Data Source Transformer Action

A data source transformer action transforms the input attribute names and values. It does not enforce attributes, so it will not fail the authentication.

Transforming attribute names means that an attribute named user-email, for example, can be transformed to something like email in the output. This is useful when unifying data from different account sources.

Transforming attribute values means that the data inside the attribute is transformed. The data source transformer can replace the value of a given attribute with the value of an attribute found in the data source.

It is also possible to exclude attributes from the result, simply by listing them as excluded-attributes in the configuration. This will result in them being dropped when found.

The Data Source transformer uses an attribute data source to fetch external attributes. See the data source section on how to configure the data source for attribute queries.

Transforming values using data source values

Take the email attribute, replace its value with that of the user-email attribute provided by the configured data-source:

Include additional values from datasource

To add new values that exist in the data source, simply list them as additional values:

../../_images/ds-add-config.png

As with the regex transformer, it is also possible to exclude attributes and rename the attribute names.

Configuration

The following configuration options are available:

Configuration Mandatory Description
attribute-data-source yes The data source to lookup attributes in
excluded-attributes no A list of attributes to exclude from the result
additional-attributes-to-include no A list of attributes to include from the lookup
attributes no The list of transformations to perform (see next table)

Attributes List

Configuration Mandatory Description
attribute-name yes The name of the attribute to transform. If nested, use dot notation.
transformed-attribute-name no The new name of the attribute. If left empty the same name is used. Note: the path remains the same.
use-value-of-attribute-named no The attribute from the data source to use when replacing the value.
