose Role from drop down list, if available, or add custom text if no list is present. Role title

Subsequently, EGI Check-in uses the CO Person’s group membership and role information in order to construct the eduPersonEntitlement values, in short entitlements. These URN-formatted attributes can be used for representing group membership, as well as to indicate rights to resources. According to the AARC-G002 specification, a user that is a member of the VO vo.example.org, and has the role supervisor, obtains the following entitlements:

  • urn:mace:egi.eu:group:vo.example.org:role=member#aai.egi.eu

  • urn:mace:egi.eu:group:vo.example.org:role=supervisor#aai.egi.eu

Managing COU Admin members

COU Admin Groups are used to determine COU Administrators. Admin Groups are automatically created when a COU is created. The default name for COU admin groups is

CO:COU:<COU_Name>:admins

For example CO:COU:vo.example.org:admins

  • A CO Person can be a member, an owner, both, or neither. Specifically:
    • COU Admin Group members can manage COU members
    • Approve or decline membership petitions

A CO Person is added to a COU Admin Group if the following requirements are met:

  1. CO Person is declared as VO administrator in the VO’s ID Card, under the Operations Portal

  2. A request is made to the Check-in Support Unit via a EGI Helpdesk ticket.

Expiration Policy

VO membership expires within a given time, typically a year after the VO member joins the VO. VO members receive a notification from EGI Check-in Notifications with the subject “vo.example.org membership will expire soon” warning them that their membership will expire four weeks before expiration. The notification email is sent on a weekly basis and includes all the instructions needed by VO members in order to reapply for a membership. If the VO member does not take any action to renew their membership, a final notification email is sent when the VO membership expires. Please note that a user with expired membership is not eligible for VO membership entitlements and as a result the user will not have access to VO resources relying on these entitlements.

VO API

API v2

Check-in provides a REST API that allows clients to:

  • manage membership information only for the VOs they are authoritative for
  • get VO group information only for the VOs they are authoritative for

Membership Features:

  • Members of the VO are identified via their EGI Check-in Community User Identifier (CUID)
  • Membership can be limited to a specified period
  • All REFEDS membership affiliations are supported
  • Role titles are supported
  • Different membership status values are supported, namely Active, Expired, Deleted, Suspended
  • Check-in automatically changes the membership status from Active to Expired beyond the validity period

Connection Parameters

The API username and API password will be assigned by the EGI Check-in team when you request REST API access. In order to obtain REST API credentials you need to email your request to EGI Check-in Support with Subject Request REST API access for <vo_name> VO. Make sure you indicate the instance of EGI Check-in (production, demo or development) hosting the VO you request access to. Only VO managers can request REST API credentials for a given VO.

Authentication

The REST client is authenticated via username/password credentials transmitted over HTTPS using the Basic Authentication scheme. More sophisticated authentication mechanisms, such as OpenID Connect/OAuth 2.0 access tokens, may be supported in the future.

API v1 (DEPRECATED)

Check-in provides a REST API that allows clients to manage membership information only for the VOs they are authoritative for.

Features:

  • Members of the VO are identified via their EGI Check-in Community User Identifier (CUID)
  • Membership can be limited to a specified period
  • Different membership status values are supported, namely Active, Expired, Deleted
  • Check-in automatically changes the membership status from Active to Expired beyond the validity period

Authentication

The REST client is authenticated via username/password credentials transmitted over HTTPS using the Basic Authentication scheme. More sophisticated authentication mechanisms, such as OpenID Connect/OAuth 2.0 access tokens, may be supported in the future.

Methods

  1. Adding a user to a VO requires specifying the user’s EGI Check-in CUID, the name of the VO (e.g. vo.example.org in the case of LToS), the status (Active) and the valid from/through dates. All these parameters are mandatory. Here is an example using curl (see example add.json file below):

    $ curl -vX POST https://aai.egi.eu/api/v1/VoMembers \
           --user "example-client":"veryverysecret" \
           --data @add.json \
           --header "Content-Type: application/json"

          "ValidFrom": "2017-05-21",
          "ValidThrough": "2017-06-21"
        }
      ]
    }
    
  2. Retrieving the VO membership information for a given EGI Check-in CUID:

    $ curl -vX GET https://aai.egi.eu/api/v1/VoMembers/01234567890123456789@egi.eu \
           --user "example-client":"veryverysecret"
    

    output:

    [
      {
        "id": 85,
        "epuid": "01234567890123456789@egi.eu",
        "vo_id": "vo.example.org",
        "valid_from": "2017-05-20T22:00:00.000Z",
        "valid_through": "2017-06-21T22:00:00.000Z",
        "status": "Active"
      }
    ]
    

    Beyond the valid_through date, the status will be automatically changed to Expired. So, when querying for VO membership information, it’s important to check that the status is actually set to Active for each of the identified VOs (see the vo_id attribute)

  3. Updating existing VO membership record:

    $ curl -vX PUT https://aai.egi.eu/api/v1/VoMembers \
           --user "example-client":"veryverysecret"  \
           --data @update.json \
           --header "Content-Type: application/json"
    

    The request body is the same as the one used for adding new members but update requires using PUT instead of POST.

  4. Removing VO member:

Same as the update but requires setting the membership status to Deleted

LDAP

EGI Check-in provides read access to the members of the VO(s) through the Lightweight Directory Access Protocol (LDAP).

There are two entity types in the LDAP:

  • People: Users of EGI Check-in, expressed as inetOrgPerson (with additional attributes/schemas).

  • Groups of collaboration members, expressed as groupOfMembers (with additional attributes/schema).

Connection Parameters

Bind DN: <provided by EGI Check-in support>

The Bind DN and Bind Password will be assigned by the EGI Check-in team when you request LDAP access. In order to obtain LDAP credentials you need to email your request to EGI Check-in Support with Subject Request LDAP access for <vo_name> VO. Make sure you indicate the instance of EGI Check-in (production, demo or development) hosting the VO you request access to. Only VO managers can request LDAP credentials for a given VO.
