Dear Open-E Team

Im using open-e iscsi r3 since one year. at the beginning, the product worked fine (expect performance). now i have problems adding new iscsi targets. im unable to connect to the iscsi server. (windows and linux)
i receive on both operating systems the error message "unable to authenticate" even i have deactivated chap authentication on both sides!

Im using the following open-e software release:
Model: iSCSI-R3
Version: 2.32.DB00000000.2863
Release date: 2007-09-27


Open-E Lun Config:
100GB LUN
IP Restriction: Allow 10.0.254.11
Deny 0.0.0.0/0
No Chap authentication


Linux iscsi.conf:
node.startup = automatic

# *************
# CHAP Settings
# *************

# To enable CHAP authentication set node.session.auth.authmethod
# to CHAP. The default is None.
node.session.auth.authmethod = None

# To set a CHAP username and password for initiator
# authentication by the target(s), uncomment the following lines:
#node.session.auth.username = vmware-01
#node.session.auth.password = vmware1234567890

# To set a CHAP username and password for target(s)
# authentication by the initiator, uncomment the following lines:
#node.session.auth.username_in = username_in
#node.session.auth.password_in = password_in

# To enable CHAP authentication for a discovery session to the target
# set discovery.sendtargets.auth.authmethod to CHAP. The default is None.
#discovery.sendtargets.auth.authmethod = CHAP

# To set a discovery session CHAP username and password for the initiator
# authentication by the target(s), uncomment the following lines:
#discovery.sendtargets.auth.username = vmware-01
#discovery.sendtargets.auth.password = vmware1234567890

# To set a discovery session CHAP username and password for target(s)
# authentication by the initiator, uncomment the following lines:
#discovery.sendtargets.auth.username_in = username_in
#discovery.sendtargets.auth.password_in = password_in

iscsiadm output:
[root@vmware-01 ~]# iscsiadm -m discovery -t sendtargets -p 10.0.254.1
iscsiadm: Login failed to authenticate with target
iscsiadm: discovery login to 10.0.254.1 rejected: initiator error (02/01), non-retryable, giving up


What's going wrong?!
