Steps to Reproduce:

2.# katello-configure --deployment=sam --user-name='root' --user-pass='redhat' --org-name='Red Hat Czech, s. r. o.'

Note: Log shows:

3. Attempt to use an Organization name with valid characters
# katello-configure --deployment=sam --user-name='root' --user-pass='redhat' --org-name='Red Hat Czech'

  Failed, please check [/var/log/katello/katello-configure/db_seed.log]
  Report errors using # katello-debug tool.

Note: This time log complaints that the user already exists


  
Actual results:
The user is stuck and katello-configure cannot resume even with a valid Organization name.



Expected results:
katello-configure should error out if the input parameters are invalid even before attempting to start the configuration
(or)
katello-configure should support an easy resume

Additional info:
As far as I know, I tried two workarounds for this issue and they worked:

WORKAROUND 1: (Do not use --user-name or --user-pass)
# katello-configure --deployment=sam --org-name='Red Hat Czech'
(Works fine - a new administrator user called 'admin' was also created.  I was able to log in both as 'root' or 'admin' user.  They both have administrator privileges)

WORKAROUND 2: (Using --reset-data=YES)
# katello-configure --reset-data=YES --deployment=sam --user-name='root' --user-pass='redhat' --org-name='Red Hat Czech'
(Works fine)
