Buddypress integration problem

I have the simple LDAP login plugin up and running and working great in high security mode and creating wordpress user accounts for previously unregistered users. I was having a problem with integrating with buddypress however, as the user account was creating the user_nicename with a space between the first and second names, which broke the user profile page by creating an unlinkable url. I managed to get around it by changing the code as follows:

original:

if( is_array($userinfo) ) {
			$user_data['user_nicename'] 	= $userinfo['givenname'][0] . ' ' . $userinfo['sn'][0];
			$user_data['user_email'] 	= $userinfo['mail'][0];
			$user_data['display_name']	= $user_data['user_nicename']
			$user_data['first_name']	= $userinfo['givenname'][0];
			$user_data['last_name'] 	= $userinfo['sn'][0];
		}

hacked:

if( is_array($userinfo) ) {
			$user_data['user_nicename'] 	= $username;
			$user_data['user_email'] 	= $userinfo['mail'][0];
			$user_data['display_name']	= $userinfo['givenname'][0] . ' ' . $userinfo['sn'][0];
			$user_data['first_name']	= $userinfo['givenname'][0];
			$user_data['last_name'] 	= $userinfo['sn'][0];
		}
