7.6.1 CHAP Settings
CHAP is an authentication scheme used by Servers to validate the identity of clients and vice versa. When
CHAP is enabled, the initiator must send the correct Username and Target Password to gain access to the
iSCSI bridge. The Initiator Secret is provided to allow iSCSI mutual CHAP. If mutual CHAP is selected on the
Initiator, the iSCSI bridge will authenticate itself with the initiator using the initiator secret.
To enable CHAP click the ‘CHAP Enabled’ tick box and enter the following details:
• Username – this is the username that the iSCSI Initiator must use to gain access to the iSCSI bridge
• Initiator Secret – this is the password that the iSCSI bridge will send to the iSCSI Initiator during
mutual CHAP
• Target Secret – This is the secret defined by the iSCSI bridge and will be sent from the ISCSI
Initiator to authenticate the iSCSI Initiator.
The two CHAP secrets must be between 12 and 16 characters long and both Initiator and Target Secrets
must be different.
