I have an administator, which also is Farm Administrator in my Sharepoint environment. It is synced via UPSA and have all the properties I need do display content the right way. However - when I check the admin user in code behind it gets magically transferred to be SHAREPOINT\system instead of DOMAIN\Administrator... why is that?

Code behind:

    SPWeb currentWeb = SPContext.Current.Web;
    SPUser currentUser = currentWeb.CurrentUser;
    // currentUser is now SHAREPOINT\System

The Code behind is in a regular WebControlCode. Regular non-admin users get the correct currentUser attribute.

where is this code-behind? – TZHX Nov 28 '12 at 13:36
In our own developed sharepoint solution - called MyDepartment.cs. It's there to add a link to "My Department" through a user property: Department - to link correct. – Benny Skogberg Nov 28 '12 at 13:38
sorry, what I mean is, when it runs on the server, what is it running as? A regular web part? A sandboxed web part? Part of a timer job? – TZHX Nov 28 '12 at 13:39
I am taking a stab in the dark here but.. I presume it is because the code you are running is in SPSecurity.RunWithElevatedPrivileges? When running with this, the user becomes SHAREPOINT\System. – Hugh Wood Nov 28 '12 at 13:40
If you're not using RunWithElevatedPrivileges, does this user have a web application user policy set to "Account operates as System"? While I'm not 100% sure which takes precedence, I'd assume a user policy may supersede the user where system accounts are concerned. – webdes03 Nov 28 '12 at 14:33

Use something like this -

private SPUser GetCurrentUser()
    if (SPContext.Current.Web.CurrentUser.LoginName.Equals("SHAREPOINT\\system"))     
        return SPContext.Current.Web.SiteUsers[HttpContext.Current.User.Identity.Name];     

    return SPContext.Current.Web.CurrentUser;

and then use it in your code -

SPUser currentUser = GetCurrentUser();

If you are unsure about SPContext.Current.Web you may pass the SPWeb object as paramater

Hope this helps :)

if I change CurrentUser.ToString() to CurrentUser.LoginName it works like a charm! Thanx for your answer! – Benny Skogberg Nov 28 '12 at 14:49
