Modifying a Person Group Login
When you create a person group, the login of the group is automatically created.
From the Login properties window, you can:
modify the name of the login and the user code associated with the login
modify the status of the person group (inactive)
* 
modify authentication mode
To modify the login of a person group:
1. Access the property pages of the login.
2. Select Characteristics:
The login Name and User Code attributes are already created, but you can modify these if necessary.
*A login is unique and defined for a person or person group.
*The User code is the short identifier (upper case) of the user. It is of no use in case of a person group.
The Login Holder represents the person group associated with this login.
The value of the Status (Login) field defines if the person group is active or not.
