FreeBSD: usernames longer than 16 chars

Question

Can someone give me the complete process to change FreeBSD from a 16 char max to 64 char max on unsername length?

Essentially this is to add some support for Virtualmin/Webmin.

Inspired from http://forums.freebsd.org/showthread.php?t=1447 I tried the following:

Changed in /usr/src/sys/sys/param.h

#define MAXLOGNAME      65              /* max login name length (incl. NUL) */

Changed in /usr/src/include/utmp.h

#define UT_NAMESIZE     64      /* see MAXLOGNAME in <sys/param.h> */

Ran

# cd /usr/src
# make buildworld

And now

# adduser

Still reports too long username!?

Install world:

# make installworld
