nospace_user has removed from freeradius?

I am using the freeradius 2.1.3 in Slackware 12 I use simultaneous-use = 1 to block a second conection for same user, it work fine. But, if the user has a space after username, like "john ", the freeradius let it to connect. Looking for remove de spaces I found the nospace_user and nospace_pass, but appers it was removed in 1.0.5 version. And now? To remove spaces at the end of string its very important to utmp detect the username. Exist something to fix it?
