<h2 id="synopsis">Synopsis</h2>
<p>Removes an SPN for a given service account in active directory and also removes delegation to the same SPN, if found</p>
<h2 id="description">Description</h2>
<p>This function will connect to Active Directory and search for an account. If the account is found, it will attempt to remove the specified SPN. Once the SPN is removed, the function will also remove delegation to that service.</p>
<p>In order to run this function, the credential you provide must have write access to Active Directory.</p>

<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
