How reproducible:
always

Steps to Reproduce:
1. config test client to register to SAM
[root@dhcp-65-26 ~]# cat /etc/rhsm/rhsm.conf
hostname = samserv.redhat.com   ---> IP:10.66.12.203
baseurl=https://samserv.redhat.com:8088
ca_cert_dir = /etc/rhsm/ca/
repo_ca_cert = %(ca_cert_dir)scandlepin-local.pem

2.Register to SAM with an account, and record the consumerID:
[root@dhcp-65-26 ~]# subscription-manager register --username=test --password=***
The system has been registered with id: 3f46e9c6-4f59-4cce-8818-f718a0d4b316

3.Check if the registeration in step 2 is successful:
[root@dhcp-65-26 ~]# subscription-manager identity
Current identity is: 3f46e9c6-4f59-4cce-8818-f718a0d4b316
name: dhcp-65-26.nay.redhat.com
org name: ACME_Corporation
org id: ACME_Corporation

4.Clean the client data:
[root@dhcp-65-26 ~]# subscription-manager clean
All local data removed

5.Check if step 4 is successful:
[root@dhcp-65-26 ~]# subscription-manager identity
This system is not yet registered. Try 'subscription-manager register --help' for more information.

6.Re-register to SAM using the recorded consumer ID and another different account:
[root@dhcp-65-26 ~]# subscription-manager register --username=admin --password=*** --consumerid=3f46e9c6-4f59-4cce-8818-f718a0d4b316


Actual results:
After the step 6, register successfully with existing consumer ID using different username and password, the output is as below:
The system has been registered with id: 3f46e9c6-4f59-4cce-8818-f718a0d4b316 

Expected results:
After the step 6, it should not be successful to register with existing consumer ID using different username and password, and the output should be as below:
invalid username or password.
