<p>The Check Password exit program is called when a
|
||
|
|
Create User Profile (CRTUSRPRF) command,
|
||
|
|
Change User Profile (CHGUSRPRF) command,
|
||
|
|
Change Password (CHGPWD)
|
||
|
|
command, or Change Password (QSYCHGPW) API is used to
|
||
|
|
set or change the password associated with a
|
||
|
|
user profile. The exit program is
|
||
|
|
called after the system value based
|
||
|
|
password composition rules have been successfully checked.</p>
|
||
|
|
|
||
|
|
<p><strong>Note:</strong> The Limit Password Character Positions
|
||
|
|
(QPWDPOSDIF) system value based composition rule is not checked
|
||
|
|
before calling the exit program
|
||
|
|
because the old password value is not available through all of
|
||
|
|
the interfaces that can set or change the password.</p>
|
||
|
|
|
||
|
|
<p>The exit program can examine the new password value for conformance
|
||
|
|
with customer unique password composition rules. The exit program returns an
|
||
|
|
indication whether the new password conforms to the customer's
|
||
|
|
password rules. This indication will be used so that the security
|
||
|
|
audit journal can record whether the
|
||
|
|
changed password conforms to the password composition rules. However,
|
||
|
|
the password will be changed regardless of whether the exit program
|
||
|
|
returns an indication that the password does not conform to the
|
||
|
|
customer's password rules.</p>
|
||
|
|
|
||
|
|
<p>The exit
|
||
|
|
point supports multiple exit programs. However, additional exit programs will
|
||
|
|
not be called after receiving an indication that the new password does not
|
||
|
|
conform from one of the exit programs. (For information about adding an exit
|
||
|
|
program to an exit point, see the Registration Facility part.)</p>
|
||
|
|
|
||
|
|
<p>Any escape message received from an exit program or encountered while trying
|
||
|
|
to call an exit program, will be treated as an indication that the new password
|
||
|
|
does not conform to the customer's password rules.</p>
|
||
|
|
|
||
|
|
<p>The specified exit program must exist in the system auxiliary storage pool
|
||
|
|
(ASP) or one of the basic user ASPs at the time it is added to the registration
|
||
|
|
facility. If the program does not exist, the request to add the exit program
|
||
|
|
will be rejected.</p>
|
||
|
|
|
||
|
|
<p>The exit program must exist in the system ASP or one of the basic user ASPs
|
||
|
|
at the time the exit point attempts to locate the exit program. If the
|
||
|
|
specified exit program does not exist in the system ASP or one of the basic
|
||
|
|
user ASPs, the condition will be treated as an indication that the new password
|
||
|
|
does not conform to the customer's password rules.</p>
|
||
|
|
|
||
|
|
<p>This exit point is very similar to the
|
||
|
|
QIBM_QSY_VLD_PASSWRD exit point. The key differences between these two
|
||
|
|
exit points are:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>This exit point is called after the password has been changed while
|
||
|
|
the QIBM_QSY_VLD_PASSWRD exit is called before the password is changed.</li>
|
||
|
|
|
||
|
|
<li>The returned indicator for this exit program does not effect the
|
||
|
|
password change while the return indicator from the QIBM_QSY_VLD_PASSWRD
|
||
|
|
exit does effect whether the password is changed.
|
||
|
|
</li>
|
||
|
|
|
||
|
|
<li>This exit point is called for passwords set by the CRTUSRPRF and
|
||
|
|
CHGUSRPRF comands while the QIBM_QSY_VLD_PASSWRD is not called for
|
||
|
|
either of these commands.</li>
|
||
|
|
|
||
|
|
<li>All cases where the QIBM_QSY_VLD_PASSWRD exit is called
|
||
|
|
(and all successful indications were returned) will also call this exit.
|
||
|
|
However, the reverse is not true.
|
||
|
|
</li>

||
|

|
||
|
