Synopsis

Removes an SPN for a given service account in active directory and also removes delegation to the same SPN, if found

Description

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.

In order to run this function, the credential you provide must have write access to Active Directory.

Syntax

Remove-DbaSpn
    [-SPN] <String>
    [-ServiceAccount] <String>
    [[-Credential] <PSCredential>]
    [-EnableException]
    [-WhatIf]
    [-Confirm]
    [<CommonParameters>]

Example: 2
PS C:\> Remove-DbaSpn -SPN MSSQLSvc\SQLSERVERA.domain.something -ServiceAccount domain\account -EnableException

PS C:\> Remove-DbaSpn -SPN MSSQLSvc\SQLSERVERA.domain.something -ServiceAccount domain\account -Credential ad\sqldba

Required Parameters

-SPN

The SPN you want to remove

Alias RequiredSPN
Required True
Pipeline true (ByPropertyName)
Default Value
-ServiceAccount

The account you want the SPN remove from

Alias InstanceServiceAccount,AccountName
Required True
Pipeline true (ByPropertyName)
Default Value

Optional Parameters

-Credential

The credential you want to use to connect to Active Directory to make the changes

Alias
Required False
Pipeline true (ByPropertyName)
Default Value
-EnableException

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

Alias
Required False
Pipeline false
Default Value False
-WhatIf

Shows what would happen if the command was executed

Alias wi
Required False
Pipeline false
Default Value
-Confirm

Turns confirmations before changes on or off

Alias cf
Required False
Pipeline false
Default Value
