Service Providers are web applications, resources, or other services which require authentication. Strictly speaking, SAML assertions don't have to contain a name identifier. The Shibboleth project grew out of Internet2. Shibboleth allows one to authenticate using a local institutional service (IdP) to gain access to remote resources and services (SPs). Shibboleth has been adopted by the University of California as the basis for federated Single Sign-On between the UC campuses. Note that service providers can configure access to their applications from any or all of the community members associated with the higher-ed IdPs. How Shibboleth Works: Basic Concepts. web single sign-on for intranets as well as across organizational boundaries.

ECP is being focused on in the worldwide higher-ed community as technology to provide federated acccess for non-web clients - a very promising and desirable feature. SAML (security assertion markup language) technology is an XML-based protocol and OASIS standard used to exchange authentication and authorization information securely in a variety of environments. A successful deployment of Shibboleth involves two critical software components: This is the server that handles authentication of users. Shibboleth has been adopted by the University of California as the basis for federated Single Sign-On between the UC campuses. Unfortunately this generality makes interoperability much more complex than one would prefer. Commercial SAML deployments less commonly make use of Attributes and tend to use loosely or improperly specified name identifiers. A name identifier, represented by the element in SAML1 and the element in SAML2, is a direct way to name the subject of a SAML assertion. It enables the following features: OASIS privides a concise, easy to read technical overview of SAML and its use cases here: http://www.oasis-open.org/committees/download.php/27819/sstc-saml-tech-overview-2.0-cd-02.pdf. In SSO use cases, one reason for including an identifier is to enable the relying party to refer to the subject later, such as in a query, or a logout request. IdPs and SPs listed in the metadata file typically form a federation. Free whitepaper – SAML vs OAuth vs OpenID Connect Free Trial – IDaaS (experiment with SSO, Authorization, Authentication, & Identity Providers as-a-service) In this blog entry we’ll take a little deeper look at the most prevailing standards for the use case of granting access to an online application. Shibboleth is an open-source project that provides Single Sign-On capabilities and allows sites to make informed authorization decisions for individual access of protected online resources in a privacy-preserving manner.

It is being deployed at the University to provide webSSO services. The second is rich client access for IMAPS and ActiveSync clients via the SAML Enhanced Client Proxy (ECP) profile. the service provider (SP): This component is bound to the web service or server that is implementing access control. Shibboleth is a web-based Single Sign-On infrastructure.

A Phone Number is not universally portable but within the US, Phone Number is indeed a portable identifier.

Note that this service will replace the use of Pubcookie as the underlying webSSO technology. Shibboleth is a web-based Single Sign-On infrastructure. Our local UC Berkeley authentication provider is based on CAS backed by CalNetAD and LDAP. What distinguishes Shibboleth from other products in this field is its adherence to standards and its ability to provide SSO support to services outside of a user’s organization while still protecting their privacy. Shibboleth deployments traditionally have focused on the use of Attributes to describe subjects, and default to the use of transient name identifiers (or omitting them). Shibboleth IdPs and SPs securely exchange authentication, authorization and configuration information with one another via an xml metadata file. For more information: Access to the Microsoft live@edu service is provided using SAML and Shibboleth. integrated authentication and authorization services. An IdP is useless without Service Providers. the identity provider (IdP): This component is associated with the institutional identity and access management resources and is used to manage user authentication sessions and supply attributes bound to the user to service providers for authorization. Here are some examples (not all of these are actually encoded as SAML name identifiers, some are defined solely as Attributes): In SAML, subjects are also commonly described with Attributes. The CAF is a Canada-wide SAML federation operated by CANARIE. SAML 1.x Browser-POST and Browser-Artifact profiles. support for a federated identity - an identifier that can be used to map the identity of users outside an organization to a local user account. The following site provides complete documentation and information on Shibboleth: At the University of Toronto, there are three Shibboleth federations in service: To install, configure and operate a shibboleth service provider under weblogin, consult the documentation page here: http://sites.utoronto.ca/security/projects/sp-install.htm. It consists of three functional parts: Shibboleth IdPs and SPs securely exchange authentication, authorization and configuration information with one another via an xml metadata file. Only one IdP is needed per campus. There are two components to the design - the first is regular web access via the SAML HTTP/POST profile.

In fact, it is one of the few portable identifiers with no qualifier. Name identifiers can be anything: an email address, a Kerberos principal name, a certificate subject, an employee ID, a username, or literally anything else. UC Berkeley has deployed an IdP at shib.berkeley.edu. Please email the following with details: For ITS - EASI developer staff, please consult the following to make use of the development shib environment: http://sites.utoronto.ca/security/projects/EASI-dev.htm. If you have a service that has a configuration for external SSO / SAML, see "How to setup SSO/SAML with your service.". Examples of SPs are: UCReady, the UCB Learning Center (a SumTotalSystems application hosted at UCOP by SumTotalSystems), and At Your Service (AYSO, hosted at UCOP).

