function Invoke-LdifFile
{
    <#
        .SYNOPSIS
            Invokes a LDIF file against a target server / forest.
         
        .DESCRIPTION
            Invokes a LDIF file against a target server / forest.
            Note: This command assumes schema updates executed against the schema master (and will automatically switch to target that server).
            LDIF files are not technically constrained to performing schema updates however.
            Thus this function is not suitable to performing domain NC changes in a subdomain.
         
        .PARAMETER Path
            Path to the ldif file to import
         
        .PARAMETER Server
            The server / domain to work with.
         
        .PARAMETER Credential
            The credentials to use for this operation.
 
        .PARAMETER Confirm
            If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
         
        .PARAMETER WhatIf
            If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
         
        .EXAMPLE
            PS C:\> Invoke-LdifFile -Path .\schema.ldif
 
            Imports the schema.ldif file into the current forest's schema.
