Premature expiry of user password
If the password of a user expires prematurely, the reason might be because of timezone and daylight saving.
Comparisons pertaining to password policy, such as validation of
maximum age of password (pwdMaxAge), are done in
Coordinated Universal Time. However, in geographical areas that follow
daylight saving, the password might expire prematurely or later than
due time. Premature expiry happens because the timestamps are not
monitored in Coordinated Universal Time. Users must convert the time
in their timezone to Coordinated Universal Time. Then, if they do
password expiry calculations, the password would expire at the expected
time that was set.
