Forum: ASP.NET | Thema: ASP.net Forms Authentication | Von: G. Guest ( 17.01.2005 09:45)

Ich mache eine Authentifizierung über Form Auth.

Ich habe folgende Verzeichnisstruktur

Im Webroot liegen meine ASPX Dateien und folgende web.config
-----------------------------------------------------------------------------------
<authentication mode="Forms" >
<forms name=".ASPXAUTH" loginUrl="login.aspx" protection="All" timeout="30" path="/">
</forms>
</authentication>
<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->

<authorization>

<deny users="?" />
<allow users="*" /> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]"
roles="[comma separated list of roles]"/>
-->
</authorization>

aber das anmelden funzt nicht, ich werde nicht weitergeleitet. Stimmt da was mit der Datenbankverbindung nicht?
Wo geb ich den Namen für die Datenbank an, oder reicht eh nur der Tabellenname?
Ich verwende Windows Server 2003 und Sql Server 2000.
Kann mir jemand helfen?

liebe Grüße,
Andrea
