siad_chk_user(3)					      siad_chk_user(3)

NAME
       siad_chk_user - check user dependent routine for SIA (Security Integra‐
       tion Architecture)

SYNOPSIS
       #include <sia.h> #include <siad.h>

       int siad_chk_user(
	       char *loginname,
	       int chkflg );

LIBRARY
       Standard C library - libc.so and libc.a

PARAMETERS
       The loginname parameter specifies the login  name  of  the  user.  This
       parameter  is  read  only.  The chkflg parameter indicates which change
       request is being made.  See CHGFINGER, CHGPASSWD, CHGSHELL,  CHGENTITY,
       and CHGNEWVALUE in siad.h for more information.

DESCRIPTION
   siad_chk_user()
       This  routine  is  called  by the SIA  change information interfaces to
       determine if a particular mechanism  can	 change	 the  specified	 users
       password, finger, or shell.

RETURN VALUES
       The  siad_chk_user()  routine  returns a bitmapped value which indicate
       the following status: Indicates unconditional success. All bits set  to
       0.   Indicates conditional failure. Lowest bit set to 1. If other secu‐
       rity mechanism are in place, continue.  Indicates  unconditional	 fail‐
       ure. Do not continue. Second lowest bit set to 1.

ERRORS
       The  errno values are those returned from the dynamic loader interface,
       from the (siad_*) routines, or from  malloc.  Possible  errors  include
       resource constraints (no memory) and various authentication failures.
