SSO (OIDC + SAML + LDAP)

Overview

The sso sub-client provides enterprise-grade single sign-on for your developer organization. It supports multiple identity provider connections (OIDC, SAML 2.0, and LDAP), domain-based enforcement, JIT (just-in-time) provisioning, and session management. Compatible with Okta, Azure AD, Google Workspace, Auth0, OneLogin, PingFederate, OpenLDAP, FreeIPA, and any SAML 2.0, OIDC, or LDAP-compliant provider.

// Create an enterprise SSO connection
const conn = await grantex.sso.createConnection({
  name: 'Okta Production',
  protocol: 'oidc',
  issuerUrl: 'https://mycompany.okta.com',
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
  domains: ['mycompany.com'],
  jitProvisioning: true,
});

Enterprise SSO Connections

sso.createConnection()

Create a new SSO identity provider connection. You can create multiple connections for different domains or providers.

const conn = await grantex.sso.createConnection({
  name: 'Okta Production',
  protocol: 'oidc',
  issuerUrl: 'https://mycompany.okta.com',
  clientId: 'your-okta-client-id',
  clientSecret: 'your-okta-client-secret',
  domains: ['mycompany.com', 'mycompany.org'],
  jitProvisioning: true,
  defaultRole: 'member',
});

console.log(conn.id);              // 'sso_conn_01HX...'
console.log(conn.name);            // 'Okta Production'
console.log(conn.protocol);        // 'oidc'
console.log(conn.status);          // 'active'
console.log(conn.domains);         // ['mycompany.com', 'mycompany.org']
console.log(conn.jitProvisioning); // true
console.log(conn.createdAt);       // '2026-03-29T12:00:00Z'

SAML example

const samlConn = await grantex.sso.createConnection({
  name: 'Azure AD SAML',
  protocol: 'saml',
  metadataUrl: 'https://login.microsoftonline.com/.../federationmetadata/2007-06/federationmetadata.xml',
  assertionConsumerServiceUrl: 'https://yourapp.com/sso/saml/callback',
  entityId: 'https://yourapp.com/saml/metadata',

  state: 'csrf_state',
});

console.log(result.email);        // 'alice@mycompany.com'
console.log(result.name);         // 'Alice Smith'
console.log(result.sub);          // 'okta|abc123'
console.log(result.developerId);  // 'dev_01HXYZ...'
console.log(result.connectionId); // 'sso_conn_01HX...'
console.log(result.provisioned);  // true (if JIT-created)

Parameters

code

string

required

The authorization code from the OIDC callback.

state

string

required

The state parameter from the callback (used for CSRF protection).

Response: `SsoCallbackResponse`

string | null

The user’s email address from the IdP.

name

string | null

The user’s display name from the IdP.

sub

string | null

The user’s subject identifier from the IdP.

developerId

string

The Grantex developer ID that the user has been mapped to.

connectionId

string

The SSO connection that handled this authentication.

provisioned

boolean

Whether the user was just-in-time provisioned during this login.

sso.handleSamlCallback()

Handle the callback from a SAML 2.0 identity provider. Validates the SAML assertion and provisions the user if JIT is enabled.

const result = await grantex.sso.handleSamlCallback({
  samlResponse: req.body.SAMLResponse,
  relayState: req.body.RelayState,
});

console.log(result.email);        // 'bob@contoso.com'
console.log(result.name);         // 'Bob Jones'
console.log(result.developerId);  // 'dev_01HXYZ...'
console.log(result.connectionId); // 'sso_conn_02HX...'
console.log(result.provisioned);  // false

Parameters

samlResponse

string

required

The base64-encoded SAML response from the IdP.

relayState

string

The RelayState parameter from the SAML callback.

Response

Returns the same SsoCallbackResponse as handleOidcCallback().

sso.handleLdapCallback()

Authenticate a user via LDAP bind. Unlike OIDC and SAML which use browser redirects, LDAP authentication submits credentials directly. Grantex binds to the LDAP directory, verifies the user’s password, reads their attributes and group memberships, maps groups to scopes, and provisions the user if JIT is enabled.

const result = await grantex.sso.handleLdapCallback({
  username: 'alice',
  password: 'user-password',
  connectionId: 'sso_conn_03HX...',
});

console.log(result.email);        // 'alice@mycompany.com'
console.log(result.name);         // 'Alice Smith'
console.log(result.developerId);  // 'dev_01HXYZ...'
console.log(result.connectionId); // 'sso_conn_03HX...'
console.log(result.provisioned);  // true (if JIT-created)

Parameters

username

string

required

The user’s LDAP username (e.g. uid, sAMAccountName, or full DN).

password

string

required

The user’s LDAP password for bind authentication.

connectionId

string

required

The SSO connection ID for the LDAP directory.

Response

Returns the same SsoCallbackResponse as handleOidcCallback().

LDAP credentials are never stored by Grantex. They are used only for the bind operation and discarded immediately after authentication.

  redirectUri: 'https://yourapp.com/sso/callback',
});

console.log(config.issuerUrl);   // 'https://accounts.google.com'
console.log(config.clientId);    // 'your-google-client-id'
console.log(config.redirectUri); // 'https://yourapp.com/sso/callback'
