Security Assertion Markup Language (SAML) is an XML-based specification for exchanging authentication information online, typically to establish single sign-on (SSO) and single logout. This article describes how SAML works with Appian and how to configure SAML in the Admin Console.
For information about how to migrate to Admin Console, see Migrating SAML Configuration to the Admin Console.
For information about multi-factor authentication, see Configuring Multi-Factor Authentication.
In the SAML specification, there are three roles:
Principal (User): The client attempt to connect to a service.
Identity Provider (IdP): The provider of identity information and authentication.
Service Provider (SP): The provider of the requested service.
Using the SAML model, the user attempting to connect to Appian is the Principal (User), Appian is the Service Provider (SP), and the customer is the Identity Provider (IdP).
For a typical SP-initiated login, when a user attempts to connect to Appian, Appian redirects the user's browser to the IdP. The IdP makes an authentication decision and returns that decision to the user's browser, which then sends that decision to Appian. Appian acts on that decision, either permitting or denying the user access to the requested resource without the user having to manually sign in.
The sequence diagram below offers more specificity to SP-initiated login process.
Note: Appian also supports IdP-initiated login, but not from embedded environments or mobile.
The login.microsoftonline.com authentication flow is not supported in an iframe from Appian Embedded interfaces.
Appian also supports single logout, which is the ability have a user log out of one system behind SSO, and have that cause the user to also be logged out of other systems behind the same SSO. Not all identify providers support single logout.
Single logout can be initiated either by Appian, referred to as "SP-initiated logout," or by the identity provider or other systems behind SSO, which are both refered to as "IdP-initiated logout."
For IdP-initiated logout, Appian invalidates the session for the user that made the logout request.
For SP-initiated logout, Appian includes a SessionIndex and NameId in the SAML LogoutRequest, which indicates to the IdP which user's sessions should be ended.
All communications between the Appian and the IdP (for both sign-in and sign-out) must be performed with signed SAML assertions. If Appian receives an unsigned SAML assertion from the IdP, Appian will reject it. Appian supports SAML-based SSO using the SAML 2.0 specification and SHA-256 signature method algorithm.
To configure Appian to work with SAML, you will need:
A SAML identity provider using SAML 2.0 and SHA-256 signature method algorithm. Appian supports signed, encrypted SAML assertions up to the AES-256 standard. In order to make use of this capability, the Appian environment must be running on an Appian Cloud instance. Otherwise, self-managed Appian environments will need to be running OpenJDK 8 or have the JCE security jar installed for the Oracle Java JDK.

You can add multiple identity providers and configure the per-IdP settings differently for each.
For example, if you want to enable remember me for certain groups and disable it for others, add two identity providers. Configure different authentication groups for each identity provider. For one of the identity providers, enable remember me. For the other, disable remember me.
To add a SAML identity provider:
Adding additional IdPs is just like adding the first. Simply follow the steps outlined above to add additional ones. At the same time, keep the following items in mind while adding additional IdP:
When you have multiple IdPs configured, your IdPs should all be using authentication groups, and no user should be in multiple authentication groups. If, however, a user is in multiple authentication groups, the order of the IdPs in the grid determines which IdP a user will be able to sign-in with. Groups higher in the list have higher priority.
Caution: Priority ordering is intended to be used as a fallback in case of error. Reordering IdPs with improperly governed authentication groups can result in inadvertently giving a user access to the wrong account if your IdPs have conflicting usernames.
This section describes the settings available on the main SAML Authentication page. These settings apply to the entire environment.
Select this to use SAML to authenticate users. If not selected, all other fields on this page are disabled.
Enable this setting if you want Appian to use cookies to determine where users should be sent to sign-in.
Enable this setting if you want Appian to enable the OAuth 2.0: SAML Bearer Assertion Flow for users in the OAuth 2.0 SAML Bearer Assertion Users system group.
When selected, unauthenticated users are sent to the chosen sign-in page if they have neither a Web Address Identifier in their URL nor a browser cookie. In the dropdown, you can choose between any of your IdP sign-in pages and Appian's native authentication sign-in page.
See Choosing a default sign-in page for more information.
Note: This behavior applies to both SAML and OpenID Connect authentication.
When selected, unauthenticated users are sent to the sign-in page selection screen if they have neither a Web Address Identifier in their URL nor a browser cookie on their browser. This is a screen that allows users to identify which sign-in page they use based on administrator-configured prompts and links.
This screen should be used as a fallback for users signing-in through SP-initiated sign-in. Ideally, users should only see this screen once and use cookies for future unauthenticated requests.
See Choosing a default sign-in page for more information.
Note: This behavior applies to both SAML and OpenID Connect authentication. However, you must have at least one IdP configured to use SAML in order to have users choose their sign-in page.
Enter the text to display to the user as a prompt to assist them in choosing their sign-in page. This text appears at the top of the sign-in page selection screen.
