I am upgrading my site to the official release 4.0.  I've updated everything under _EmptyProject, re-compiled my custom controls, then I got this error:

Server Error in '/' Application.

Parameter name: windowsIdentity.Name

[ArgumentException: Invalid full name format.

I've created a new project by the official release on my local workstation, and copied over all custom changes from the old site, pointed to the same database, and it works fine on my local machine.

When I publish the website to our server (Windows 2003 Service Pack 2), the error occurs again.  The server is good to run previous version Sitefinity 4 sites, only failed to run the official release.

Also I cannot install Sitefinity_4.0.1098.0.msi on that server, it says 'you must install a Windows service pack that contains a newer version of the Windows Installer service'.

Hi MJia,

1. What are the steps for reproducing this issue? Do you use windows authentication ?

2.Also I cannot install Sitefinity_4.0.1098.0.msi on that server, it says 'you must install a Windows service pack that contains a newer version of the Windows Installer service'.

You should upgrade your windows installer.

All the best,

Hi  MJia, Ivan,

I also faced the same problem on windows 2003 server and managed to solve it by setting 

"<

authentication mode="None"/>" in web.config

I am getting this message when following the instructions for "Enabling Windows Authentication to automatically access Sitefinity backend"

Invalid full name format.
Parameter name: windowsIdentity.Name

I have setup my LDap connection and have enabled it following the directions. Have changed the web.config and set authentication="Windows".  I can see list of LDap users if I login using Forms auth and go to users admin page. Please advise.

Hi Jeremy,

What version of Sitefinity are you using? SF 4.0 does not support correctly Windows Authentication. It has been fixed in the Q1 4.1 version.

Hi, can anyone advise on how to get over this error? I'm getting exactly the same error after following these instructions:

www.sitefinity.com/.../upgrading-sitefinity-projects.aspx

to upgrade a 4.0 sitefinity project to 4.1. I got it in the project manager fine, hit upgrade, seemed to go up to 100% with no problems. I can build my solution too no errors. But on browsing the site I get this. I've checked and The data config has the same db connection string as the 4.0 version. What does this error mean?

Server Error in '/xxx' Application.

Hi ,

We thrown this error Invalid full name format.", "windowsIdentity.Name" when the windowsIdentity.Name is not in format Domain\USER. I am not able to replicate this issue locally with LDAP and Windows authentication. Can you check what the the identity name?

System.Web.HttpContext.Current.User.Identity.Name

also

Windows Authentication should be set to on
Site/Sitefinity/Services - Windows Authentication should be off and Anonymous Authentication should be on


Kind regards,

Hi Jeremy,

I have the exact problem.  Have you found the fix yet?  I would imagine there are many people having this same problem.  Windows authetication or Active Directory integration to any app is a common requirement for most of the organizations.  There is seemed to be lack of support from Telerik for this area. 

This document -- Enabling Windows Authentication to automatically access Sitefinity backend
http://www.sitefinity.com/documentation/installation-and-administration-guide/system-settings/enabling-windows-authentication.aspx -- is not working.

I got the LDAP connection, membership provider, and roles (groups) working fine.  Before inserting "<authentication mode="Windows"/>" as the instruction #10 in the article, I login as admin with the default provider, and able to see my Active Directory users and groups.  This part is working.  But, after adding "<authentication mode="Windows"/>" to the web.config, restarted the IIS 7, I got the error:

"

Invalid full name format.
Parameter name: windowsIdentity.Name

Thanks,

Norman

Hi Ivan,

On your June 9th post, "We thrown this error Invalid full name format.", "windowsIdentity.Name" when the windowsIdentity.Name is not in format Domain\USER", can you elaborate this?  And also where can I find the identity name -- System.Web.HttpContext.Current.User.Identity.Name.

Thanks,

Norman

Hi Norman,

Please take a look at this MSDN article.
