This document provides information on using SP-Lite, a SAML 2.0 compliant profile-based identity provider, as your preferred Security Token Service (STS)/Identity Provider. This scenario is useful when you already have a local user directory and password store that can be accessed using SAML 2.0. This existing user directory can be used to sign in to Microsoft 365 and other resources secured by Azure AD. SAML 2.0 SP-Lite profiles are based on the widely used Security Assertion Markup Language (SAML) identity federation standard to provide a login structure and attribute exchange.

For a list of third-party identity providers that have been tested for use with Azure AD , seeAzure AD Federation Compatibility Matrix
Microsoft supports this sign-in experience as an integration of Microsoft cloud services (such as Microsoft 365) with properly configured SAML 2.0 profile-based identity providers. The SAML 2.0 Identity Provider is a third-party product, and therefore Microsoft does not support best practice implementation, configuration, or troubleshooting of it. Once the SAML 2.0 identity provider integration is properly configured, you can test the configuration using the Microsoft Connectivity Analyzer tool, described in more detail below. For more information on identity providers based on SAML 2.0 SP-Lite profiles, please contact the organization providing it.
important
For this login scenario using a SAML 2.0 identity provider, only a limited set of clients are available, including:
- Internet clients such as Outlook Web Access and SharePoint Online
- An email-enabled client that uses Basic authentication and a supported Exchange access method (such as IMAP, POP, Active Sync, MAPI, etc.). (requires an Enhanced Client Protocol endpoint implementation), which includes:
- Microsoft Outlook 2010/Outlook 2013/Outlook 2016, Apple iPhone (different iOS versions)
- Various Google Android devices
- Windows Phone 7、Windows Phone 7.8 和 Windows Phone 8.0
- Windows 8 mail client and Windows 8.1 mail client
- Windows 10 mail client
All other clients are unavailable in this SAML 2.0 identity provider login scenario. For example, a Lync 2010 desktop client cannot log in to a service using a SAML 2.0 identity provider configured for single sign-on.
Azure AD SAML 2.0 requirements
This document details the protocol and message format requirements that a SAML 2.0 identity provider must implement in order to federate with Azure AD to support sign-in to one or more Microsoft cloud services (such as Microsoft 365). The SAML 2.0 (SP-STS) subsidiary of the Microsoft cloud service used in this scenario is Azure AD.
We recommend ensuring that the output message from the SAML 2.0 identity provider is as similar as possible to the sample trace provided. Wherever possible, the specified attribute values in the provided Azure AD metadata are also used. Once you are satisfied with the output message, you can test it using the Microsoft Connectivity Analyzer as described below.
Azure AD metadata can be downloaded from this URL:https://nexus.microsoftonline-p.com/federationmetadata/saml20/federationmetadata.xmlFor China customers using China-specific Microsoft 365 instances, please use the following federation endpoint:https://nexus.partner.microsoftonline-p.cn/federationmetadata/saml20/federationmetadata.xml.
SAML protocol requirements
This section details how to combine request and response message pairs to help format messages properly.
Azure AD can be configured to work with an identity provider using a SAML 2.0 SP Lite profile with the following requirements. With sample SAML request and response messages and automated and manual testing, you can work towards interoperability with Azure AD.
signature block requirements
In a SAML response message, the Signature node contains information about the digital signature of the message itself. Signature blocks have the following requirements:
- The assertion node itself must be signed
- RSA-sha1 algorithm should be used as DigestMethod. Other digital signature algorithms are not accepted.
- You can also sign XML documents.
- The conversion algorithm must match the values in the following examples:
- The SignatureMethod algorithm should match the following example:
use
For increased security, the SHA-1 algorithm is deprecated. Be sure to use a more secure algorithm such as SHA-256. More informationcan be found.
Support Links
Links are necessary communication parameters related to transport. The following requirements apply to binding
- HTTPS is a mandatory transport.
- Azure AD requires HTTP POST to send the token during login.
