Description of problem:
The issue is that, in setup-ds.pl when you enter a password(and say you made a
mistake) and you confirm with another password, you are always again prompted
for only the confirmation password.

Version-Release number of selected component (if applicable):
[root@test dirsrv]# rpm -qa | grep 389
389-ds-base-libs-1.3.5.10-1.el7.x86_64

How reproducible:
[root@test slapd-test]# setup-ds.pl
<snip>

Directory Manager DN [cn=Directory Manager]:
Password:
Password (confirm):
The passwords do not match.  Please try again.

Password (confirm):
The passwords do not match.  Please try again.

Password (confirm):

</snip>

eg. In the above, I have to set my instance password as test1234
password: tst1234
password (confirm): test1234

This gives an error "The passwords do not match.  Please try again.
and it again it ask for the password (confirm)
Password (confirm): " . But, this will never let me enter my expected password
afresh.

Expected results:
It should again ask for new password first and then the password again to
confirm.
Even IPA Server installer allows you to re-enter the original password if you
get a password mismatch.
