Solaris 11 client

I have installed RedHat IDM in our environment and created a Trust with our AD domain.
RedHat clients machines can authenticate users who are using their AD userid and passwords.
I can not get my Solaris 11 clients to see AD users. The Solaris clients can authenticate users defined in IDM without issue. The Solaris machines can use the IDM defined auto mount maps fine.
Can someone point me at some docs about configuring Solaris 11 clients?
