Is it possible to use the security group with `$`-prefix in its name to log in to Red Hat Enterprise Linux 6 authenticating against Active Directory using winbind?

Issue

• The Red Hat Enterprise Linux 6 system is authenticating against Active directory using winbind,so that users from active directory would be able to log in to the Red Hat Enterprise Linux 6 system. There is a group having '$'-prefix to its name, for example, $-Admins.
• Can we use this $-Admin group name in winbind related congiguration files such as /etc/security/pam_winbind.conf?
