KUSEROK(3)							    KUSEROK(3)

NAME
       kuserok - Kerberos version of ruserok

SYNOPSIS
       #include <kerberosIV/krb.h>

       kuserok(kdata, localuser)
       AUTH_DAT *auth_data;
       char   *localuser;

DESCRIPTION
       kuserok determines whether a Kerberos principal described by the struc‐
       ture auth_data is authorized to login as user  localuser	 according  to
       the authorization file ("~localuser/.klogin" by default).  It returns 0
       (zero) if authorized, 1 (one) if not authorized.

       If there is no account for localuser on the local  machine,  authoriza‐
       tion  is	 not granted.  If there is no authorization file, and the Ker‐
       beros principal described by auth_data translates to  localuser	(using
       krb_kntoln(3)),	authorization  is  granted.  If the authorization file
       can't be accessed, or the file is not owned by localuser, authorization
       is  denied.   Otherwise,	 the file is searched for a matching principal
       name, instance, and realm.  If  a  match	 is  found,  authorization  is
       granted, else authorization is denied.

       The file entries are in the format:
		 name.instance@realm
       with one entry per line.
