About me: I am a beginner to MS ACCESS 2010.

Ultimate goal:

I have users table created in the current MS access 2010 application.It has group A and Group B users.
Based on the type of users, I want the users to see the subforms and/or the fields in the forms.

Users authentication information is sent from the "windows authentication".That is when the
user named "John Smith" logs in using windows authentication and if the "John Smith" is
in the users table of MS ACCESS 2010 application and if he belong to group A then show the selected subforms.

May I know how to implement it ? I really appreciate it and thanks !!

Thanks,
Ram
