Individual permission error while entering username in Caps letter

Hi,

Do the following step for reproducing the issue:
1. Go to permissions and click on 'Edit permission'. Now enter the username in Individual users permission. say my username is: vtest .. But while entering in the box I entered as Vtest (V- capital) and clicked on the 'Add' button.
Note:- I have not choose user from 'Find group'.. I have directly added the username in the textbox.
2. Now click 'Save All'...
3. Now you will find that the User get's added to the individual list, but having no permission (check the attached image).
Now when you again clicked on Edit permission.. it shows the view permission selected, but No permission after saving it.

If you uncheck all the permissions .. then also the user is displaying in the list with no permission ( Actually it must get disapper from their)

Cause of error: (I find it)--
due to entering username in Capital letter (here is..V ), it must be entered as 'vtest'.

My query/issues are:-
1. If we are entering username in Capital then also it must take the correct user.
2. After removing the permission then it get disapper from the permission list... ( Now how can I remove it from my list.. I don't know.. ...
