What does arcot save in the attribute that is set for PasswdSvcUserAtt in the adaptershim.ini and how can that attribute value be translated so that it can be read by humans.
The value that is seen in the attribute for PasswdSvcUserAtt is epoch value and is a time stamp when the password was changed. Which means value is epoch and you can convert it on any time that can be read by humans. There are online converters that you can use.
