function New-CredentialStoreItem { <# .SYNOPSIS Adds a credential store item containing host, user and password to the given store. .DESCRIPTION The credentials are stored without any relations to it's further use. If you need to change an existing item please use Set-CredentialStoreItem. You need to decide afterwards, whether to use the credential for a VIConnection, NetApp FAS or UCS Fabric Interconnect. .PARAMETER Path Define the store in which you would like to add a new item. .PARAMETER RemoteHost The identifier or rather name for the given credentials. .PARAMETER Identifier Provide a custom identifier to the given remote host key. This enables you to store multiple credentials for a single remote host entry. For example ad/sys1, ftp/sys1, mssql/sys1 .PARAMETER Credential You can provide credentials optionally as pre existing pscredential object. .INPUTS [None] .OUTPUTS [None] .EXAMPLE New-CredentialStoreItem -Path "C:\TMP\mystore.json" -RemoteHost "esx01.myside.local" .NOTES ``` File Name : New-CredentialStoreItem.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 = $true, ParameterSetName = "Private")] [ValidateNotNullOrEmpty()] [string]$RemoteHost, [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [Parameter(Mandatory = $false, ParameterSetName = "Private")] [ValidateNotNullOrEmpty()] [string]$Identifier, [Parameter(Mandatory = $false, ValueFromPipeline = $true)] [ValidateNotNullOrEmpty()] [PSCredential]$Credential, [Parameter(Mandatory = $true, ParameterSetName = "Shared")] [switch]$Shared, [Parameter(Mandatory = $false, ParameterSetName = "Shared")] [ValidateNotNullOrEmpty()] [string]$Path ) begin { # Set the CredentialStore for private, shared or custom mode.
