When trying to implement the Unlock user, User's password last change time, the following error message is displayed:
dxmodify -h HOSTNAME -p PORT -D "cn=myuser,ou=example,dc=com" -w
dn: uid=myuser,ou=example,dc=com
changetype: modify
add: dxPwdLastChange
dxPwdLastChange: 20201007085640.941Z
modifying entry uid=myuser,ou=example,dc=com
ldap_modify: Constraint violation (19)
additional info: Cannot modify no-user-modification attributes

The dxPwdLastChange is an operational attribute is not supposed to be manipulated manually
This is working as designed, no one is supposed to manipulate any operational attributes manually.
