1. Change this file name to users_org.cnf(or some other name which must be different from the "users.cnf")
2. Restart the IS
3. IS will recreate the users.cnf file with the default users and the default password(Administrator/manage)
4. Now open the users.cnf file and copy the password(which is encoded)
5. Now replacing this value in the Administrator pwd. of file user_org.cnf, will make the Administrator password to default i.e "manage".
6. You have to delete the users.cnf and rename the users_org.cnf to users.cnf back again(so as to keep the entries of the other users intact)
