Description:
STC Logonids with PSWD-EXP set would continue to be used.
Solution:
Since a password would not be requested for an STC Logonid, ACF2 would not ask for a new password even if the PSWD-EXP is set.
An alternative command that could have been entered to change all Logonids EXCEPT STC Logonids is
ACF
SET LID
CHANGE IF(NOSTC) PSWD-EXP
