Describe the bug
Boot fails with authentication error. I encountered this issue trying to setup iSCSI for the first time. I'm booting a Fedora 39 VM on hyper-v via iPXE, without iBFT, boot cmdline includes netroot=user:pass@ip:........, target is on TrueNAS CORE 13.0-U6.1 (freebsd based).
TrueNAS wizard sets up an iSCSI portal and it allows CHAP authentication for discovery. From what I've found, it looks like that on linux only target authentication is supported by targetcli or tgtadm, so I guess this combination is not common.
Distribution used
Fedora 39
Dracut version
dracut 059-16.fc39
Init system
systemd
To Reproduce
Setup a target with discovery authentication, try to boot from it specifying netroot parameters on the kernel cmdline.
# iscsiadm -m discovery -t st -p 192.168.80.48
iscsiadm: Login failed to authenticate with target
iscsiadm: discovery login to 192.168.80.48 rejected: initiator failed authorization
iscsiadm: Could not perform SendTargets discovery: iSCSI login failed due to authorization failure
Everything works fine if I instead disable authentication discovery and enable it on the target itself. To better explain the setup, here is the TrueNAS documentation: https://www.truenas.com/docs/core/13.0/uireference/sharing/iscsi/iscsishare/#manual-setup-screens
Expand the manual setup screens, the Portal tab contains the setting (Discovery Authentication Method) that caused this issue. The other authentication I'm referring to is under Targets tab (Authentication Method)
