NAME Test-DbaConnectionAuthScheme



SYNOPSIS

Returns the transport protocol and authentication scheme of the connection. This is useful to determine if your

connection is using Kerberos.





SYNTAX

Test-DbaConnectionAuthScheme [-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>

[[-SqlCredential] <Pscredential>] [-Kerberos <Switch>] [-Ntlm <Switch>] [-EnableException <Switch>]

[<CommonParameters>]





DESCRIPTION

By default, this command will return the ConnectName, ServerName, Transport and AuthScheme of the current

connection.



ConnectName is the name you used to connect. ServerName is the name that the SQL Server reports as its

@@SERVERNAME which is used to register its SPN. If you were expecting a Kerberos connection and got NTLM instead,

ensure ConnectName and ServerName match.



If -Kerberos or -Ntlm is specified, the $true/$false results of the test will be returned. Returns $true or $false

by default for one server. Returns Server name and Results for more than one server.





PARAMETERS

-EnableException [<Switch>]

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.