Enter the identity providers that you want to appear in the sign-in page selection screen.
To add a new identity provder link to the sign-in page:
To remove an identity provider from the list, click X.
An IdP can appear on the page multiple times or no times, depending on your business need. If multiple sets of users sign-in through the same IdP, for example Contractors and Partners, you may want a link for each of them to assist in their selection. If all users of one type, for example internal users, sign-in through IdP-initiated sign-in or embedded, omit them from the list.
This section describes the settings that apply to specific identity providers. These settings are available when you edit an existing identity provider, or when adding a new identity provider.
Enter a Description to identify this IdP in the grid of all SAML IdPs.
Pick a short description that will help other administrators identify the IdP. The description has no other functional impact.
Add a Web Address Identifier if you do not plan on setting this IdP's sign-in page as default.
The Web Address Identifier allows users access their specific sign-in page using a URL on both web and mobile devices. If a user has a valid Web Address Identifier to their url, they will be routed to the corresponding sign-in page and bypass the default sign-in pageand sign-in page selection screen.
For example, if you have an IdP with the Identifier set to "employee", users can get to that identity's sign-in page by adding "signin=employee" to their url. So, if a user wanted to get to the Appian Designer through that IdP, they would follow the url "https://mysite.appiancloud.com/suite/design?signin=employee".
The web address identifier for OpenID Connect is "oidc".
Enable this setting to enable sign-in page cookies for this IdP.
Add an Authentication Group containing all users that should authenticate through this IdP.
Although this field isn't required if you want all users to authenticate through this IdP, it is best practice. This will make adding an additional IdPs simpler. We recommend you have at least one administrator account that does not authenticate through SAML so that you can never lock yourself out of Appian.
We strongly recommend you assign each identity provider a group to prevent being locked out of their site.
When selected, a field will appear into which you can specify one Appian user group. If the connecting user is a member of that group, they will be signed into Appian, otherwise they will see an error page telling them that they aren't authorized.
Any users who are configured to not use SAML authentication must go to /suite/portal/login.jsp.
Enter a Service Provider Name to assign Appian in the generated metadata file.
This is how you choose to label Appian in the message that will be sent to the IdP when a user attempts to sign into Appian. This should be a unique name for both the service and identity providers.
Enter a Service Provider Entity ID to assign Appian in the generated metadata file. This will typically be the Appian hostname.
Note: Some browsers will detect the Service Provider Entity ID and the Service Provider Signing Certificate Password fields as username and password fields, and may auto-populate those fields. Be sure to clear any pre-populated fields on this form.
Upload a PEM-formatted certificate for Appian to use when communicating with the IdP. In SAML, all communications between the SP and IdP are signed.
If the certificate requires one, enter the Service Provider Signing Certificate Password. This is the password Appian uses to open the certificate to use it. Leave this blank if none is required.
After all Service Provider settings are complete, you should find some metadata in the Generated Metadata field. This will provide a link to download an XML file with the required connection information you'll need in your IdP. Upload that file to your IdP.
Make sure that the metadata file uploaded to Appian is consistent with the configurations defined with the identity provider. Specifically, the entity ID or issuer ID in the uploaded IdP metadata file must match the issuer ID found in the SAML response.
Appian requires the entity ID within IdP metadata files to be unique across multiple SAML configurations. Attempting to upload IdP metadata files containing identical entity IDs will result in an error and be prevented by the system. Do not manually modify an IdP metadata file prior to uploading to Appian in order to circumvent this restriction, or users may be unable to access Appian.
Upload the Identity Provider Metadata for the identity provider being connected to Appian.. This file will contain things like the address of the IdP and its supported protocols.
Use these settings to indicate where the Appian username is provided in the SAML assertion.
This option tells Appian to use the subject attribute from the authentication response.
If the username that you want to use is in the subject of the assertion (line 4), leave this box checked. If the username that you want to use is not what is in the subject of the assertion and is instead included as an attribute (line 16), uncheck this box.

This field is only enabled if AttributeValue of Username Attribute is selected for the Username Location. Set this value to the name of the attribute that holds the username in your IdP's SAML assertion.
When "Retain Casing" is selected, Appian will use only the exact casing of the username provided by the IdP when logging into Appian or when looking up accounts. When "Use Lowercase" is selected, Appian will attempt to use both the original casing and the lowercase casing of the username sent by the IdP.
For example, if "Use Lowercase" is selected and Appian receives the username John.Doe, it will attempt to treat it as john.doe.
Select the SAML authentication context class, which is the minimum authentication method that the IdP will accept. See Authentication Context for the OASIS Security Assertion Markup Language (SAML) V2.0 for more information about the options.
If your IdP uses NTLM authentication, select this box.
Remember me enables users to sign in once and stay signed in for a specified number of days. Administrators control whether this is enabled in web browsers only, Appian Mobile only, or both. They also control the number of days that users are remembered since their last sign in.
