> # Restricting iSLB Initiator Authentication

> By default, the iSLB initiator can use any user name in the RADIUS or local AAA database in authenticating itself to the IPS module or MPS-14/2 module (the CHAP user name is independent of the iSLB initiator name). The IPS module or MPS-14/2 module allows the initiator to log in as long as it provides a correct response to the CHAP challenge sent by the switch. This can be a problem if one CHAP user name and password have been compromised.

> Choose IP > iSCSI iSLB in Device Manager and set the AuthName field to restrict an initiator to use a specific user name for CHAP authentication.

> See the "Configuring iSLB Using Device Manager" procedure.
