Advanced OpenID Connect Configurations¶
This page lists out all the advanced configurations related to OAuth/OpenID Connect authentication.
Selecting OAuth Version as 1.0a removes all the configurable Allowed Grant Types. This is because this version of OAuth does not support grant types.
Allowed Grant Types¶
The following grant types can be used to generate the access token.
Code: Entering the username and password required at the service provider will result in a code being generated. This code can be used to obtain the access token. For more information on this grant type, see Authorization Code specification.
Password: This grant authenticates the user using the password obtained and provides the access token. For more information on this grant type, see Resource Owner Password Credentials Grant specification.
Implicit: This is similar to the code grant type, but instead of generating a code, this directly provides the access token. For more information on this grant type, see Implicit Grant specification.
Client Credential: This is the grant type for the client key and client secret. If these two items are provided correctly by the service provider, the access token is sent. For more information on this grant type, see Client Credentials specification.
Refresh Token: This will enable the user to obtain an access token by using the refresh token once the originally provided access token is used up. For more information on this grant type, see Refresh Token specification.
SAML2: This uses SAML assertion to obtain the access token. For more information on this grant type, see SAML2 Bearer specification.
IWA-NTLM: This is similar to the password grant type, but it is specific to Microsoft Windows users.
urn:ietf:params:oauth:grant-type:jwt-bearer: This is a custom grant type. It uses a JWT token to obtain the access token. For more information about this grant type, see JWT specification.
This is the exact location in the service provider's application where an access token would be sent. This is a required field (if the grant type is anything other than 'Code' or 'Implicit') and it is important to configure, as it is imperative that the service provider receives the access token. This is necessary for security purposes to ensure that the token is not compromised.
Click for information on configuring multiple callback URLs
From IS 5.2.0 onwards, regex-based consumer URLs are supported when defining the callback URL. This enables you to configure multiple callback URLs for one application by entering a regex pattern as the value for the callback URL field.
For example, if you have two service providers that use the same application, you can now define a regex pattern which will work for both callback URLs instead of having to configure two different applications for the two service providers. Assume the two callback URLs for your two service providers are as follows:
Click for information on configuring loopback callback URLs
From IS 6.0.0 onwards, to comply with RFC 8252 section 7.3, the callback URL in the authorization request does not need to have an exact port match to the callback URL registered here if it is a loopback callback IP address.
Exact port matches are not required if you use loopback IP addresses (
For example, if you register a loopback callback URL
http://127.0.0.1:8090/callback the following callback URLs in the authorization requests would also be valid:
When registering multiple callback URLs using a regex pattern, do not specify the port number for the loopback callback URL either as a single port or as a capture group. An example regex pattern is as follows:
PKCE Mandatory: Select this if you are using the Code grant type. PKCE is a recommended security measure used to mitigate a code interception attack.
See Mitigating Authorization Code Interception Attacks for more information.
Support PKCE 'Plain' Transform Algorithm: Select this if you are using PKCE.
Allow Authentication without the client secret¶
This enables authenticating the client without the client secret.
Token Expiry Time¶
Set the validity period (in seconds) for the following access tokens.
- User Access Token Expiry Time
- Application Access Token Expiry Time
- Refresh Token Expiry Time
- Id Token Expiry Time
Enable Audience Restriction¶
Select this to enable audience restrictions for OAuth applications. If necessary, you can add multiple audiences. To add an audience, specify a required Audience value and click Add. All audience values that you add would be available in the ID token generated for the corresponding application.
Enable Request Object Signature Validation¶
This is to define whether to only accept signed request objects in an authorization request or not.
Enable ID Token Encryption¶
This is to define whether to ID token encryption should be enabled or not. For a tutorial on this, see Test OIDC Encrypted ID Token with IS.
Enable OIDC Back-Channel Logout¶
This is to define whether OIDC back-channel logout should be enabled or not. For more information, see Configure OpenID Connect Back-Channel Logout.
This is to define the scope validation mechanisms.
Select either JWT or Default as the token issuer for the service provider.
- If you want to enable default token generation for a service provider, select Default as the Token Issuer.
When you enable default token generation, the hash value of the token is stored in the
ACCESS_TOKEN_HASHcolumn, and the plain text token is stored in the
- If you want to enable JWT token generation for a service provider, select JWT as the Token Issuer.
When you enable JWT token generation, the hash value of the JWT is stored in the
ACCESS_TOKEN_HASHcolumn, and the full JWT is stored in the
Authorization Code Validity Period¶
This is a file configuration and does not appear on the management console.
When using the Authorization Code grant type, the received authorization code can only be used once to get a valid access token and has an expiry time. The expiry time can be configured by adding the following property to the
<IS_HOME>/repository/conf/deployment.toml file. The default expiry time is 300 seconds.
[oauth.token_validation] authorization_code_validity= "300"
