LOGIN_KERBEROS(8)	OpenBSD System Manager's Manual	     LOGIN_KERBEROS(8)

NAME
     login_krb5 - provide KerberosV authentication type

SYNOPSIS
     login_krb5 [-s service] [-v login=yes|no] [-v notickets=yes|no]
		[-v invokinguser=user] user [class]

DESCRIPTION
     The login_krb5 utility implements the KerberosV authentication mechanism.
     It is called by login(1), su(1), ftpd(8), and others to authenticate the
     user with KerberosV.

     The user argument is the user's name to be authenticated.

     The service argument specifies which protocol to use with the invoking
     program.  The allowed protocols are login, challenge, and response.  (The
     challenge protocol is silently ignored but will report success as
     KerberosV authentication is not challenge-response based).

     If invokinguser is set and the user argument is root, the principal
     invokinguser/root will be used for authentication.

     If the notickets argument is equal to ``no'', the default value, and the
     login argument is equal to ``yes'', then the ticket will be saved in a
     credentials cache.

     The class argument is ignored for compatibility with other login scripts.

     login_krb5 will prompt the user for a password and report back to the
     invoking program whether or not the authentication was successful.
