There are many examples online of how to access/use the SharePoint Client-Side Object Model with PowerShell. But of course, they don't seem to work for me. I seem to be having trouble accessing some of the credential code:

Windows PowerShell

PS C:\Scripts> [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")

GAC    Version        Location

PS C:\Scripts>
PS C:\Scripts> $webUrl = "https://abc.sharepoint.com>"
PS C:\Scripts> $username = "user3"
PS C:\Scripts> $password = "password"
PS C:\Scripts>
PS C:\Scripts> $ctx = new-object Microsoft.SharePoint.Client.ClientContext($webUrl)
PS C:\Scripts> $ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $password)
New-Object : Cannot find type Microsoft.SharePoint.Client.SharePointOnlineCredentials]: make sure the assembly containing this type is loaded.

    + CategoryInfo          : InvalidType: (:) [New-Object], PSArgumentException
    + FullyQualifiedErrorId : TypeNotFound,Microsoft.PowerShell.Commands.NewObjectCommand

I am attempting to access a SharePoint 2010 server that we maintain which requires logon authentication. Does anyone know what I am doing wrong?

SharePointOnlineCredentials is used for authenticating to Office365/ SharePoint 2013 Online services. If you don't have a hosted 2013 instance, it's not a surprise that PS can't find the type.

If you're working on a server you maintain in your own domain and you are using Windows Authentication, your context will pick up your existing security token.

If you're doing forms or claims based authentication, you'll have to tell your context: 

$ctx.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication;
$ctx.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo("domain\username", "password");

There's also a ClientContext.Credentials property if you need to enter alternate credentials.

This is working for me for SharePoint online

$siteUrl = “https://URL.sharepoint.com”
$password = Read-Host -Prompt "Enter password" -AsSecureString 
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl) 
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials("[email protected]", $password) 

$ctx.Credentials = $credentials

$web = $ctx.Web 
$ctx.Load($web) 
$ctx.ExecuteQuery()

I'm using the following successfully against a SharePoint 2013 on-premise installation. It is a little different to your example in that it prompts for credentials - but I think that's generally a better approach than entering the password in the script. 

$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($url)
$credentials = Get-Credential
$ctx.Credentials = $credentials
...

I am finally ready to try this again. I have updated my approach and am using some of this reply: PS C:\Scripts> AddCSOM PS C:\Scripts> $context = New-Object SharepointClient.PSClientContext("siteCollection") PS C:\Scripts> $credentials = Get-Credential # Here I was prompted for and supplied my domain\username and password PS C:\Scripts> $context.Credentials = $credentials PS C:\Scripts> $context.ExecuteQuery() Exception calling "ExecuteQuery" with "0" argument(s): "The remote server returned an error: (403) Forbidden." –  Michael Frederick Apr 1 at 20:52
