username length?

[Troy]

  Ok, Im stuck on this one and Im sure its something Im missing
somewhere..

Im running Owl aka Openwall linux.  Its core design is based on security
for ISP like environments.  Now, here is the problem.  Almost every dist
of linux I have ever used supports usernames longer then 8 characters, but
Owl does not.  Does anyone know what controls this, and where a conf file
might be found in order to chnage it to accept say, 9 character usernmes?

Thanks
