Title: #824: ca-add: validate Subject DN name attributes
felipevolpone commented:
"""
I tested and it fixes the error.
I'm not sure if it's relevant, but maybe the unrecognized attributes could be
printed as the user wrote them.
This:
```ipa: ERROR: invalid 'Subject DN': Unrecognized attributes: dn```
Could be:
```ipa: ERROR: invalid 'Subject DN': Unrecognized attributes: DN```
Good to go.
