E-Notebook Enterprise: Staging Area is not available. Error code : 1326

We are having problem with SDM 

The error message: "Sorry, staging Area is not available. Error code : 1326"

You may need to:

1. Check if database users ELNSDMr and ELNSDMw are locked for any reason, and unlock them (how to: https://docs.oracle.com/en/database/oracle/oracle-database/12.2/axdbi/using-sql-plus-to-unlock-accounts-and-reset-passwords.html )
2. Re-crypt the DM_Account passwords. This is done by logging into the database as the SDM schema owner and running a statement like:

update dm_account set accountpassword = crypt('Password') where accountname = ‘AccountName’;

You will need to do that for both ELNSDMr (read) and ELNSDMw (write) accounts.
