# Defining the authentication method

Note: The ServeRAID Manager supports authentication for iSCSI initiators only.

Use the Authentication information window to define the authentication method (if any) for each user permitted to use the logical drives in the array. Optionally, you can enable Radius authentication (an external authentication service) and define the SLP (Service Location Protocol) Scope name.

1. Select a logical drive from the list on the left.
2. From the Authentication type list, select the method used to authenticate users of this logical drive. You can choose:
   - None - Do not authenticate users
   - CHAP - Challenge Handshake Authentication Protocol
   - SRP - Secure Remote Password
3. If you enabled authentication (by choosing CHAP or SRP), click ; the "Global user name and password management" window opens. Then, add users to the user list.
4. To enable Radius authentication for the CHAP authentication method, click Radius authentication; then, enter the following:
   - In the Primary server field, enter the host name or TCP/IP address of the authentication service; then, in the Port field, enter the server's startup port.
   - In the Secondary server field, enter the host name or TCP/IP address of the authentication service; then, in the Port field, enter the server's startup port.

   Note: Radius authentication is supported by the CHAP authentication method only.

5. To modify the default SLP Scope name, click Advanced settings; then, in the SLP Scope Name field, type a unique scope name or choose an existing name from the drop-down list.
6. Repeat steps 1 through 5 to enable authentication for additional logical drives. To replicate the settings for all logical drives, click .
7. When you are ready to continue, click Next. The "Define initiators" window opens.

To return to the "Create logical drives" window, click Back.
To leave the Configuration wizard, click Cancel.
