RDX 8000 Configure CHAP
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 Secret” to gain
access to the RDX 8000. The
“ Initia tor Secret” field is provided to allow iSCSI mutual CHAP. If mutual CHAP is selected on the Initiator, the RDX
8000 will authenticate itself with the initiator using the supplied Initiator Secret.
To enable
CHAP click the ‘Enable CHAP” check box and enter the following details in the remaining fields:
• Username – this is the username that the
iSCSI Initiator must use to gain access to the iSCSI bridge
• 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 “Target secret” field has a button located to the right of the field to toggle
display
of the actual text as it is entered or hide the text. If selected, the text will be shown for 10 seconds.
• Initiator Secret – this is the password that the iSCSI bridge will send to the iSCSI Initiator during mutual CHAP.
The Initiator secret field has a button located to the right of the field to toggle display of the actual text as it is
entered or hide the text. If selected, the text will be shown for 10 seconds.
The two
CHAP secrets must be between 12 and 16 characters long and both Initiator and Target Secrets must be
different.
