I am trying to script User Mapping for different Login accounts. I have scripted the creation of users and individual server roles, but I can't figure out how to set User Mapping with Powershell, I will also need to set the Database Role membership, in Particular, db_backupoperator
Anyone know how to do this with Powershell?
Supposing your login is created
## Creating database user and assigning database role
#get variables
$instanceName = "yourInstance"
$loginName = "testLogin"
$dbUserName = "testUserName"
$databasename = "tempdb"
$roleName = "db_backupoperator"
$server = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $instanceName
#add a database mapping
$database = $server.Databases[$databasename]
$login = $server.Logins[$loginName]
if ($database.Users[$dbUserName])
{
$database.Users[$dbUserName].Drop()
}
$dbUser = New-Object `
-TypeName Microsoft.SqlServer.Management.Smo.User `
-ArgumentList $database, $dbUserName
$dbUser.Login = $loginName
$dbUser.Create()
#assign database role for a new user
$dbrole = $database.Roles[$roleName]
$dbrole.AddMember($dbUserName)
$dbrole.Alter
dbUserName as the User, I want the login which in my case is a group to be the User...I will add the code in for what I have.
