Localy on my machine i mean.

Hi,

Welcome to the EPiServer community.

To get a good base knowledge on working with EPiServer I suggest that you read the admin and editor manuals found on

http://world.episerver.com/Documentation/Items/Manuals/EPiServer-CMS/Administrator-Manuals---EPiServer-CMS-6-R2-print/

and

http://world.episerver.com/Documentation/Items/Manuals/EPiServer-CMS/Editor-Manuals---EPiServer-CMS-6-R2-print/

Users are setup in EPiServer with the .net MemberShip and RoleProviders. You can read about it in the EPiServer Whitepapers

http://world.episerver.com/Documentation/Items/Tech-Notes/EPiServer-CMS-6/EPiServer-CMS-60/Authentication-and-Authorization/

A normal setup on a developer machine is that you use WindowsMembershipProvider and use your normal Windows account (which normally is an administrator)

I hope this gives you some assistance on getting EPiServer up and running on your machine.

Great, thank you!

Like Alf says, on developer machines you are typically logged in with a Windows account (with local administrator privileges, meaning it will be automatically be a member of the built-in Administrators group). You'll then use your Windows credentials to log into your site.

For Windows login to work you need to use either WindowsMembershipProvider/RoleProvider or MultiplexingMembershipProvider/RoleProvider.
You can find this in your web.config:

However, if you want to create or edit users you need to use Multiplexing as your Membership/Role Provider. (Because you can't add/edit Windows accounts from within EPiServer).

Oh, and if all login options fail, you can always "break into" your site by removing/commenting all occurances of " in your web.config, as described here: http://blog.fredrikhaglund.se/blog/2010/03/08/episerver-security-and-access-control-12/

That way you can go straight to /EPiServer (or whatever your UI path is) without authentication, and create/edit users in Admin mode, then put "deny users" back in your web.config.

Just don't ever do that on production environments!
