## Overview
|
||||
|
||||
The experimental SAML provider allows authentication through the SAML 2.0 HTTP POST binding.
|
||||
The SAML provider allows authentication through the SAML 2.0 HTTP POST binding. The connector maps attribute values in the SAML assertion to user info, such as username, email, and groups.
|
||||
|
||||
The connector uses the value of the `NameID` element as the user's unique identifier which dex assumes is both unique and never changes. Use the `nameIDPolicyFormat` to ensure this is set to a value which satisfies these requirements.
|
||||
|
||||
Unlike some clients which will process unprompted AuthnResponses, dex must send the initial AuthnRequest and validates the response's InResponseTo value.
|
||||
|
||||
## Caveats
|
||||
|
||||
There are known issues with the XML signature validation for this connector. In addition work is still being done to ensure this connector implements best security practices for SAML 2.0.
|
||||
__The connector doesn't support refresh tokens__ since the SAML 2.0 protocol doesn't provide a way to requery a provider without interaction. If the "offline_access" scope is requested, it will be ignored.
|
||||
|
||||
The connector doesn't support signed AuthnRequests or encrypted attributes.
|
||||

||||
The connector doesn't support refresh tokens since the SAML 2.0 protocol doesn't provide a way to requery a provider without interaction. Ensure that the "offline_access" scope is not requested in client apps.
