=== SAML v2.0 Identity Providers
|
|
|
|
{project_name} can broker identity providers based on the SAML v2.0 protocol.
|
|
|
|
To begin configuring an SAML v2.0 provider, go to the `Identity Providers` left menu item
|
|
and select `SAML v2.0` from the `Add provider` drop down list. This will bring you to the `Add identity provider` page.
|
|
|
|
.Add Identity Provider
|
|
image:{project_images}/saml-add-identity-provider.png[]
|
|
|
|
The initial configuration options on this page are described in <<_general-idp-config, General IDP Configuration>>.
|
|
You must define the SAML configuration options as well. They basically describe the SAML IDP you are communicating with.
|
|
|
|
.SAML Config
|
|
|===
|
|
|Configuration|Description
|
|
|
|
|Single Sign-On Service URL
|
|
|This is a required field and specifies the SAML endpoint to start the authentication process. If your SAML IDP publishes an IDP entity descriptor, the value of
|
|
this field will be specified there.
|
|
|
|
|Single Logout Service URL
|
|
|This is an optional field that specifies the SAML logout endpoint. If your SAML IDP publishes an IDP entity descriptor, the value of
|
|
this field will be specified there.
|
|
|
|
|Backchannel Logout
|
|
|Enable if your SAML IDP supports backchannel logout.
|
|
|
|
|NameID Policy Format
|
|
|Specifies the URI reference corresponding to a name identifier format. Defaults to `urn:oasis:names:tc:SAML:2.0:nameid-format:persistent`.
|
|
|
|
|Principal Type
|
|
|Specifies which part of the SAML assertion will be used to identify and track external user identities. Can be either Subject NameID or SAML attribute (either by name or by friendly name).
|
|
|
|
|Principal Attribute
|
|
|If Principal is set to either "Attribute [Name]" or "Attribute [Friendly Name]", this field will specify the name or the friendly name of the identifying attribute, respectively.
|
|
|
|
|HTTP-POST Binding Response
|
|
|When this realm responds to any SAML requests sent by the external IDP, which SAML binding should be used? If set to `off`, then the Redirect Binding will be used.
|
|
|
|
|HTTP-POST Binding for AuthnRequest
|
|
|When this realm requests authentication from the external SAML IDP, which SAML binding should be used? If set to `off`, then the Redirect Binding will be used.
|
|
|
|
|Want AuthnRequests Signed
|
|
|If true, it will use the realm's keypair to sign requests sent to the external SAML IDP.
|
|
|
|
|Signature Algorithm
|
|
|If `Want AuthnRequests Signed` is on, then you can also pick the signature algorithm to use.
|
|
|
|
|SAML Signature Key Name
|
|
|Signed SAML documents sent via POST binding contain identification of signing key in `KeyName`
|
|
element. This by default contains {project_name} key ID. However various external SAML IDPs might
|
|
expect a different key name or no key name at all. This switch controls whether `KeyName`
|
|
contains key ID (option `KEY_ID`), subject from certificate corresponding to the realm key
|
|
(option `CERT_SUBJECT` - expected for instance by Microsoft Active Directory Federation
|
|
Services), or that the key name hint is completely omitted from the SAML message (option `NONE`).
|
|
|
|
|Force Authentication
|
|
|Indicates that the user will be forced to enter their credentials at the external IDP even if they are already logged in.
|
|
|
|
|Validate Signature
|
|
|Whether or not the realm should expect that SAML requests and responses from the external IDP to be digitally signed. It is highly recommended you turn this on!
|
|
|
|
|Validating X509 Certificate
|
|
|The public certificate that will be used to validate the signatures of SAML requests and responses from the external IDP.
|
|

|
|
|
|
|
|
You can also import all this configuration data by providing a URL or file that points to the SAML IDP entity descriptor of the external IDP.
|
|
If you are connecting to a {project_name} external IDP, you can import the IDP settings from the URL `<root>/auth/realms/{realm-name}/protocol/saml/descriptor`.
|
|
This link is an XML document describing metadata about the IDP.
|
|
|
|
|
|
You can also import all this configuration data by providing a URL or XML file that points to the entity descriptor of the external SAML IDP you want to connect to.
|
|
|
|
[[_identity_broker_saml_sp_descriptor]]
|
|
==== SP Descriptor
|
|
|
|
Once you create a SAML provider, there is an `EXPORT` button that appears when viewing that provider.
|
|
Clicking this button will export a SAML SP entity descriptor which you can use to import into the external SP.
|
|
|
|
This metadata is also available publicly by going to the URL.
