Thats right, citrix doens't support adding domain local groups.

Do you know why citrix doesn´t support adding domain local groups?

Or can you give me an citrix knowledge base article?

In old versions of Citrix there were also problems when using domain local groups with published applications!

This article only specifies that "Recommendation: All servers that load balance an application must be in the same domain if a domain local group is authorized to use the application." If you follow this rule, Domain Local Groups work fine. We only use Domain Local groups on our farm since we must have access groups that can cover multiple domains. Can PAU be changed to access DL groups in the near future? Because of this limitation in PAU, I cannot use it to set access for published applications.
