When first installing Datamaker, you login using the username 'administrator' and password 'marmite'. If for whatever reason this combination is no longer working, you will be able to reset it by running a query in the gtrep repository database. This document will explain how to reset the default administrator password for Datamaker. 


If you know for sure that you need to login with administrator/marmite (default when installing) and they are the correct username/password to use, but you are receiving an 'invalid username/password' error, you can user the resolution steps below. You may receive this error if at some point Datamaker was configured with Active Directory, or the password was changed by a past user. Since we need to go into the gtrep database and reset the password using a query, we recommend working with a DBA to execute this. 

For SQL and Oracle:
1. In the database management tool for your repository gtrep database, run the following query:

update gtrep_security_user set su_password='ZNC5eoXC858EiS8F+gVtt0fL-jn2mWYxIIGygx6gM+TV' where su_name='Administrator';

2. Launch Datamaker again and login with administrator/marmite. It should be successful.
