Managing Virtual Organisations (VOs) in Check-in

This page contains information about using Check-in for managing your Virtual Organisation (VO).

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 following link: https://wiki.egi.eu/wiki/PROC14_VO_Registration#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 My VO-NAME Population (for example, My vo.example.org Population)

    My VO population menu

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

    My VO population

Accepting new VO members

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.

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.

The VO enrollment URL can be found through the 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

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 My <VO-NAME> Population (for example, My vo.example.org Population)

    My 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.

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:
    • A COU admins group member can manage COU members:
    • Approve or decline membership petitions
  • Manage members’ roles
    • A COU admins group owner has permission to add and remove members to and from the group, i.e. manage the list of CO Persons who can manage the COU members

A COU admins group owner can manage the admins group member as follows:

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

  2. To view the available groups expand the Groups drop down list and click All Groups

    Groups drop down

    Expand the Filter section and find the COU admin group you are interested in. For the case of the service-integration COU with type the string service-integration in the text box with the placeholder Name.Then we click on Filter button

    Expand groups

  3. Locate Admins group click on Edit action

    Groups actions

Assign COU member admin role

From the steps defined above:

  1. Follow Manage Group Memberships link

    Manage Group Memberships link

  2. Filter out the CO Person you need to apply for the admin role. Use Given, Family Name, Email, Identifier or a combination of the former.

Remove COU admin role

From the steps defined above:

  1. Under Group Members tab, click on Delete action for the CO Person that needs to be removed from Admins group

    Group members tab

VO membership API

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 ePUID
  • 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 ePUID, the name of the VO (e.g. vo.access.egi.eu 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"
    

    ad.json:

    {
      "RequestType": "VoMembers",
      "Version": "1.0",
      "VoMembers": [
        {
          "Version": "1.0",
          "VoId": "vo.access.egi.eu",
          "Person": {
            "Type": "CO",
            "Id": "01234567890123456789@egi.eu"
          },
          "Status": "Active",
          "ValidFrom": "2017-05-21",
          "ValidThrough": "2017-06-21"
        }
      ]
    }
    
  2. Retrieving the VO membership information for a given EGI Check-in ePUID:

    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.access.egi.eu",
        "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
