Setting ACLs on HomeDrive

Hi, I'm using V8.0 and I'm looking at provisioning home drives. I can see that the folder permissions are set according to some configuration parameters:

QER\Person\User\AccessRights\TerminalProfileDir\EveryOne

and

QER\Person\User\AccessRights\TerminalProfileDir\User

The default values for these look like +r+w-x. I'm guessing that this default value would give read and write permissions and deny whatever x stands for. Is there somewhere that I can lookup what values can be set in this field. I found this documentation that mentions the configuration parameters https://support.oneidentity.com/technical-documents/identity-manager/8.0/administration-guide-for-connecting-to-active-directory/15 but there's no discussion on what values can possibly be put there. What do the default values stand for and what is available for me to add in these configuration parameters?
