Hi.
As noted in the ticket, there's a styling issue in the admin when password validators enabled, they are not properly aligned:

The root cause of this because validators help text is a list <ul> and it's placed inside of paragraph tag <p> which is not allowed:
<p class="help">{{ form.password2.help_text|safe }}</p>
Both of
Chrome and FF removes list out of <p> tag. Thus, I my initial solution was just to replace <p> tag with span.
However, how fairly mentioned Tim, this would be quite unsuitable for those, who already customized admin templates.
Another idea was to output password validation help text not in in <ul> list.