SAML 2.0 also defines more specialized identifier types with particular properties that were presumed useful in federated applications. the browser: The client is normally a web browser although SAML does support enhanced clients and proxies. It is based on SAML, a standard for the exchange of authentication data. They're conceptually similar to an Attribute Name and in fact one conventional way to express a SAML Attribute as a name identifier is to encode its Name as a Format (assuming the Attribute Name is a URI). We’ll discover what is the difference between SAML 2.0 and OAuth 2.0. So-called "transient" identifiers that are generated uniquely for each assertion are often used to support those use cases and are a common pattern in Shibboleth deployments. In practice, the scope value is a DNS domain, which ensures global uniqueness.

The Shibboleth SP software allows most web servers (namely Apache and IIS) to integrate with an IdP or a number of IdPs. Commercial SAML deployments less commonly make use of Attributes and tend to use loosely or improperly specified name identifiers. University of Toronto webSSO federation (known as the UTORauth weblogin service ): this consists of the production IdP service run by ITS and SPs run by University departments and divisions. Copying over a comment from the old NameID page from David Macdonald... A few references for questions around ORCiD: Powered by a free Atlassian Confluence Open Source Project License granted to Shibboleth. Please see the iNews articles on Federated Identity Management at UC Berkeley for more information.

Of course, many attributes are not identifiers at all, merely data of various kinds. A federation is mainly a trust relationship, for example membership in the federation extends access to default user attribute information that can be used for authorization checking. Evaluate Confluence today. To use attributes supplied by the IdP, consult the following page: http://sites.utoronto.ca/security/projects/sp-attribute-config.htm. Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.

For example, SAML messages are usually digitally signed, and can be encrypted. Every name identifier is associated with a format.

Indeed, the value of the latter is precisely a SAML2 Persistent, The SAML2 Persistent name identifier (and hence eduPersonTargetedID) are portable in the sense that any issuer can assert a known SAML2 Persistent, The SAML2 Persistent name identifier and the OIDC pairwise.

Shibboleth is an open source software product that implements SAML (Security Assertion Markup Language). Shibboleth deployments traditionally have focused on the use of Attributes to describe subjects, and default to the use of transient name identifiers (or omitting them).

Two of the most popular software components managed by the Shibboleth Consortium are the Shibboleth Identity Provider and the Shibboleth Service Provider, both of which are implementations of SAML. the browser: The client is normally a web browser although SAML does support enhanced clients and proxies. IdPs and SPs listed in the metadata file typically form a federation. Shibboleth allows one to authenticate using a local institutional service (IdP) to gain access to remote resources and services (SPs). The SP software consists of several components: Information Security & PolicyTechnology@BerkeleyCal 1 Card OfficebConnectedStudent Information Systems ProjectOffice of the Registrar, Copyright © 2020 UC Regents; all rights reserved, Request to Require 2-Step for Your Service, Federated Identity Management at UC Berkeley. It is based on SAML, a standard for the exchange of authentication data.

The properties above used to describe name identifiers also apply to attributes when those attributes are themselves unique identifiers for a subject. Canadian Access Federation: this consists of IdPs from higher-ed institutions across Canada and SPs for higher-ed institutions and commercial service providers.

In contrast to name identifiers, SAML Attributes can have multiple values and aren't necessarily usable as identifiers, but any name identifier can usually be expressed as an Attribute. Though this is a retroactive view of the design, Name identifiers can be described by the following characteristics: A special type of globally unique identifier is a scoped attribute, which has the form userid@scope. For general background and detailed documentation directly from the Shibboleth Project, see Understanding Shibboleth. Formats label the identifier at runtime to help applications process them appropriately. {"serverDuration": 217, "requestCorrelationId": "9cb5058891954e0c"}, Creative Commons Attribution-ShareAlike 3.0 license, The SAML2 Persistent name identifier and the eduPersonTargetedID attribute are functionally equivalent. There are over a dozen higher-ed IdPs and a number of commercial SPs participating. live@edu federation: this is a bilateral federation between the University and Microsoft for the purpose of providing access to the UTMail+ service. As a protocol handler, an entityID … Our local UC … Security of messaging between IdP and SPs is mainly handled by applying cryptography at various levels. The subject may be implicitly identified as the bearer of the token or anybody able to demonstrate possession of a key.
