Managing Personas and Permissions

Disable Users

1. Click the Admin icon in the left sidebar, and then select the Users tab.

2. Select the user you would like to disable, and click the dropdown menu button in the upper right of the user details page.

3. Select Disable.

   

4. Click Disable in the confirmation dialog.

User Impersonation Use Cases

• The Project Path: In this case, the user wants multiple users to use the same dashboard and needs everyone to see the same data. An Immuta project is created and equalized. Then it is exposed to a PostgreSQL connection for projects; this gives the project a single connection for all the users to impersonate. A dashboard can then be created with the project's connection. After this creation multiple users can see the same data with the correct policies enforced.
• The Impersonation Path: This feature allows a user to identify themselves while watching a dashboard that is not their own. An identifier of the user requesting the data is presented with a special, sensitive access token. With this information the data on the dashboard can be personalized to the person viewing it, while still remaining a multi-user connection.

Configuration and Usage

1. Grant a selected Immuta user the IMPERSONATE_USER permission.
2. Use a tool capable of establishing a PostgreSQL-based SQL (see Analytic Tools for specifics on which tool to use) connection to connect to Immuta's Query Engine using the Immuta SQL credentials of the user with the IMPERSONATE_USER permission.

3. Enter into the Immuta Query Engine the iamid that is associated with the Immuta user account you want to impersonate.

   The iamid is the name of the Identity and Access Management (IAM) provider that the Immuta user you want to impersonate is associated with. The image below shows where the iamid can be located.

   

   For example, if using the iamid of "Okta" from above, the full SQL command would be

   SET immuta.impersonation_iamid = 'Okta';
   

   Note: The iamid is a case-sensitive value.

4. Enter into the Immuta Query Engine the userid that is associated with the Immuta user account you want to impersonate.

   The userid could be an email address (if using Immuta's built-in identity manager - or bim), or it could be a shortened form of the username like a sAMAccountName in Active Directory.

   For example, to specify a userid of jdoe, run

   SET immuta.impersonation_userid = 'jdoe';
   

   Note: The userid is a case-sensitive value.

5. In certain cases, it may be necessary to convert a shortened form of the username, like a sAMAccountName, to an email address in order to match it to an Immuta account. To handle this special case, Immuta has added a template capability such that the userid can be augmented by a specified template.

   For example, a sAMAccountName of jdoe can be converted into an email address at mycompany.com using a string template that substitutes the value of {userid} with the userid provided. The resulting value would be jdoe@mycompany.com.

   SET immuta.impersonation_userid_template = '{userid} @mycompany.com';
   

6. Now that your Immuta Query Engine session is configured to impersonate the desired Immuta user, as long as your session remains active, you queries will be executed as the impersonated user.

Notes and Caveats

• The Immuta user account with the IMPERSONATE_USER permission must have valid SQL credentials configured in order to conduct user impersonation via the Immuta Query Engine.
• Once impersonation is set, all subsequent SQL calls will be made as the impersonated user.
• User impersonation lasts the duration of the SQL connection. To stop impersonating a user simply close the connection.
• It is not possible to switch impersonated users within a single SQL connection. Each connection supports at most one impersonation setting. After user impersonation has been enabled, attempts to set a different user to impersonate will fail.

Migrate Users from Another IAM

1. Click the Admin icon in the left sidebar, and select the user from the Users tab.

2. Click the dropdown menu to the right of their name and select Migrate User.

   

3. Enter their username in the modal that appears and click Migrate User.

Remove Permission from User

1. Click the Admin icon in the left sidebar, and select the user from the Users tab.

2. Scroll to the Permissions section, and click the delete icon on the permission you want to remove.
