Bug 1444770

Description of problem:
*********************************
After following the steps to create a setup for block storage, the discovery of targets fails with authentication error.
When we use target-cli to do the setup the authentication steps are mentioned 
to add username and password on all the servers. But when using gluster-block 
it would be expected to take care of it, else these additional steps needs to be documented.

To continue I am going to follow the target cli steps and have authentication in place until this gets fixed.


Version-Release number of selected component (if applicable):
**********************************************
rpm -qa | grep gluster-block
gluster-block-0.1.1-1.x86_64


How reproducible:
***********************************
Always


Steps to Reproduce:
1. Create the setup for block storage
2. Execute the command to discover iscsi targets from the initiator
3.

Actual results:
********************************
It fails with authentication error.
Could not login to [iface: default, target: iqn.2016-12.org.gluster-block:30db51e5-9772-4ad7-9833-f73b74ca51b8, portal: 10.70.46.60,3260].
iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure)


Expected results:
*********************************
The authentication should succeed and targets should be discovered successfully.


Additional info:
*********************
Will be trying manually to have authentication steps in place and will update the results.
