Solaris 10 username length warning removal

We are looking for a way to remove the warning that shows up when you login
or use sudo with a username that is longer than 9 characters, below is an
example of the warning:

WARNING: Username length for 'foobarfoobar' exceeds platform restriction of
maximum 9 characters.

I see in /usr/include/limits.h that I think we could change it, but not
sure all or even what I would need to recompile.

Any help?


Thanks,
Chris
