function Get-DbaServerRoleMember { <# .SYNOPSIS Get members of server roles for each instance(s) of SQL Server. .DESCRIPTION The Get-DbaServerRoleMember returns connected SMO object for server roles for each instance(s) of SQL Server. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances. .PARAMETER SqlCredential Login to the target instance using alternate Windows or SQL Login Authentication. Accepts credential objects (Get-Credential). .PARAMETER ServerRole The role(s) to process. If unspecified, all roles will be processed. .PARAMETER ExcludeServerRole The role(s) to exclude. .PARAMETER Login The login(s) to process. If unspecified, all logins will be processed. .PARAMETER ExcludeFixedRole Filter the fixed server-level roles. Only applies to SQL Server 2017 that supports creation of server-level roles. .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: ServerRole, Security, Login Author: Klaas Vandenberghe (@PowerDBAKlaas) Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com - License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaServerRoleMember .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance localhost Returns all members of all server roles on the local default SQL Server instance .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance localhost, sql2016 Returns all members of all server roles on the local and sql2016 SQL Server instances .EXAMPLE PS C:\> $servers = Get-Content C:\servers.txt PS C:\> $servers | Get-DbaServerRoleMember Returns all members of all server roles for every server in C:\servers.txt .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance localhost -ServerRole 'sysadmin', 'dbcreator' Returns all members of the sysadmin or dbcreator roles on localhost. .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance localhost -ExcludeServerRole 'sysadmin' Returns all members of server-level roles other than sysadmin. .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance sql2017a -ExcludeFixedRole Returns all members of server-level role(s) that are not fixed roles on sql2017a instance. .EXAMPLE PS C:\> Get-DbaServerRoleMember -SqlInstance localhost -Login 'MyFriendlyDeveloper' Returns all server-level role(s) for the MyFriendlyDeveloper login on localhost. #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory, ValueFromPipeline)] [Alias('ServerInstance', 'SqlServer')] [DbaInstance[]]$SqlInstance, [Alias('Credential')] [PSCredential]$SqlCredential, [string[]]$ServerRole, [string[]]$ExcludeServerRole, [object[]]$Login, [switch]$ExcludeFixedRole, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Attempting to connect to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message 'Failure' -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $roles = $server.Roles if (Test-Bound -ParameterName 'Login') { $logins = Get-DbaLogin -SqlInstance $instance -Login $Login Write-Message -Level 'Verbose' -Message "Filtering by logins: $($logins -join ', ')" foreach ($l in $logins) { $loginRoles += $l.ListMembers() } $loginRoles = $loginRoles | Select-Object -Unique Write-Message -Level 'Verbose' -Message "Filtering by roles: $($loginRoles -join ', ')" $roles = $roles | Where-Object { $_.Name -in $loginRoles } } if (Test-Bound -ParameterName 'ServerRole') { $roles = $roles | Where-Object { $_.Name -in $ServerRole } } if (Test-Bound -ParameterName 'ExcludeServerRole') { $roles = $roles | Where-Object { $_.Name -notin $ExcludeServerRole } } if (Test-Bound -ParameterName 'ExcludeFixedRole') { $roles = $roles | Where-Object { $_.IsFixedRole -eq $false } } foreach ($role in $roles) { Write-Message -Level 'Verbose' -Message "Getting Server Role Members for $role on $instance" $members = $role.EnumMemberNames() Write-Message -Level 'Verbose' -Message "$role members: $($members -join ', ')" if (Test-Bound -ParameterName 'Login') { Write-Message -Level 'Verbose' -Message "Only returning results for $($logins.Name -join ', ')" $members = $members | Where-Object { $_ -in $logins.Name } } foreach ($member in $members) { $l = $server.Logins | Where-Object { $_.Name -eq $member } if ($l) { Add-Member -Force -InputObject $l -MemberType 'NoteProperty' -Name 'ComputerName' -Value $server.ComputerName Add-Member -Force -InputObject $l -MemberType 'NoteProperty' -Name 'InstanceName' -Value $server.ServiceName Add-Member -Force -InputObject $l -MemberType 'NoteProperty' -Name 'SqlInstance' -Value $server.DomainInstanceName Add-Member -Force -InputObject $l -MemberType 'NoteProperty' -Name 'Role' -Value $role Select-DefaultView -InputObject $l -Property 'ComputerName', 'InstanceName', 'SqlInstance', 'Role', 'Name' } } } } } } |
