Synopsis

Checks database owners against a login to validate which databases do not match that owner.

Description

This function will check all databases on an instance against a SQL login to validate if that
login owns those databases or not. By default, the function will check against 'sa' for
ownership, but the user can pass a specific login if they use something else.

Optional Parameters

-SqlInstance

The target SQL Server instance or instances.

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Database

Specifies the database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed.

-ExcludeDatabase

Specifies the database(s) to exclude from processing. Options for this list are auto-populated from the server.

-TargetLogin

Specifies the login that you wish check for ownership. This defaults to 'sa' or the sysadmin name if sa was renamed. This must be a valid security principal which exists on the target server.

-InputObject

Enables piped input from Get-DbaDatabase.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
