How to Pass password to Run as a Network Account in powershell

Question

Hello,
I ve been asked to raise this as a new topic as given in the link. The response also says that it is not possible to pass the password of a network account in powershell. How else can I implement the requirement?
http://social.technet.microsoft.com/Forums/windowsserver/en-US/41a4ba3d-93fd-485b-be22-c877afff1bd8/how-to-run-a-powershell-script-in-admin-account?forum=ITCG&prof=required
My requirement is that, I am need to run the powershell script via a network account. The powershell is called via a script on an ETL tool. When I ask it to print the output of the below command, the output says " Enter
the password of domain\username:". 
PS > runas
/user:{domain}\{username} powershell -file {nameOfPowershellScript.ps1}
Hence I had to modify the code to pass the password also in the same command. I am new to powershell scripting and the below command doesn't work.
Please suggest the appropriate way to pass the password of the network account.
 Referred to a link http://technet.microsoft.com/en-us/magazine/ff714574.aspx. 
$password = Get-Content c:\temp\password.txt | ConvertTo-SecureString 
$credential = New-Object System.Management.Automation.PSCredential
"CachedUser",$password 
PS > runas
/user:{domain}\{username} powershell -file {nameOfPowershellScript.ps1}
PS >$credential.Password | ConvertFrom-SecureString | Set-Content
c:\temp\password.txt

Thanks for the pointer. Question that I have is I am referencing sqljdbc4.jar in my application, which in turn using sqljdbc_auth.dll.
Which one should i refernce through <nativelib>. Is it sqljdbc4.jar or sqljdbc_auth.dll.
have added the following line to the .jnlp.
<nativelib href="sqljdbc4.jar"/>
But still it is complaining on sqljdbc_audth.dll. If it is sqljdbc_auth.dll, can I use <nativelib> to pass it.
In that case does it need to be signed?. If so,
Is it possible to sign .dll using 'jarsigner'?.
