• Credentials are objects that include the specification of a user account and password that can be used for authenticattion:
  • HTTP Authentication with a JobScheduler Master.
  • HTTP Authentication with a Proxy.
• Credentials objects can be created once and can be re-used:
  • Credentials can be created within a PowerShell session. The PowerShell built-in Get-Credential cmdlet can be used to specify credentials on the fly, e.g. prompting the user for input of the user account and password.
  • Credentials can be created outside of a PowerShell session and can be used in a PowerShell session. The Get-JobSchedulerSystemCredentials cmdlet can be used to retrieve an existing credentials object for authentification with the JobScheduler Master.

...

Using the target name login_as_ap from the above example allows the user who owns this credential to retrieve the credentials object.

• The Get-JobSchedulerSystemCredentials cmdlet accepts the target name of a system credentials object that is owned by the current user. This cmdlet returns a system credentials object.
• The Set-JobSchedulerCredentials cmdlet expects a PowerShell credentials object, that is used for authentication when accessing the JobScheduler Master.
• A conversion of system and PowerShell objects is required that can be achieved e.g. like this:

...

Explicit credentials can be specified with the Set-JobSchedulerCredentials cmdlet like this:

Set-JobSchedulerCredentials -Credentials $credentials

...

Explicit credentials can be specified on-the-fly with the Set-JobSchedulerCredentials cmdlet like this:

Set-JobSchedulerCredentials -AskForCredentials

...

• The cmdlet will prompt for input of the user account and password that are used for authentication with a proxy server.

Specifying credentials with the Web Service URL

Explicit credentials can be specified on-the-fly with the Use-JobSchedulerWebService cmdlet -Url parametewr like this:

Use-JobSchedulerWebService -Url http://root:root@localhost:4446 -Id scheduler111

Explanations

• The user account and password separated by a colon are preceeding the hostname and are separated by a @ character from the hostname. 
• Specifying credentials like this is considered insecure. 

Using the PowerShell profile to apply credentials

• Credentials can be added to the JobScheduler CLI by a PowerShell profile.  Typically the profile is stored with a file Microsoft.PowerShell_profile.ps1.
  • A number of locations are available for profiles. 
  • Check the value of the $Profile built-in variable for the currently active locations of your profile.
• You can copy & paste the above example for use of the Get-JobSchedulerSystemCredentials cmdlet to your PowerShell profile. This allows to automatically use the specified credentials for the JobScheduler Master.
