However, if discovery uses one username/password and the target uses different credentials, then the initiator fails to connect, ending with the messages:

Of course, Windows with the iSCSI 2.0 from Microsoft is working perfectly, using different discovery and target credentials, connecting to either the MSA1510i or the Linux iSCSI targets.

I do not think this is possible with linux-iscsi. You might be able to
do this:

DiscoveryAddress=192.168.10.94
  IncomingUsername=mary
  IncomingPassword=kdhjkd9l

The above line will set the CHAP settings for that discovery address and
targets discovered from it.

TargetName=iqn.1987-05.com.cisco:00.0d1d898e8d66.t0
  IncomingUsername=mary2
  IncomingPassword=9089080

But for many other values if you do something like the above, it will
override global settings for that specific target.
