MFT LDAP Groups Question

If I have 2 AD Security Group, where I have Users assigned (some users are in Both Groups)

Some users in seperate groups

If I grant Access to a different Home Dir and Assign permission to different folder structure

does MFT application affectively only allow the users to view the more restrictive folder

Also does the MFT apply least restriction to those users in both groups

Example

I have a group that I make the Home Dir %DOMAIN-HOME% and Directory Access %DOMAIN_HOME% with RWADN-L---I

the 2nd Group Home Dir %DOMAIN-HOME%\Subfolder and Directory Access %DOMAIN_HOME%\Subfolder with RW-DN-L---I

Just wondering how MFT applies its rules for Home DIR and rights

Thanks
