function Get-DbaUserPermission { <# .SYNOPSIS Displays detailed permissions information for the server and database roles and securables. .DESCRIPTION This command will display all server logins, server level securable, database logins and database securables. DISA STIG implementators will find this command useful as it uses Permissions.sql provided by DISA. Note that if you Ctrl-C out of this command and end it prematurely, it will leave behind a STIG schema in tempdb. .PARAMETER SqlInstance Allows you to specify a comma separated list of servers to query. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server .PARAMETER ExcludeSystemDatabase Allows you to suppress output on system databases .PARAMETER IncludePublicGuest Allows you to include output for public and guest grants. .PARAMETER IncludeSystemObjects Allows you to include output on sys schema objects. .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: Discovery, Permissions, Security Author: Brandon Abshire, netnerds.net Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaUserPermission .EXAMPLE Get-DbaUserPermission -SqlInstance sql2008, sqlserver2012 Check server and database permissions for servers sql2008 and sqlserver2012. .EXAMPLE Get-DbaUserPermission -SqlInstance sql2008 -Database TestDB Check server and database permissions on server sql2008 for only the TestDB database .EXAMPLE Get-DbaUserPermission -SqlInstance sql2008 -Database TestDB -IncludePublicGuest -IncludeSystemObjects Check server and database permissions on server sql2008 for only the TestDB database, including public and guest grants, and sys schema objects. #> [CmdletBinding()] Param ( [parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $True)] [Alias("ServerInstance", "SqlServer", "SqlServers")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [parameter(Position = 1, Mandatory = $false)] [switch]$ExcludeSystemDatabase, [switch]$IncludePublicGuest, [switch]$IncludeSystemObjects, [Alias('Silent')] [switch]$EnableException ) BEGIN { $sql = [System.IO.File]::ReadAllText("$script:PSModuleRoot\bin\stig.sql") $endSQL = " BEGIN TRY DROP FUNCTION STIG.server_effective_permissions END TRY BEGIN CATCH END CATCH;
