How to create a Web Application when SQL is running in SQL Authentication mode ?

Question

Hi,
I a have the following config:
SQL server 2012 with mixed authentication, running in the LAN
IIS server with SharePoint 2013 SP1, running in a DMZ --> SharePoint contacts the SQL server with a SQL login (not a Windows login, the required port has been opened in the FW)
SharePoint is working fine but when I want to create a new Web Application, I get an error: "Could not connect to MySQLServer\MySQLInstance,MyPortnumber using integrated security: Cannot
connect to database master at SQL server. The database might not exist, or the current user does not have permission to connect to it."
I think, since I use SQL authentification,  I have to use PowerShell. I found a script on the Internet but this script was not made to create a Web App which a SharePoint installed with SQL authentication.
Can you help to adapt the script ?

THE SCRIPT Documentation:
New-SPWebApplication -ApplicationPool <String> -Name <String> [-AdditionalClaimProvider <SPClaimProviderPipeBind[]>] [-AllowAnonymousAccess <SwitchParameter>] [-ApplicationPoolAccount <SPProcessAccountPipeBind>]
[-AssignmentCollection <SPAssignmentCollection>] [-AuthenticationMethod <String>] [-AuthenticationProvider <SPAuthenticationProviderPipeBind[]>] [-Confirm [<SwitchParameter>]] [-DatabaseCredentials <PSCredential>] [-DatabaseName
<String>] [-DatabaseServer <String>] [-HostHeader <String>] [-Path <String>] [-Port <UInt32>] [-SecureSocketsLayer <SwitchParameter>] [-ServiceApplicationProxyGroup <SPServiceApplicationProxyGroupPipeBind>] [-SignInRedirectProvider
<SPTrustedIdentityTokenIssuerPipeBind>] [-SignInRedirectURL <String>] [-Url <String>] [-WhatIf [<SwitchParameter> ]] [<CommonParameters>]
The Example:
$siteName = “PowerShell for SharePoint”
$port = 80
$hostHeader = “lab.ps4sp.com”
$url = “http://lab.ps4sp.com&#8221;
$appPoolName = “PS4SPAppPool”
$managedAccount = “PS4SPspservice”
$dbServer = “PS-SQL”
$dbName = “PS4SP_SP2010_LAB_ContentDB”
$allowAnonymous = $true
$authenticationMethod = “NTLM”
$ssl = $false
New-SPWebApplication -Name $siteName -Port $port -HostHeader $hostHeader -URL $url -ApplicationPool $appPoolName -ApplicationPoolAccount (Get-SPManagedAccount “$managedAccount”) -DatabaseName $dbName -DatabaseServer $dbServer -AllowAnonymousAccess: $allowAnonymous
-AuthenticationMethod $authenticationMethod -SecureSocketsLayer:$ssl

Hi Scott,
Based on your aticle, I changed my script by adding the credential, but I still have an error.
Il also put the SQL specific port in the $dbServer variable.
Any idea ?
MY SCRIPT:
$siteName = "TEST Site"
$port = 80
$hostHeader = "sharepoint.test.be"
$url = "http://sharepoint.test.be"
$appPoolName = "TestAppPool"
$managedAccount = "DISNET\administrator"
$authenticationMethod = "NTLM"
$dbServer = "DSPORT-SQL02\DSPORTPRDEXT,50123"
$dbName = "WSS_TEST_Content"
$dbServer_secPassword = ConvertTo-SecureString "MySQLPassword" -AsPlaintext -Force
$dbServer_Creds = New-Object System.Management.Automation.PsCredential "DMZSharePointLoginSQL", $dbServer_secPassword
New-SPWebApplication -Name $siteName -Port $port -HostHeader $hostHeader -URL $url -ApplicationPool $appPoolName -ApplicationPoolAccount (Get-SPManagedAccount "$managedAccount") -AuthenticationMethod $authenticationMethod -DatabaseName
$dbName -DatabaseServer $dbServer -DatabaseCredentials $dbServer_Creds
