The third set of allowed characters at the end includes $. The set
[a-zA-Z0-9_.$-]? has '?' qualifier which means it is optional. But end
result is to allow '$' as the last character of a group or user name.

However, '$' is not allowed anywhere else. This makes possible to have
machine or trusted domain accounts for Active Directory/Samba purposes
but nothing else with '$' sign in the name.
