The users can login fine without including the trailing spaces, which is good, except we pass the user names into a third party support ticking application and when the names get passed all the spaces are there, and therefore the ticketing system does not work. (it cant match up the user names to its own database where the names are stored w/o the spaces). 

Is there anything i can do to get rid of trailing spaces in user names? From the user database even? I have tried using the module to reimport overwriting the users but it did not work.
