What problem/issue/behavior are you having trouble with? What do you expect to see?
Having whitespace at the beginning or end of a registry server address is hard to see and can cause unexpected and difficult to track errors when pulling images. I don't believe having whitespace at the beginning or end of passwords/registry server addresses is valid anywhere, and trimming whitespace is a fairly standard procedure in this kind of entry form, so the web console should not allow it/should trim it.

What is the business impact? Please also provide timeframe information.
Developer and customer hours are wasted when time is spent debugging this kind of issue, which is a scenario that should not be allowed in the first place.

Where are you experiencing the behavior? What environment?
