Parameters¶

name

Identifier for the integration to alter. If the identifier contains spaces or special characters, the entire string must be enclosed in double quotes. Identifiers enclosed in double quotes are also case-sensitive.

SET ...

Specifies one or more properties/parameters to set for the integration (separated by blank spaces, commas, or new lines):

ALLOWED_USER_DOMAINS = ( 'string_literal' [ , 'string_literal' , ... ] )

Specifies a list of email domains that can authenticate with a SAML2 security integration. For example, ALLOWED_USER_DOMAINS = ("example.com", "example2.com", ...).

This parameter can be used to associate a user with an IdP for configurations that use multiple IdPs. For details, see Using multiple identity providers for federated authentication.

ALLOWED_EMAIL_PATTERNS = ( 'string_literal' [ , 'string_literal' , ... ] )

Specifies a list of regular expressions that email addresses are matched against to authenticate with a SAML2 security integration. For example, ALLOWED_EMAIL_PATTERNS = ("^(.+dev)@example.com$", "^(.+dev)@example2.com$", ... ).

This parameter can be used to associate a user with an IdP for configurations that use multiple IdPs. For details, see Using multiple identity providers for federated authentication.

TYPE = SAML2

Specify the type of integration:

SAML2: Creates a security interface between Snowflake and the identity provider.

ENABLED = TRUE | FALSE

Specifies whether to initiate operation of the integration or suspend it.

TRUE allows the integration to run based on the parameters specified in the pipe definition.
FALSE suspends the integration for maintenance. Any integration between Snowflake and a third-party service fails to work.

SAML2_ISSUER = 'string_literal'

The string containing the EntityID / Issuer of the IdP.

SAML2_SSO_URL = 'string_literal'

The string containing the IdP SSO URL, where the user should be redirected by Snowflake (the Service Provider) with a SAML AuthnRequest message.

SAML2_PROVIDER = 'string_literal'

The string describing the IdP.

One of the following: OKTA, ADFS, Custom.

SAML2_X509_CERT = 'string_literal'

The Base64 encoded IdP signing certificate on a single line without the leading -----BEGIN CERTIFICATE----- and ending -----END CERTIFICATE----- markers.

SAML2_SP_INITIATED_LOGIN_PAGE_LABEL = 'string_literal'

The string containing the label to display after the Log In With button on the login page.

SAML2_ENABLE_SP_INITIATED = TRUE | FALSE

The Boolean indicating if the Log In With button will be shown on the login page.

TRUE displays the Log in With button on the login page.
FALSE does not display the Log in With button on the login page..

SAML2_SNOWFLAKE_X509_CERT = 'string_literal'

The Base64 encoded self-signed certificate generated by Snowflake for use with Encrypt SAML assertions and Send signed SAML requests.

You must have at least one of these features (encrypted SAML assertions or signed SAML responses) enabled in your Snowflake account to access the certificate value.

SAML2_SIGN_REQUEST = TRUE | FALSE

The Boolean indicating whether SAML requests are signed.

TRUE allows SAML requests to be signed.
FALSE does not allow SAML requests to be signed.

SAML2_REQUESTED_NAMEID_FORMAT = 'string_literal'

The SAML NameID format allows Snowflake to set an expectation of the identifying attribute of the user (i.e. SAML Subject) in the SAML assertion from the IdP to ensure a valid authentication to Snowflake. If a value is not specified, Snowflake sends the urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress value in the authentication request to the IdP.

Optional.

If you choose to specify the SAML NameID format, use one of the following values:

urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified
urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
urn:oasis:names:tc:SAML:1.1:nameid-format:X509SubjectName
urn:oasis:names:tc:SAML:1.1:nameid-format:WindowsDomainQualifiedName
urn:oasis:names:tc:SAML:2.0:nameid-format:kerberos
urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
urn:oasis:names:tc:SAML:2.0:nameid-format:transient

SAML2_POST_LOGOUT_REDIRECT_URL = '<string_literal>'

The endpoint to which Snowflake redirects users after clicking the Log Out button in the Classic Console.

Snowflake terminates the Snowflake session upon redirecting to the specified endpoint.

SAML2_FORCE_AUTHN = TRUE | FALSE

The Boolean indicating whether users, during the initial authentication flow, are forced to authenticate again to access Snowflake. When set to TRUE, Snowflake sets the ForceAuthn SAML parameter to TRUE in the outgoing request from Snowflake to the identity provider.

TRUE forces users to authenticate again to access Snowflake, even if a valid session with the identity provider exists.
FALSE does not force users to authenticate again to access Snowflake.

Default: FALSE.

SAML2_SNOWFLAKE_ISSUER_URL = '<string_literal>'

The string containing the EntityID / Issuer for the Snowflake service provider.

If an incorrect value is specified, Snowflake returns an error message indicating the acceptable values to use.

The value of this property must match the Snowflake account URL specified in the IdP. It defaults to the legacy URL, so if you define a different URL format in the IdP, make sure to set this property appropriately.

SAML2_SNOWFLAKE_ACS_URL = '<string_literal>'

The string containing the Snowflake Assertion Consumer Service URL to which the IdP will send its SAML authentication response back to Snowflake. This property will be set in the SAML authentication request generated by Snowflake when initiating a SAML SSO operation with the IdP.

If an incorrect value is specified, Snowflake returns an error message indicating the acceptable values to use.

Default: https://<account_locator>.<region>.snowflakecomputing.com/fed/login

COMMENT = 'string_literal'

Adds a comment or overwrites an existing comment for the integration.

Default: No value

TAG tag_name = 'tag_value' [ , tag_name = 'tag_value' , ... ]

Specifies the tag name and the tag string value.

The tag value is always a string, and the maximum number of characters for the tag value is 256.

For information about specifying tags in a statement, see Tag quotas for objects and columns.

UNSET ...

Specifies one or more properties/parameters to unset for the security integration, which resets them back to their defaults:

ENABLED
TAG tag_name [ , tag_name ... ]

REFRESH SAML2_SNOWFLAKE_PRIVATE_KEY

Generates a new private key and self-signed certificate for a SAML2 security integration. The old private key and self-signed certificate are overwritten by the new ones. For more information about best practices for rotating keys, see Manage Your SAML2 security integration.

Usage notes¶

Customers should ensure that no personal data (other than for a User object), sensitive data, export-controlled data, or other regulated data is entered as metadata when using the Snowflake service. For more information, see Metadata fields in Snowflake.
After rotating your SAML2_SNOWFLAKE_PRIVATE_KEY using the REFRESH command, you need to upload your new SAML2_SNOWFLAKE_X509_CERT value to your IdP, otherwise SAML authentication stops working. For more information about best practices around rotating keys, see Manage Your SAML2 security integration.

Examples¶

The following example initiates operation of a suspended integration:
```
ALTER SECURITY INTEGRATION myint SET ENABLED = TRUE;
```
Copy
The following example rotates the private key and generates a new self-signed certificate for a SAML2 security integration named my_idp:

Caution

After running the command below, SAML authentication stops working because your IdP still uses your old SAML2_SNOWFLAKE_X509_CERT certificate. To minimize disruptions, you should run this command when users are not as active. For more information, see Manage Your SAML2 security integration.
```
alter security integration my_idp refresh SAML2_SNOWFLAKE_PRIVATE_KEY;
```
