Open Stack

I have found a way to solve it and give access to users that have
passwords with spaces at the beginning/end. The issue (not an issue
per se, but it affects horizon [stein]) lies in django. Specifically
on 'django/forms/fields.py'

Horizon uses the fields and those by default remove spaces as stated,
what I did is the following:

On that file, the class CharField's constructor was removing
leading/trailing spaces:
Below is the diff between the original and the modified python script
(one line modified, strip=False)

 class CharField(Field):
-    def __init__(self, max_length=None, min_length=None, strip=True,
empty_value='', *args, **kwargs):
+    def __init__(self, max_length=None, min_length=None, strip=False,
empty_value='', *args, **kwargs):
         self.max_length = max_length
         self.min_length = min_length
         self.strip = strip

Now passwords are not altered by the underlying framework. Not sure
the effect of not removing trailing/leading spaces from the textfields
will have on the Horizon operations, though. Maybe horizon should
redefine that django class to avoid this behavior. I'm also open to
other solutions from the community. Have a great evening,


Thanks.
