Validate Password Exit Program


  Required Parameter:

1 Validate password exit information Input Char(*)
2 Return indicator Output Char(1)

  QSYSINC Member Name: EVLDPWD1

  Exit Point Name: QIBM_QSY_VLD_PASSWRD

  Exit Point Format Name: VLDP0100

The Validate Password exit program is called when a Change Password (CHGPWD) command or Change Password (QSYCHGPW) API is executed. The exit program is called after the password composition rules have been checked.

The exit program examines the old and new password values for conformance with customer unique password composition rules. The exit program returns an indication whether the new password should be accepted or rejected. The exit point supports multiple exit programs. However, additional exit programs will not be called after receiving a indication that the new password should be rejected from one of the exit programs. (For information about adding an exit program to an exit point, see the Registration Facility part.)

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 should be rejected.

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.

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 should be rejected.

Note: The QPWDVLDPGM system value must be set to the value *REGFAC. If the QPWDVLDPGM system value contains any other value, the validate password exit programs will not be called.
