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:
|
||||
- CiscoUcs Establish a connection to a Cisco UCS fabric interconnect.
|
||||
- FTP Establish a connection to a FTP host.
|
||||
- NetAppFAS Establish a connection to a NetApp Clustered ONTAP filer.
|
||||
- VMware Establish a connection to a VMware vCenter or ESXi host.
|
||||
|
||||
.PARAMETER Credentials
|
||||
Use this parameter to bypass the stored credentials. Without this parameter Connect-To tries to read the
|
||||
needed credentials from the CredenialStore. 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.
