A user can not change his password, after the password was reset with a TSS REPLACE(acid) PASSWORD(xxx).
With the NEWPW(MINDAYS=10) control option is set, the user tried to change the password the day it was replaced and received the following error occurs:
TSS7111E NEW PW (CHANGE) INVALID - CANNOT BE CHANGED YET
If NEWPW(MINDAYS=10) is set and the password is reset, then the user has to wait 10 days from when the password was reset, before the user can change the password again.
The administrator should do a:
TSS REPLACE(acid) PASS(xxxx,,EXP)
so the password is expired and let the user change the password. With the password expired, the user will be forced to change it at the next logon attempt.