Remember me does not apply to Administrators. Administrators are automatically logged out when their session expires, which is based on the Session Timeout period.
For more information about remember me, including best practices, see the Authentication page.
Select this if you want all users configured for this identity provider to not have to sign in for the specified number of days after their last sign in. Only affects users who sign in through a web browser.
Enter the number of days after the last sign in that users will be remembered when they log in via a browser. Must be between 1 and 90 days.
Select this if you want all users configured for this identity provider to not have to sign in for the specified number of days after their last sign in. Only affects users who sign in on the Appian Mobile app.
Enter the number of days after the last sign in that users will be remembered when they log in via the Appian Mobile app. Must be between 1 and 90 days.
Appian has the ability to inspect a SAML login response and synchronize a user's group memberships based on an assertion in the response.
For each identity provider, only groups of a single group type will be synchronized. Users will be added to any groups of this type that have an attribute value that matches the values in the SAML assertion and removed from any groups of this type that do not have a match. If there is no Appian group that matches a value in the SAML assertion, that value will be ignored and the other remaining groups that do match will synchronize. The synchronizing process will not create an Appian group if one is missing.
Because users who authenticate with remember me will not trigger a group membership synchronization if they already have a valid authentication token, you may want to consider disabling remember me if you need group membership to be up to date. See Authentication for more information.
When selected, Appian will update a user's group memberships when they sign it.
Select the group type that contains the groups that are eligible for membership synching.
Enter the name of the group type attribute that should be matched against the SAML attribute values. In the below image, memberOfValue.
Enter the name of the SAML attribute that identifies the list of groups the user's groups. For example, member-of:

Appian can sync user data included in SAML assertions with a user's profile in Appian.
When selected, if the connecting user does not have an Appian account, one will be created for them. Account creation requires that the username, first name, last name, and email address attributes be populated. Users will be automatically added to the authentication group for the identity provider when they are created.
When selected, if the connecting user already has an Appian account, attributes from the SAML assertions will be copied into the user's Appian profile.

This section describes the configurations that determine the logic for routing unauthenticated users to the correct sign-in page. When you have multiple IdPs connected to Appian, it's important to read and understand this section.
Appian has the ability to store non-expiring cookies on users' browsers that tell Appian where the user should sign in.
There are two settings that affect sign-in page cookies:
A cookie is set when a user successfully signs-in through an IdP that has Remember user's IdP selection enabled or when the user signs-in through the Appian native sign-in page when Remember IdP selection for non-SAML users is enabled. When someone with a cookie navigates to an Appian URL without a session, Appian will use the cookie to redirect the browser to the correct sign-in page for the user that last signed in with that browser. Appian will ignore the cookie if that sign-in page no longer has the feature enabled.
This feature creates a superior experience for users that leverage SP-intiated sign-in, but it can be problematic if you have users across different IdPs sharing the same computer as it is hard to recover from. If that is the case for your system, disable the feature for those users' IdPs.
For example, imagine a company with 3 IdPs: A, B, and C. IdP A is used by internal users that never interact with external users. External users, however, are split between IdPs B and C, and the company cannot guarantee that those users won't share a computer. So, the correct course of action would be to enable sign-in page cookies for IdP A but disable them for IdPs B and C.
You can choose for unauthenticated users to either Use a default sign-in page or Have users choose their sign-in page. See the linked sections for more information about both of these options.
Note: This configuration applies to both SAML and OpenID Connect authentication.
Login.gov is an identity provider used by organizations associated with the United States federal government. Appian is compatible with Login.gov's SAML identity provider.
The following instructions assume that you have already registered your Appian instance with Login.gov with the identity protocol set to saml. See the Login.gov documentation for more information on registration and on-boarding with Login.gov.
To use login.gov as an Identity Provider:
http://idmanagement.gov/ns/assurance/loa/1 or http://idmanagement.gov/ns/assurance/loa/3 (these are the only two authentication context classes compatible with Login.gov).
http://idmanagement.gov/ns/assurance/loa/1), make sure the Create New Users Upon Sign-In checkbox is unchecked. User creation is not available with this selection because Login.gov will not provide the necessary user information when this is selected. If the checkbox is checked, users will not be able to authenticate using Login.gov, even if they already exist in Appian.http://idmanagement.gov/ns/assurance/loa/3), check the Create New Users Upon Sign-In checkbox to allow users to be created in Appian the first time they sign in. Set the following fields to the attributes names that Login.gov returns in the SAML response:
emailfirst_namelast_nameemail in order to use the user's email address as the Appian username. Otherwise, Login.gov uses UUIDs for for the NameID in the SAML response, which would cause Appian to use the same UUID for the Appian username on user creation.Notes about using Login.gov as an identity provider:
SAML for Single Sign-On
