Hi, If i create a LOGIN based on a windows group it seems impossible to add it as 'USER' to a database because of the default_schema that is always used by the add-sqluser command. A Default schema can't be set for DBUSERS based on INSTANCE users based on windows groups. i'm downloading the source code now to see if i can adapt the cmdlet to my needs.

EDIT=> After removing the default_schema reference from the code completely, it works. I created a new function add-gsqluser

Add-SqlUser : Exception calling "Create" with "0" argument(s): "Create failed for User 'G.r-Server123_MgmtDb_db_ddladmin'. "
Microsoft.SqlServer.Management.Smo.FailedOperationException: Create failed for User 'G.R-srvbedi172_DemeMgmtDb_db_ddladmin'. ---> Microsoft.SqlServer.Manageme

This issue is an underlying SQL Server feautre. As you've noticed you cannot assign a default schema to a Windows group. See this connect item for more details:

Yes i know. I'm not pointing in that direction, i'm pointing to the fact that if a function is created to create db users, it should verify if the login specified is a group or not and then create it with or without default schema (default_schema = DBO for users / default_Schema is not parsed for user based on groups ) ? Now the function just checks if a default_schema is given or not. If not it passes DBO. It should not pass anything in case the instance login is an AD group. to my feeling, this is a bug.

For my issue, it's solved. Perhaps in a future release this can be caught?

anyway, great set of functions !
