Thsi post will explain how to change the activation period for new users
For security purposes, new users have a seven day activation period. After that seven day period they no longer can activate their account. The following steps will explain how to change that setting.
Open C:\Program Files\Sisense\PrismWeb\vnext\src\features\users\users.factory.js
On line 119, change the 7 to the time activation time limit you need:
expirationDate.setDate(expirationDate.getDate() + 7);
30 day expiration:
expirationDate.setDate(expirationDate.getDate() + 30);
Perform an IIS reset by opening the CMD (run as administrator), typing 'iisreset' and hit enter.
Your user now has 30 days to activate their account.
Please note that this change will be overwritten when an upgrade is performed.
