Join Solaris 11 server to Active Directory using smbadm?

We are having a hard time joining our organizations Active Directory using this guide. Keep getting hit with syntax and authentication errors.

Has anyone here joined a Solaris 11 to an Active Directory using smbadm as detailed in this example? I understand that the example I cited is mainly for file sharing but would it be easier once joined to get our LDAP/AC accounts working?

I appreciate any and all feedback.