- Azure AD will use HTTP POST to make an authentication request to the identity provider and REDIRECT to send a logout message to the identity provider.
required attribute
This table lists the requirements for specific attributes in SAML 2.0 messages.
| Attributes | describe |
|---|---|
| ID name | The value of this assertion must be the same as the Azure AD user's ImmutableID. It can contain up to 64 alphanumeric characters. All non-HTML-safe characters must be encoded, for example, '+' is displayed as '.2B'. |
| IDPE mail | The User Principal Name (UPN) appears in the SAML response as an element named IDPEmail User Principal Name (UPN) in Azure AD/Microsoft 365. The UPN is in the format of an email address. UPN value in Windows Microsoft 365 (Azure Active Directory). |
| edit | An identity provider URI is required. Do not reuse senders in sample messages. If you have multiple top-level domains in your Azure AD tenant, the issuer must match the specific URI settings configured for each domain. |
important
Azure AD currently supports the following NameID URI format for SAML 2.0: urn:oasis:names:tc:SAML:2.0:nameid-format:persistent.

This section provides guidance on how to configure a SAML 2.0 identity provider to federate with Azure AD to allow SAML 2.0 single sign-on access to one or more Microsoft cloud services, such as Microsoft 365. The SAML 2.0 relying party for the Microsoft cloud service used in this scenario is Azure AD.
Your SAML 2.0 identity provider must honor the Azure AD relying party information. Azure AD publishes metadata tohttps://nexus.microsoftonline-p.com/federationmetadata/saml20/federationmetadata.xml.
It is recommended to always import the latest metadata from Azure AD when configuring a SAML 2.0 identity provider.
use
Azure AD does not read identity provider metadata.
Add Azure AD as a relying party
You must enable communication between the SAML 2.0 identity provider and Azure AD. This setting will depend on your specific identity provider and you should refer to the documentation. Typically, the relying party ID is the same as the entity ID in the Azure AD metadata.
use
Verify that the SAML 2.0 IdP server clock is synchronized with an accurate time source. Inaccurate clock time can cause federated logins to fail.
Install Windows PowerShell to log in with a SAML 2.0 identity provider
After configuring the SAML 2.0 identity provider for Azure AD login, the next step is to download and install the Azure Active Directory Module for Windows PowerShell. Once installed, these cmdlets will be used to configure an Azure AD domain as a federated domain.
The Azure Active Directory Module for Windows PowerShell is a download for managing organizational data in Azure AD. This module installs a set of cmdlets in Windows PowerShell; run these cmdlets to configure single sign-on access to Azure AD and then to all subscribed cloud services. For instructions on how to download and install the cmdlets , see/poprzednie-wersje/azure/jj151815(v=azure.100)
Configure a trust relationship between a SAML identity provider and Azure AD
Before configuring federation in an Azure AD domain, you must configure a custom domain. The default domain provided by Microsoft cannot be federated. Microsoft's default domain ends with "onmicrosoft.com." Run a series of cmdlets in the Windows PowerShell CLI to add or switch domains for single sign-on.
Every Azure Active Directory domain that is to be federated with a SAML 2.0 identity provider must be added as a single sign-on domain or converted from a standard domain to a single sign-on domain. Adding or converting a domain establishes a trust relationship between the SAML 2.0 identity provider and Azure AD.
The following procedure will guide you in converting an existing standard domain to a federated domain using SAML 2.0 SP-Lite.
use
After this step, your domain may experience an outage affecting users for up to 2 hours.
Configure domains in the Azure AD directory for federation
- Connect to the Azure AD directory as a tenant administrator:
Connect to MsolService- Configure the required Microsoft 365 domains to use federation with SAML 2.0:

use
you should use$ecpUrl = "https://WS2012R2-0.contoso.com/PAOS"Only if the ECP extension is configured for the identity provider. Exchange Online clients (except Outlook Web App (OWA)) rely on POST-based activity endpoints. These rich clients can interact with Exchange Online if your SAML 2.0 STS implementation has an active endpoint similar to Shibboleth's ECP active endpoint implementation.
