SESSION AUTH-BLOB Attribute¶

AUTH-BLOB is a custom attribute to the 4GL handle SESSION. It's specific to the FWD framework and offers a read-only access to a free form text provided by the customer implementation of the SsoAuthenticator plugin or the 4GL code during session forking.

Attribute Type: CHARACTER.

With SSO enabled, the custom Java implementation of the SsoAuthenticator interface can populate the result of the web authentication request with a free form text that can be used for further in-app authentication or configuration of the client by assigning value to the field SsoAuthenticator.Result.authBlob. The value of the field is not used by FWD, so the text can be anything. The value is accessible in 4GL via the read-only attribute SESSION:AUTH-BLOB.

When forking a new session the SsoAuthenticator is not called, so to access the same SESSION:AUTH-BLOB it needs to be provided as an argument to the method SESSION:NEW-SESSION. See SESSION NEW-SESSION Method and Web Session Forking.

The value is by default unknown (?) and is only populated when the customer code (SsoAuthenticator plugin or 4GL call to SESSION NEW-SESSION) sets the value.
