SqlCmd 1.5.0 Access Denied in Elevation mode against WID - Work fine with old SqlCmd 15 (SQL2019)

[ggbce]

I use SQLCMD since many years to launch scripts on Microsoft WSUS databases (WID) like backup, shrink, etc.

Sinc some years I used the SQLCMD from "SQL Command Line Utilities 15" (MsSqlCmdLnUtils64.msi) and I never had issue. Everything is working fine.

I decided to move with SqlCmd 1.5.0 (latest vesion) to be up-to-date, security fixes. But he didn't work.

Due to a WID database limitation where it's not work in network and need administrator elevation, with old SqlCmd.exe I work like that:

1- Open a Command Line in elevation mode
2- Go to the SqlCmd Binn folder (C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\170\Tools\Binn\SQLCMD.exe). Version 15.0.2000.5
3- Type the command line to run my action. In this sample I will run a T-SQL script to shrink the database:
sqlcmd -S np:\.\pipe\MICROSOFT##WID\tsql\query -i "C:\script\shrink.sql" -o "C:\Script\shrink.log"

The content of the shrink.sql is:
USE [SUSDB]
GO
DBCC SHRINKDATABASE(N'SUSDB')
GO
DBCC SHRINKFILE(N'SUSDB', 0, TRUNCATEONLY)
GO

4- Everything work fine ! The database and files are shrinked !!!

If I install SqlCmd 1.5.0, I run the same command line, The I got in the log file:
Access denied
Access denied

It seem SqlCmd 1.5.0 have difficulties to connect.

If you run the command with "--driver-logging-level 255" do we get more info on what is failing? (I don't have WID set up on my local machine)

The issue could be how sqlcmd or go-mssqldb converts . to localhost

ODBC passes the named pipe path verbatim to CreateFile, while Go sqlcmd passes \\localhost\pipe\microsoft##wid\tsql\query

I don't know why WID's instance would block it but SQL instances do not:

C:\git\go-sqlcmd\cmd\modern>modern -S np:\\.\pipe\sql\query -Q "select 1"