Once federation is configured, it is possible to switch back to "non-federated" (or "managed") mode; however, this change can take up to two hours and requires each user to be assigned a new random cloud login password. In some cases, you may need to go back to Admin to reset errors in the settings. For more information on domain transitions, see:/poprzednie-wersje/azure/dn194122(v=azure.100).
Provision user principals in Azure AD/Microsoft 365
Before users can authenticate to Microsoft 365, Azure AD must be provisioned with a user principal that matches the SAML 2.0 assertion assertion. If these principals are not known to Azure AD in advance, they cannot be used for federated login. You can use Azure AD Connect or Windows PowerShell to provision user principals.
Azure AD Connect can be used to provision security principals from on-premises Active Directory to domains in the Azure AD directory. For more details, seeIntegrate on-premises directories with Azure Active Directory.
Windows PowerShell can also be used to automatically add new users to Azure AD and synchronize changes in the on-premises directory. To use the Windows PowerShell cmdlets, you must download the取模 Azure Active Directory.
This procedure shows you how to add a single user to Azure AD.
Connect to the Azure AD directory as a tenant administrator: Connect-MsolService.
Create a new username:
New-MsolUser ` -UserPrincipalName elwoodf1@contoso.com ` -ImmutableId ABCDEFG1234567890 ` -DisplayName "Elwood Folk" ` -FirstName Elwood ` -LastName Folk ` -AlternateEmailAddresses "Elwood.Folk@contoso.com" ` -UsageLocation "US"
For more information on the "New-MsolUser" checkout process,/poprzednie-wersje/azure/dn194096(v=azure.100)
use
The "UserPrincipalName" value must match the value you send in the SAML 2.0 assertion for "IDPEmail" and the "ImmutableID" value must match the value you send in the "NameID" assertion.
Authenticating single sign-on using a SAML 2.0 identity provider
As an administrator, before authenticating and managing single sign-on (also known as federated identities), review and follow the steps in the following articles to configure single sign-on using a SAML 2.0 SP-Lite-based identity provider:
- You have reviewed the Azure AD SAML 2.0 protocol requirements
- You have configured a SAML 2.0 Identity Provider
- Install Windows PowerShell for single sign-on with a SAML 2.0 identity provider
- Configure a trust relationship between a SAML 2.0 identity provider and Azure AD
- You shared a known test username with Azure Active Directory (Microsoft 365) through Windows PowerShell or Azure AD Connect.
- Configure directory synchronizationAzure AD connection.
After configuring single sign-on with a SAML 2.0 SP-Lite based identity provider, you need to verify that it is working correctly.
use
If you're converting domains instead of adding a new domain, it can take up to 24 hours to set up single sign-on. Before validating single sign-on, you must complete the Active Directory synchronization setup, synchronize the directory, and activate the synchronization user.
Use this tool to verify that single sign-on is set up correctly
To verify that single sign-on is set up correctly, you can complete the following procedure to confirm that you can log in to the cloud service using your corporate credentials.
Microsoft provides a tool that you can use to test SAML 2.0-based identity providers. Before running the test harness, you must configure your Azure AD tenant to federate with your identity provider.
use
Connectivity Analyzer requires Internet Explorer 10 or later.
downloadConnectivity Analyzer.
Click Install Now to start downloading and installing the tool.
Select I can't federate with Office 365, Azure, or other services that use Azure Active Directory.
After downloading and running the tool, you will see the connection diagnostic window. The tool will guide you through testing federated connections.
Connectivity Analyzer will open your SAML 2.0 identity provider to log in and enter the subject credentials of the user you are testing:
In the Federation Test Login window, enter the account name and password of the Azure AD tenant configured to federate with the SAML 2.0 identity provider. The tool will attempt to log in using these credentials, and detailed results of the tests performed during the login attempt will be provided as output.
