Solution

When connecting to RHEV Manager, you need to include domain in the user name:

• User name: DOMAIN\user
• Password: password

OR

• User name: user@DOMAIN
• Password: password

  

(!) As an additional means to solve the connection issue, try using "admin@internal" login as the user name.

=> This is a default built-in account created by Red Hat Enterprise Virtualization Manager automatically during installation ("internal" - is the name of a special limited, internal administration domain; this domain is different from Active Directory and exists based on a key in the Red Hat Enterprise Virtualization postgres database rather than as a directory service user on a directory server. There is only one admin@internal user in this internal domain).
