In researching this scenario, all I could find was a suggestion that you contact Microstrategy, send them your metadata DB and ask them for the password.
This CAN'T be the only way.
Is there no way to simply reset the password in some fashion? Looking at the DSSMDUSRACCT table in the metadata DB, this appears to hold microstrategy (at first glance anyway) a hashed/encrypted password, but I don't believe this is correct, as every entry for every account is the same in the PASSWD field.
Can someone suggest an alternative beyond sending a database to Microstrategy?
