I am attempting to use a Ubuntu Server 14.04 as an iSCSI target for some Windows 7 clients. I installed targetcli on the Ubuntu Server and configured one LUN as a test.
Code:

I then enabled CHAP authentication
Code:
/iscsi/iqn.20...:sn.001/tpgt1> get attribute
authentication
authentication=1
Next I set the CHAP userid and password, but did not specify a mutual challenge.
Code:
/iscsi/iqn.20...:11ca3ce2b641> get auth
AUTH CONFIG GROUP
mutual_password=
The mutual_password auth parameter.
mutual_userid=
The mutual_userid auth
parameter.
password=Password123
The password auth
parameter.
userid=testUser1
The userid auth parameter.
When I setup the Windows 7 initiator, I specified the Name in the CHAP settings to be the same as the userid and set the Target secret to be the same as the password above.
However, when I try to do a discovery of the target from the Windows 7 initiator, the Target complains about the following found in syslog:
Code:
Jul 2 22:19:15 fmnas kernel: [819187.317599] CHAP_N values do not match!
Jul 2 22:19:15 fmnas kernel: [819187.323463] Security negotiation failed.
Jul 2 22:19:15 fmnas kernel: [819187.329365] iSCSI Login negotiation failed.
I am assuming CHAP_N is the name, but as stated above, I ensured they were the same. That is if I am doing them in the correct locations. Can anyone point me in the right direction or let me know what fundamental mistake I am doing?
I REALLY appreciate it.
