Authentication

The way that dscmd authenticates to the data source depends on the which set of options are passed to the specific command

if the --connectionString option is set​

When you set the --connectionString property none of the other --UserID --Password --Server or --Database options are used, the connection string parameter overrides all of these. So if the connection string has a User ID= or Password= options then those are used otherwise the identity running the dscmd process will be used

if the --UserID or --Password options are set​

Then these parameters are used to authenticate to the data source.

if the Authentication environment variables are set​

Then the values from those will be injected into the User ID= and Password= values in the connection string. There are 2 environment variables that dscmd is aware of

  • DSCMD_USER - this is passed as the User ID
  • DSCMD_PASSWORD - this is passed as the Password

Otherwise​

The identity running the dscmd process will be used for authentication. In the case of connections requiring an Entra ID a popup window will be displayed
