function New-DbaCredential { <# .SYNOPSIS Creates a new SQL Server credential .DESCRIPTION Creates a new credential .PARAMETER SqlInstance The target SQL Server(s) .PARAMETER SqlCredential Allows you to login to SQL Server using alternative credentials .PARAMETER Name The Credential name .PARAMETER Identity The Credential Identity .PARAMETER SecurePassword Secure string used to authenticate the Credential Identity .PARAMETER MappedClassType Sets the class associated with the credential. .PARAMETER ProviderName Sets the name of the provider .PARAMETER Force If credential exists, drop and recreate .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command .PARAMETER 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. .NOTES Tags: Certificate, Credential Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> New-DbaCredential -SqlInstance Server1 You will be prompted to securely enter your password, then a credential will be created in the master database on server1 if it does not exist. .EXAMPLE PS C:\> New-DbaCredential -SqlInstance Server1 -Confirm:$false Suppresses all prompts to install but prompts to securely enter your password and creates a credential on Server1. .EXAMPLE PS C:\> $params = @{ >>SqlInstance = "Server1" >>Name = "AzureBackupBlobStore" >>Identity = "https://<Azure Storage Account Name>.blob.core.windows.net/<Blob Container Name>" >>SecurePassword = (ConvertTo-SecureString '<Azure Storage Account Access Key>' -AsPlainText -Force) >>} PS C:\> New-DbaCredential @params Creates a credential, "AzureBackupBlobStore", on Server1 using the Access Keys for Backup To URL. Identity must be the full URI for the blob container that will be the backup target. The SecurePassword supplied is one of the two Access Keys for the Azure Storage Account. .EXAMPLE PS C:\> New-DbaCredential -SqlInstance Server1 -Name 'https://<Azure Storage Account Name>.blob.core.windows.net/<Blob Store Container Name>' -Identity 'SHARED ACCESS SIGNATURE' -SecurePassword (ConvertTo-SecureString '<Shared Access Token>' -AsPlainText -Force) Create a credential on Server1 using a SAS token for Backup To URL. Name has to be the full URI for the blob store container that will be the backup target. The SecurePassword will be the Share Access Token (SAS) and passed in as a SecureString. #> [CmdletBinding(SupportsShouldProcess)] #, ConfirmImpact = "High" param ( [parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [object[]]$Name = $Identity, [parameter(Mandatory)] [Alias("CredentialIdentity")] [string[]]$Identity, [Alias("Password")] [Security.SecureString]$SecurePassword, [ValidateSet('CryptographicProvider', 'None')] [string]$MappedClassType = "None", [string]$ProviderName, [switch]$Force, [switch]$EnableException ) begin { $mappedClass = switch ($MappedClassType) { "CryptographicProvider" { 1 } "None" { 0 } } } process { if (!$SecurePassword) { Read-Host -AsSecureString -Prompt "Enter the credential password" } foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } foreach ($cred in $Identity) { $currentCred = $server.Credentials[$Name] if ($currentCred) { if ($force) { Write-Message -Level Verbose -Message "Dropping credential $Name" $currentCred.Drop() } else { Stop-Function -Message "Credential exists and Force was not specified" -Target $Name -Continue } } if ($Pscmdlet.ShouldProcess($SqlInstance, "Creating credential for database '$cred' on $instance")) { try { $credential = New-Object Microsoft.SqlServer.Management.Smo.Credential -ArgumentList $server, $Name $credential.MappedClassType = $mappedClass $credential.ProviderName = $ProviderName $credential.Create($Identity, $SecurePassword) Add-Member -Force -InputObject $credential -MemberType NoteProperty -Name ComputerName -value $server.ComputerName Add-Member -Force -InputObject $credential -MemberType NoteProperty -Name InstanceName -value $server.ServiceName Add-Member -Force -InputObject $credential -MemberType NoteProperty -Name SqlInstance -value $server.DomainInstanceName Select-DefaultView -InputObject $credential -Property ComputerName, InstanceName, SqlInstance, Name, Identity, CreateDate, MappedClassType, ProviderName } catch { Stop-Function -Message "Failed to create credential in $cred on $instance.
