To create a new group with a group key
When you click Generate, a new group key will be created using the current default settings for a group key.
When you click Import, the Import Key page appears. Select a key file or paste a key block, enter the passphrase of the private key, then click Import.
Note: To quickly create a new group from an Active Directory security group with an automatically generated group key, go to Keys > Managed Keys, click on the Generate AD Group Keys button, and follow the on-screen instructions.
