Universal groups and Domain local groups for a given user?

[Ram]

Does samba returns the universal groups for the user using wbinfo or 
some other command?

Does samba rettun the domain local group assigned to user for trusted 
domain?
Suppose we have a forest with two domains A and B. Doamin B has a domain 
local group of 'grpB'. Domain A has a user called 'user1' and it is a 
member of "DomainB/grpB". Does samba return the above group when queried 
   for the groups of "user1"?

Thanks for your help.