This window displays the results of failed tests. Clicking View Detailed Results displays information about the results of each test performed. You can also save the results to disk for sharing.
use
Connectivity Analyzer also tests Active Federation using WS* and ECP/PAOS based protocols. If you're not using them, you can ignore this error: Testing an active login flow with an active identity provider federation endpoint.
Manually verify that single sign-on is set up correctly
Manual authentication provides additional steps you can take to ensure that your SAML 2.0 identity provider is working correctly in many cases. To verify that single sign-on is set up correctly, follow these steps:
- On a domain-joined computer, log in to the cloud service using the same login you use with your company credentials.
- Click inside the password field. If single sign-on is configured, the password field will be grayed out and you will see the following message: "You must now log in to
”。 - Click on the login link
.If you can log in, you have set up single sign-on.

Azure Active Directory Seamless single sign-on (Azure AD Seamless SSO) automatically signs users in when they are on their corporate devices connected to your corporate network. When enabled, users don't need to type in their passwords to sign in to Azure AD, and usually, even type in their usernames.
Is SAML 2.0 outdated? ›SAML 2.0 was introduced in 2005 and remains the current version of the standard. The previous version, 1.1, is now largely deprecated.
What is the purpose of using SAML 2.0 SSO? ›SAML 2.0 (Security Assertion Markup Language) is an open standard created to provide cross-domain single sign-on (SSO). In other words, it allows a user to authenticate in a system and gain access to another system by providing proof of their authentication.
What is the difference between federated IdP and SSO? ›The key difference between SSO and FIM is while SSO is designed to authenticate a single credential across various systems within one organization, federated identity management systems offer single access to a number of applications across various enterprises.
What are the disadvantages of SAML? ›Cons: Password Storage – If you store the user passwords in your database instead of using SAML, you will need to find a way to keep those passwords secure. Otherwise, if attackers managed to gain access, they could sign in as any of the users whose passwords they know.
What is the difference between SAML and LDAP in Azure AD? ›The difference between SAML and LDAP is that SAML is designed for cloud-based connections using only an IdP and SP to communicate user data. LDAP, however, is typically used for accessing on-premises resources by installing a client on the user's device to connect with a directory service.
What is the difference between Azure Active Directory Services and Azure AD? ›
Unlike Active Directory, Azure AD does not include organizational units (OUs) and group policy objects (GPOs). To delegate user administration, AAD relies on administrative units (AUs). Similar to GPOs, device settings in Azure can be managed through Microsoft Intune and the Endpoint Manager.
Is SAML required for SSO? ›Security Assertion Markup Language, or SAML, is a standardized way to tell external applications and services that a user is who they say they are. SAML makes single sign-on (SSO) technology possible by providing a way to authenticate a user once and then communicate that authentication to multiple applications.
Is SAML 2.0 a MFA? ›MFA for SAML is a secure type of authentication that enables Multi-Factor Authentication for your users in a Single Sign-On (SSO) infrastructure. It is important to note that MFA for SAML does not add MFA to SAML itself because SAML is not an authentication protocol.
What are the two models for users to authenticate using SAML? ›There are two authentication options: Username/password (default): Your users log in via email and password. SAML SSO: Your users log in via SAML single sign-on (SSO) using your identity provider.
How does IdP authentication work? ›The IdP requests the user's username and password from the user. After the user submits valid credentials, the IdP authenticates the user. The IdP returns the successful authentication in the form of a SAML Response to the client.
What is the difference between SAML response and SAML assertion? ›A SAML response is a reaction of the IdP to SURFconext with the message that the user has been successfully authenticated (or not). A SAML Assertion is some statements done by IdP or SP: authentication, authorization and attributes.
What protocols does Azure AD SSO support? ›Azure AD supports many standardized protocols for authentication and authorization, such as SAML 2.0, OpenID Connect, OAuth 2.0, and WS-Federation. Azure AD also supports password vaulting and automated sign-in capabilities for apps that only support forms-based authentication.
