How to use SAML Multivalued attributes - which documentation?

Hi,

 

I'm new to devcentral so apologies if this is an obvious one.

 

Another article points to saml multivalue attributes being support in V12:

 

https://devcentral.f5.com/questions/saml-multivalued-attributes-rfe

 

Where is the best place to look for the documentation on the functions the author is referring to? i.e. This is stated: "Currently the only way to forward such AD query result is to put it in an attribute as below:" ...

 

My question is what piece of f5 documentation should I be reading to find out that same information about supplying multivalued attributes to a SAML IdP configuration?

 

Thankyou for any tips!
