On Windows XP - how do I use PowerShell background jobs which require windows authentication

Question

I'm trying to run some funtions in the background of a PoSh script. The job never completes, but works fine when called normall. I've narrowed the problem down to the following line:

This line works fine:

$ws = New-WebServiceProxy  "http://host/Service?wsdl" -UseDefaultCredential

but this line blocks forever

start-job { New-WebServiceProxy "same url" -UseDefaultCredential } `
 | wait-job | Receive-Job

Some details: the service is local, and requires windows authentication. Client is XP & server 2003.

Why? How do get it to work?

Answer 1

Got this to work. What OS are you running? XP or 2003 may be a problem.

start-job { 
        $zip = New-WebServiceProxy "http://www.webservicex.net/uszip.asmx?WSDL"  -UseDefaultCredential 
} | Wait-Job | Receive-Job

$zip | get-member -type method

Answer 2

I don't have any ASMX web services to test this against, but if you look at the help of Start-Job you'll see '-Authentication- and '-Credential'. The first specifies Default, Basic, Credssp, Digest, Kerberos, Negotiate, and NegotiateWithImplicitCredential. The second could be used to provide actual credentials to run the job.

Hope that helps.

You can use ConvertFrom-SecureString and ConvertTo-SecureString cmdlets

Once run

$securestring = read-host -assecurestring
convertfrom-securestring $securestring | out-file c:\securestring

it will create a secured file on disk after that you can use

$pass = Get-Content c:\securestring | convertto-securestring
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist “domain\administrator”,$pass

and

start-job { New-WebServiceProxy "same url" -Credential $cred } | wait-job | Receive-Job
