Question

I’m trying to get currently user credentials with a windows service in Windows 7.

When I run the code below on DEBUG mode (notice that, when I run this on DEBUG mode, the winservice runs on my User instead of LocalSystem), there is no problem. However, when the WinService runs on LocalSystem account on the machine I cannot get current user from active directory when I run the codes as “Released” (not debug) and as Windows Service?

using (DirectoryEntry de = new DirectoryEntry("LDAP://" + DomainName))
{
    using (DirectorySearcher adSearch = new DirectorySearcher(de))
    {
        adSearch.Filter = "(sAMAccountName=" + Environment.UserName + ")";
        SearchResult adSearchResult = adSearch.FindOne();

        UserInternalEmail = GetProperty(adSearchResult, "mail");
    }
}

Thanks in advance,

LocalSystem has no rights outside the local system, so it is pretty clear the AD/LDAP is going to reject it’s query. Just run the service under a AD/LDAP/domain account.
