I am trying to process a SAML attribute with multiple values.

To that end I have created a client mapper of type User Attribute with "Multivalued" on. 

I also have an "attribute importer" mapper in the SAML v2.0 identity provider. It points to user attribute name defined in the client mapper mentioned above. 

Unfortunately, it is only mapping the first value into the access token.

The attribute in the SAML response looks like this

<Attribute Name="http://cambio.se/2016-09/cds/profile"> <AttributeValue>value1</AttributeValue> <AttributeValue>value2</AttributeValue> <AttributeValue>value3</AttributeValue> </Attribute>  

In the access token only the first value appears as part of "otherClaims" map.

What do I need to do in order to get all the values in the access token?

Thanks
