Local Authentication¶

The Data Catalog manages a local user account, protected by a password, that allows you to configure the following settings of the server:

• The Virtual DataPort servers listed in the login page.

• The connection settings used for all the queries executed on a Virtual DataPort server.

• The authentication configuration for enabling single sign-on with Kerberos.

• The external database where the Data Catalog stores its metadata.

It is helpful in situations where you need to change the server configuration, but you cannot connect to the Data Catalog because of an external service is down or the current authentication configuration is not correct.

To enter the Data Catalog with the local user account:

1. Navigate to the URL http://localhost:9090/denodo-data-catalog/#/web-local-login. You will see a login page like the one below.

2. Enter the password for the local user account. The default password is admin.

The authentication for the local user account is not delegated to an external system. It is the Data Catalog who validates that the password is correct. For security reasons, you should change the password of the local user account after your first access. To change this password, proceed as follows:

1. Log in the Data Catalog with the local user account.

2. Click the menu Administration > Change password.

3. Enter the current password and the new password twice.

As an alternative, use the script change_password_data_catalog.

To disable this local user account, follow these steps:

1. Open the file <DENODO_HOME>/conf/data-catalog/DataCatalogBackend.properties.

2. Change the value of the weblogin.enabled property as follows:

weblogin.enabled=false

disableLocalLogin=true
