Description of problem:

in response to running rhevm-manage-domains for a domain with missing SRV record,
like in bug 757519, a password is asked. There is no sense in asking for password in such case.

Version-Release number of selected component (if applicable):
SI22.1

How reproducible:
always

rhevm console log:

[root@lilach-rhel ~]# rhevm-manage-domains -action=add -domain=dc1.forest2008.qa.lab.tlv.redhat.com -user=vdcadmin -provider=ActiveDirectory -interactive
Enter password:
