How to increase the number of allowed chars in Group name (pre Windows 2000)

When you create a new Active Directory group or edit group properties in the Web Portal you can get the error: String is too long (maximum 20 chars) in the Group name (pre-Windows 2000) field.

Cayosoft Administrator has 20 characters limitation because it is recommended by Microsoft in case of backward compatibility, the details you can get from this article: SAM-Account-Name attribute.
