    Hi,

    in my service I have one box linux runing openldap with five thousand
    accounts. Many servers linux do authentication in this box and everything
    is fine. We also use box freebsd 4, however without this feature because
    not works nss_ldap in this version. Well, whith the begin of the 5.1, a could
    see this working (thanks Vidrine).

    My problem is size of username, that can be bigger than seventeen caracteres.
    The define MAXLOGNAME in /usr/include/sys/param.h and UT_NAMESIZE
    in /usr/include/utmp.h show me this.

    I think that change this value can resolv. After one cvsup of current, my login
    and syslogd were compiled again but not works. Then I did one attach with
    gdb in login and I watched that mistake was in setlogin(username) in the
    child process.

    If this is true, I need recompile the kernel and libc (make world)
    with the new values? What can I do in this case?

    ps. About 5.1-beta2, my console is full of warnings:
