# Script-level params: no Mandatory/ParameterSet attributes so dot-sourcing during Import-Module # does not prompt or throw. Validation happens inside the function's own param block. param( [string]$LoginsFolderPath, [string]$RolesFolderPath, [string]$Environment, [string]$SqlServer, [string]$EnvProfile, [Alias('Database')] [string]$OneDatabase, [switch]$ExportToExcel, [string]$ExportPath, [switch]$PassThru ) function Get-SqlAccessReport { <# .SYNOPSIS Reports who actually has access to a database, resolved all the way down to real principals. .DESCRIPTION Reads the declared access from Logins/*.json and Roles/*.json for the given environment - the same source of truth Sync-SqlUserAccess enforces onto SQL - and fully resolves it: - A role assigned to a login (built-in or a custom role from Roles/*.json) is expanded down through any nested role membership to its terminal, effective grants (see Expand-SqlRoleChain), while still recording the role name(s) that led there. - An `external` login is resolved through Entra ID (see Expand-EntraPrincipalChain): if it's a security group, membership is walked recursively - including nested groups - down to the actual Users, Managed Identities, and Service Principals inside it. A `sql` login is already a leaf and skips Entra resolution entirely. - A PIM-for-Groups eligible assignment nobody has activated yet is invisible to a plain group-membership lookup, which would otherwise silently report that branch as empty even though those people could self-elevate into real access at any time. This is checked separately (see Get-EntraGroupPimEligibleMembers) and surfaced via MembershipState - 'Active' for a real current member, 'Eligible' for someone who could activate into the access but hasn't. Once any hop in a chain is Eligible, every leaf below it is too, since access below an unactivated gate isn't real either. - The server's Microsoft Entra admin (see Get-SqlServerEntraAdmin) - an ARM-level property (Terraform azuread_administrator), not anything declared in JSON - has sysadmin-equivalent access to every database on the server. It's looked up via Get-AzSqlServer/ Get-AzSqlServerActiveDirectoryAdministrator (an ARM call, not a SQL connection) and resolved/expanded the same way as any other Entra login or group. These rows always come first in the output and cover every database the report already covers, regardless of -Database, since that access applies no matter which database is being looked at. This never queries the target SQL server itself - it reports the declared/enforced state from JSON plus the server's ARM-level Entra admin setting, not a live snapshot of SQL. If Sync-SqlUserAccess hasn't been run recently for this environment, this report may not reflect what's actually in SQL right now; run `Sync-SqlUserAccess -Verify` first if that's in doubt. Output is one row per (database, permission, resolved leaf principal), so the same person appears once per database they can reach through any path. .PARAMETER LoginsFolderPath Path to the folder containing per-login JSON files. .PARAMETER RolesFolderPath Optional. Path to the folder containing role definition JSON files (the same folder Sync-SqlRoles uses). Without it, custom roles are reported as-is instead of being expanded into their effective grants. With -EnvProfile, read from the profile's RolesFolderPath. .PARAMETER Environment The environment to match against "acceptedenvironments" in each JSON file (e.g. 'DEV', 'PROD'). .PARAMETER SqlServer The Azure SQL Server FQDN, used only to look up the server's Microsoft Entra admin via ARM (Get-AzSqlServer/Get-AzSqlServerActiveDirectoryAdministrator) - this report never connects to SQL itself. Matched by short server name against whatever Azure subscription is currently selected; silently skipped (no admin rows, no error) if not found there, which is the expected/correct outcome for a VM-hosted target (no such ARM concept exists for those). .PARAMETER EnvProfile Path to a JSON profile file containing LoginsFolderPath, SqlServer, Environment, and optional RolesFolderPath and LoginIgnoreList (same profile files Sync-SqlUserAccess uses). .PARAMETER OneDatabase Limits the report to a single database. Omit to report on every database declared in JSON. The server Entra admin's rows are still included for this one database, since that access isn't scoped by -Database at all. .PARAMETER ExportToExcel Writes the report to a formatted .xlsx (a title and generated-on date above the table, a light-blue-filled bold header row frozen while scrolling, autofilter) in addition to printing it to the console, then opens it. The ImportExcel module (not a hard dependency of this module - only needed when this switch is used) is installed automatically on first use if it isn't already present. .PARAMETER ExportPath Output path for -ExportToExcel. Defaults to <Desktop>\SQLAccessReport_<Environment>_(<Database>_)<yyyyMMdd>.xlsx - the Database segment only appears when -Database was specified. .PARAMETER PassThru Returns the flat report rows as objects, for further scripting/piping. .EXAMPLE Get-SqlAccessReport -EnvProfile .\Profiles\example.json .EXAMPLE Get-SqlAccessReport -EnvProfile .\Profiles\example.json -Database MyAppDb -ExportToExcel #> [CmdletBinding()] param( [Parameter(Mandatory, ParameterSetName = 'Direct')] [string]$LoginsFolderPath, [Parameter(ParameterSetName = 'Direct')] [string]$RolesFolderPath, [Parameter(Mandatory, ParameterSetName = 'Direct')] [string]$Environment, [Parameter(Mandatory, ParameterSetName = 'Direct')] [string]$SqlServer, [Parameter(Mandatory, ParameterSetName = 'Profile')] [string]$EnvProfile, [Parameter(Mandatory = $false)] [Alias('Database')] [string]$OneDatabase, [switch]$ExportToExcel, [string]$ExportPath, [switch]$PassThru ) # --- Startup banner --- Write-Host "Starting SQL Access Report`n" -ForegroundColor Green $loginIgnoreList = @() if ($PSCmdlet.ParameterSetName -eq 'Profile') { if (-not (Test-Path $EnvProfile)) { throw "Environment profile file not found: $EnvProfile" } $ep = Get-Content $EnvProfile -Raw | ConvertFrom-Json Write-Host "Using Environment Profile: $EnvProfile" -ForegroundColor Cyan Write-Host "Logins Folder Path: $($ep.LoginsFolderPath)" -ForegroundColor Cyan Write-Host "SQL Server: $($ep.SqlServer)" -ForegroundColor Cyan Write-Host "Environment: $($ep.Environment)" -ForegroundColor Cyan $profileDir = Split-Path -Parent (Resolve-Path $EnvProfile) $LoginsFolderPath = if ([System.IO.Path]::IsPathRooted($ep.LoginsFolderPath)) { $ep.LoginsFolderPath } else { Join-Path $profileDir $ep.LoginsFolderPath } if ($ep.RolesFolderPath) { $RolesFolderPath = if ([System.IO.Path]::IsPathRooted($ep.RolesFolderPath)) { $ep.RolesFolderPath } else { Join-Path $profileDir $ep.RolesFolderPath } } $Environment = $ep.Environment $SqlServer = $ep.SqlServer if ($ep.LoginIgnoreList) { $loginIgnoreList = $ep.LoginIgnoreList } } else { Write-Host "Logins Folder Path: $LoginsFolderPath" -ForegroundColor Cyan Write-Host "SQL Server: $SqlServer" -ForegroundColor Cyan Write-Host "Environment: $Environment" -ForegroundColor Cyan } if ($RolesFolderPath) { Write-Host "Roles Folder Path: $RolesFolderPath" -ForegroundColor Cyan } if ($OneDatabase) { Write-Host "Database (filtered): $OneDatabase" -ForegroundColor Cyan } Write-Host '' # --- Pre-flight: fail fast if -ExportToExcel can't be satisfied, before doing any of the # role/Entra expansion work below. --- if ($ExportToExcel) { Initialize-ImportExcelModule } # --- Load declared access from JSON (no SQL connection - see .DESCRIPTION) --- $allLogins = Import-LoginConfig -LoginsFolderPath $LoginsFolderPath -Environment $Environment -IgnoreList $loginIgnoreList $roleDefsByName = @{} if ($RolesFolderPath) { foreach ($roleDef in (Import-RoleConfig -RolesFolderPath $RolesFolderPath -Environment $Environment)) { $roleDefsByName[$roleDef.role] = $roleDef } } else { Write-Warning 'No RolesFolderPath given - custom roles are reported as-is, not expanded into their effective grants.' } $entraCache = @{} $rows = [System.Collections.Generic.List[PSCustomObject]]::new() $loginCount = @($allLogins).Count $loginIndex = 0 foreach ($login in $allLogins) { $loginIndex++ Write-Progress -Activity "Building SQL access report" -Status $login.login ` -PercentComplete ([Math]::Round($loginIndex / $loginCount * 100)) $dbsForLogin = if ($OneDatabase) { $login.databases | Where-Object { $_.database -eq $OneDatabase } } else { $login.databases } if (-not $dbsForLogin) { continue } # Resolved once per login, not once per database - the same login/group resolves to the # same leaf set everywhere it's granted access. $leaves = if ($login.type -eq 'external') { @(Expand-EntraPrincipalChain -PrincipalName $login.login -Cache $entraCache) } else { # SQL-authentication logins aren't PIM-gated - always a real, active login. @([PSCustomObject]@{ GroupChain = '';
