function Connect-To { <# .SYNOPSIS Connects to the given host using the stored CredentialStoreItem. .DESCRIPTION Establish a connection to the selected host using a stored CredentialStoreItem. .PARAMETER RemoteHost Specify the host, for which you would like to change the credentials. .PARAMETER Identifier Defaults to "". Specify a string, which separates two CredentialStoreItems for the same hostname. .PARAMETER Type Specify the host type of the target. Currently implemented targets are: Possible connection values are: CiscoUcs, FTP, NetAppFAS, VMware, CisServer, ExchangeHTTP, ExchangeHTTPS, SCP. .PARAMETER Credentials Use this parameter to bypass the stored credentials. Without this parameter Connect-To tries to read the needed credentials from the CredentialStore. If you provide this parameter you skip this lookup behavior. So you can use it to enable credentials without preparing any user interaction. .PARAMETER Path Define a custom path to a shared CredentialStore. .PARAMETER Shared Switch to shared mode with this param. This enforces the command to work with a shared CredentialStore which can be decrypted across systems. .INPUTS [None] .OUTPUTS [None] .EXAMPLE Connect-To -RemoteHost "ucs.myside.local" -Type CiscoUcs .EXAMPLE Connect-To -RemoteHost "ftp.myside.local" -Type FTP .EXAMPLE Connect-To -RemoteHost "fas.myside.local" -Type NetAppFAS .EXAMPLE Connect-To -RemoteHost "esx01.myside.local" -Type VMware .EXAMPLE Connect-To -RemoteHost "vCenter.myside.local" -Type CisServer .EXAMPLE Connect-To -RemoteHost "exchange01.myside.local" -Type ExchangeHTTP .EXAMPLE Connect-To -RemoteHost "exchange01.myside.local" -Type ExchangeHTTPS .NOTES File Name : Connect-To.ps1 Author : Marco Blessing - marco.blessing@googlemail.com Requires : .LINK https://github.com/OCram85/PSCredentialStore #> [CmdletBinding(DefaultParameterSetName = "Private")] param( [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [Parameter(Mandatory = $true, ParameterSetName = "Private")] [string]$RemoteHost, [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [Parameter(Mandatory = $false, ParameterSetName = "Private")] [string]$Identifier, [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [Parameter(Mandatory = $true, ParameterSetName = "Private")] [ValidateSet( 'CiscoUcs', 'FTP', 'NetAppFAS', 'VMware', 'CisServer', 'ExchangeHTTP', 'ExchangeHTTPS', 'SCP' )] [string]$Type, [Parameter(Mandatory = $False, ParameterSetName = "Shared")] [Parameter(Mandatory = $False, ParameterSetName = "Private")] [PSCredential]$Credentials, [Parameter(Mandatory = $true, ParameterSetNAme = "Shared")] [switch]$Shared, [Parameter(Mandatory = $False, ParameterSetName = "Shared")] [ValidateNotNullOrEmpty()] [string]$Path, [Parameter(Mandatory = $False, ParameterSetName = "Private")] [Parameter(Mandatory = $False, ParameterSetName = "Shared")] [switch]$PassThru ) begin { # Set the CredentialStore for private, shared or custom mode.
