I was able to set new admin account with password "admin".
Login to mysql:
mysql> use ocsweb;
mysql> INSERT INTO `operators` (`ID`, `FIRSTNAME`, `LASTNAME`, `PASSWD`, `ACCESSLVL`, `COMMENTS`, `NEW_ACCESSLVL`, `EMAIL`, `USER_GROUP`) VALUES ("admin", "name", "surname", `21232f297a57a5a743894a0e4a801fc3`, 1, "Default administrator account", "sadmin", "email@email.com", "");
