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  Kerberos
       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	 pass‐
       word  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.)

       -r hostname

       -f name

	      allows preauthenticated login as root.

       -F name
