iSCSI CHAP authentication problem - windows

[zveky]

Adding target without CHAP works fine but I want to add authentication.

I added iSCSI user
Group ID : 1
user : I tried normal user and iqn user
secret : CHAP password have 12 characters.

On iSCSI Target I set
Auth method : CHAP
Authentication Group number : 1

# windows

c:\>iscsicli QAddTargetPortal target.tld user pass(12 characters)
Microsoft iSCSI Initiator Version 6.1 Build 7601

Authentication Failure.
