NAME

       siad_chg_finger, siad_chg_password, siad_chg_shell - Dependent SIA change routines (Security Integration Architecture)

LIBRARY

       Standard C library (libc.so and libc.a)

SYNOPSIS

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

       int siad_chg_finger(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

       int siad_chg_password(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

       int siad_chg_shell(
	    int (*collect)(),
	    char *username,
	    int argc,
	    char *argv[]);

PARAMETERS

       collect	 The  collect  parameter is a pointer to an SIA collection routine.  If this pointer is NULL, no collection is possible.  The col-
		 lect parameter should never be NULL.  This parameter is read only.

		 Further input on SIA collection routines is available from the interface specifications in /usr/include/{sia,siad}.h.

       username  The username parameter is used when a precollected username is available.  The username parameter either points  to  the  precol-
		 lected username or is set to NULL if no username exists.  This parameter is read only.

       argc	 The argc parameter is the number of arguments used when invoking the calling command or utility.  This parameter are read only.

       argv	 The argv parameter is the array of arguments used when invoking the calling command or utility.  The argv[0] variable must always
		 be set to the calling commands name.  This is used for logging or auditing of the password change function.

DESCRIPTION

   siad_chg_finger()
       This routine is called by sia_chg_finger() to accomplish processing associated with the chfn command with respect to  a	specific  security
       mechanism. Only one siad_chg_finger() routine is called. No sequencing of multiple security mechanisms is attempted.

   siad_chg_password()
       This routine is called by sia_chg_password() to invoke a specific mechanisms change password function. Only one siad_chg_password() routine
       is called.  This routine accomplishes the process commonly associated with the passwd command.  No sequencing of multiple  security  mecha-
       nisms is attempted.

   siad_chg_shell()
       This  routine  is  called by sia_chg_shell() to accomplish processing associated with the chsh  command with respect to a specific security
       mechanism. Only one siad_chg_shell() routine is	called.  No sequencing of multiple security mechanisms is attempted.

RETURN VALUES

       The siad_ses_*() routines return bitmapped values which indicate the following status:

       SIADSUCCESS Indicates unconditional success. All bits set to 0.

       SIADFAIL    Indicates conditional failure. Lowest bit set to 1.	If other security mechanism are in place, continue.

       SIADSTOP    Indicates unconditional failure. 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.

FILES

       /etc/passwd

       /etc/sia/matrix.conf
