Like I explained, NR==FNR is true while the first file on the command line is being read, and false for subsequent files. FNR is the line number within the current file and NR is the line number for all files so far. Obviously, unless the first file is empty, they will be different in the second and subsequent files.

login.krb5

LOGIN(8)                                                      System Manager's Manual                                                     LOGIN(8)

NAME

       login.krb5 - kerberos enhanced login program

SYNOPSIS

       login.krb5 [-p] [-fFe username] [-r | -k | -K | -h hostname]

DESCRIPTION

       login.krb5  is a modification of the BSD login program which is used for two functions.  It is the sub-process used by krlogind and telnetd
       to initiate a user session and it is a replacement for the command-line login program which, when invoked with a  password,  acquires  Ker-
       beros tickets for the user.

       login.krb5  will  prompt  for a username, or take one on the command line, as login.krb5 username and will then prompt for a password. This
       password will be used to acquire Kerberos Version 5 tickets (if possible.) It will also attempt to run aklog to  get  AFS  tokens  for  the
       user.  The  version 5 tickets will be tested against a local krb5.keytab if it is available, in order to verify the tickets, before letting
       the user in. However, if the password matches the entry in /etc/passwd the user will be unconditionally  allowed  (permitting  use  of  the
       machine in case of network failure.)

OPTIONS

       -p     preserve the current environment

       -r hostname
              pass hostname to rlogind.  Must be the last argument.

       -h hostname
              pass hostname to telnetd, etc.  Must be the last argument.

       -f name
              Perform pre-authenticated login, e.g., datakit, xterm, etc.; allows preauthenticated login as root.

       -F name
              Perform pre-authenticated login, e.g., datakit, xterm, etc.; allows preauthenticated login as root.

       -e name
              Perform pre-authenticated, encrypted login.  Must do term negotiation.

CONFIGURATION

       login.krb5  is  also  configured via krb5.conf using the login stanza. A collection of options dealing with initial authentication are pro-
       vided:

       krb5_get_tickets
              Use password to get V5 tickets. Default value true.

       krb_run_aklog
              Attempt to run aklog. Default value false.

       aklog_path
              Where to find it [not yet implemented.] Default value $(prefix)/bin/aklog.

       accept_passwd
              Don't accept plaintext passwords [not yet implemented]. Default value false.

DIAGNOSTICS

       All diagnostic messages are returned on the connection or tty associated with stderr.
