Delegated Administration of Metadata
The term delegated administration refers to the ability of a site administrator to delegate responsibility for administering SP metadata to another administrator called a delegated administrator. The rationale for delegated administration was discussed in a blog post published early in 2012. The primary motivation for adding this feature to the Federation Manager (FM) is to simplify metadata management for those sites with large numbers of entities in metadata.

As of 13 October 2013, the Google Gateway is a production service! Delegated administrators can now log into the Federation Manager with their Google accounts.
Facts About Delegated Administration
- A site administrator delegates the ability to administer SP metadata to a delegated administrator by providing the
eduPersonPrincipalNameand e-mail address of a prospective delegated administrator.
- A site administrator constrains the privileges of each delegated administrator, that is, the site administrator assigns delegated administrators to manage particular SPs.
- A delegated administrator is able to administer SP metadata only.
- A delegated administrator may create/modify/delete SP entity descriptors.
- A metadata update request submitted by a delegated administrator must be approved by a site administrator.
- The delegated administrative login interface accepts federated credentials only (i.e., InCommon Operations does not issue passwords to delegated administrators).
- The delegated administrator’s IdP must support SAML V2.0 Web Browser SSO (i.e., SAML V1.1 is not supported).
- The delegated administrator’s IdP must release a set of required attributes to the Federation Manager.
- A site administrator for an organization may not function as a delegated administrator for the same organization.
- A delegated administrator for one organization may not function as a delegated administrator for another organization.
- Assigning two delegated administrators to the same entity descriptor can have undesirable side effects since the editing of entity descriptors is not constrained by the software in any way.
- A site administrator can not unconditionally delegate responsibility for administering SP metadata; that is, a site administrator must always approve update requests made by a delegated administrator.
For the Site Administrator
Login to the FM as a site admin
As a site administrator, you have the ability to provision one or more delegated administrators to manage SP metadata. You determine which entity descriptors may be edited by explicitly assigning a delegated administrator to one or more SPs. Any updates submitted by a delegated administrator are bounced back to you for approval, so the risk associated with the delegation of SP metadata is minimal.
If you provisioned one or more delegated administrators prior to November 19, 2012 (when an upgrade to delegated administration occurred), please do the following:
Each delegated administrator assigned as described above should now be able to edit SP metadata.
Preparing Your IdP
Since the delegated administrative login interface accepts federated credentials only, a site administrator must configure the IdP to release the following attributes to the Federation Manager (https://fm.incommon.org/sp):
You can test your IdP by logging into the following test SP: https://service1.internet2.edu/test/
Provisioning a Delegated Administrator
It's easy to provision a delegated administrator. To do so, a site administrator logs into the Federation Manager as usual and clicks the menu item "Delegated Administrators" along the left hand side of the page. After providing
and email address of a prospective delegated administrator, the system sends an email invitation to the given email address (copying all other site administrators as well). The prospective delegated administrator clicks the link in the email to continue with the boarding process.
If the delegated administrator will be using the Google Gateway, the
Once the delegated administrator has successfully logged into the Federation Manager via SAML Web Browser SSO, a local account is provisioned. No local credentials are issued---the delegated
logs in with a federated credential.

Assigning Privileges to a Delegated Administrator
Delegated administrators are assigned to specific SPs. If you don't assign a delegated administrator to an SP, that delegated administrator will only be able to create new SP metadata. Typically, any given SP will have at most one delegated administrator assigned to it (although multiple delegated administrators may be assigned to a single SP if you choose).
If multiple delegated administrators are assigned to a single SP, one delegated administrator may edit and submit metadata without being aware that another delegated administrator has already submitted an update request for the same entity descriptor. For this reason, it is recommended that at most one delegated administrator be assigned to a particular SP.
Approving Updates Made by a Delegated Administrator
Since all updates must be approved by a site administrator, the integrity of metadata is maintained.
Since the site administrator approves all update requests, it is the site administrator who ultimately assumes the responsibility for all metadata submitted (which is the case in the absence of delegated administration as well).
For the Delegated Administrator
As a delegated administrator, you will be able to create new SP metadata and edit existing SP metadata subject to policy. Your privileges have been assigned to you by a site administrator. If you are unable to perform some action, talk to your site administrator. Only a site administrator can assign privileges to a delegated administrator.
Create New SP Metadata
Click the link "Add a New Service Provider" to
SP metadata. Visit
wiki page for tips, recommendations, and requirements regarding the administration of SP metadata.
Any new metadata you create must be approved by your site administrator.
Edit Existing SP Metadata
When you login as a delegated administrator, you will be presented with a list of all SPs owned by the organization. Those SPs you have been given permission to edit will have an "Edit" link next to their entity ID. Click the link to edit the metadata for that SP. If there is no "Edit" link next to the SP you want to edit, talk to your site administrator.
Any metadata updates you submit must be approved by your site administrator.
Unlinking a Certificate
You may notice a link labeled "Unlink from the metadata" next to a certificate reference. This means the certificate was previously uploaded to the system by a site administrator and therefore can not be shown inline until you "Unlink" it. You should perform the following steps for each such certificate:
- Scroll down to the bottom of the page and copy the content of
- element in metadata.
- Paste the certificate content into an empty textarea.
- Click the "Unlink from the metadata" link.
- Submit an update request to your site administrator.
Once your site administrator approves the request, the certificate will appear inline where it is more easily reviewed and manipulated.
For delegated administrators, the Federation Manager recognizes federated credentials only (no local credentials are issued to delegated admins). Currently there are no explicit assurance requirements associated with the federated credentials of delegated administrators. Since a trusted site administrator must approve any metadata update request submitted by a delegated administrator, the approval process mitigates any weakness in the delegated administrator's login credentials.
