Deep Diving with Cross Forest, Multi Forest Configuration and Additional Info

From Joel Oleson’s Blog URL: http://blogs.msdn.com/joelo/archive/2007/03/08/cross-forest-multi-forest-configuration-additional-info.aspx:

Background
The people picker works in cross domain or cross forest environment. It works in both-way trust and one-way trust environment.
Out of the box, if the admin does not do any configuration, the people picker will issue queries to all two-way trusted domains and two-way trusted forests to search people & groups.
The people picker uses the application pool account to search the target domains and forests. If the application pool account does not have permission to the target domains or forests, or the admin want to use different account to search the target domains or forests, the admin could should use
How to Configure
Don’t forget to run stsadm.exe –o setapppassword –password on all machines in the farm where SharePoint is installed

2. Run on one WFE
stsadm.exe -o setproperty -url ...

What we have found:

Example of command:

stsadm.exe -o setproperty -url “http://MYSHAREPOINTSITE:21212″ -pn “peoplepicker-searchadforests” -pv “domain:mydomain.something.com,USERNAME,PASSWORD”

1. http://MYSHAREPOINTSITE:21212 = Your sharepoint site URL

2. mydomain.something.com = your domain, you can also use forest:BLAHBLAH

3. USERNAME = your username you want to use to connect to the domain/forest

4. PASSWORD = Password for the username you want to use to connect to the domain/forest

Errors you May Encounter:

Error 1:

Command line error.
Usage:
stsadm.exe -o [ ]

Solution:
Make sure you use quotes around peoplepicker-searchforests…. in the example text we use quotes around everything.

Example = -pn “peoplepicker-searchadforests”

Error 2:

The Web application at http://MYSHAREPOINTSITE:21212 could not be found. Verify
that you have typed the URL correctly. If the URL should be serving existing co
ntent, the system administrator may need to add a new request URL mapping to the
intended application.

Solution:
1. Try to login as a master account then run the command again (recommended)

2. If the above solution fails, you may need to extend the web app, then run the setproperty command on the new web app.

Error:

Cannot connect to SQL Server. SQLSERVERNAME not found. Additional error information from SQL Server is included below.
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.

Solution:

Make sure you are RDP’ed in with an account that has windows access to SQL Server

Oftentimes programmers have to deal with external third party DLLs that their software rely on to function. This is both smart and useful because as long as the DLL interface remains the same, externally linked DLLs can be easily swapped in and out without having to recompile and rebuild code. However, linking code in Visual Studio with an external library requires that a .lib file exist – the DLL is actually not sufficient for this task. Fortunately, there is a way to generate a .lib from a DLL with Visual Studio. Creating the .lib file is a bit like reverse engineering the DLL’s symbols.

1. Regardless of your Visual Studio version, whether it’s for 2003, 2005, or 2008 .NET, open up the Visual Studio Tools command promopt (something like Start -> Program Files -> Microsoft Visual Studio -> Visual Studio Tools -> Visual Studio Command Prompt).
2. If you have a .def file for your DLL, you can skip this step. Otherwise if your DLL did not ship with a .def file, you have a bit of work ahead of you. You cannot generate a .lib without a .def file first, sorry. To generate a .def file from a DLL, execute the dumpbin command to extract the function names from your DLL. In our example, we will be building from sqlite3.dll.
   dumpbin /exports C:\path\to\sqlite3.dllThe output appears below:
   The function names boxed in red are what you need to care about. Copy just the function name text into a new file with .def extension. Start the new file with "EXPORTS” without the quotes and then have each function on its own line like this:
   EXPORTS
sqlite3_aggregate_context
sqlite3_aggregate_count
sqlite3_auto_extension
sqlite3_bind_blob
sqlite3_bind_double
sqlite3_bind_int
sqlite3_bind_int64
...

3. With your new definition file in tow, in the command prompt you can execute the lib command to finally generate the .lib file:lib /def:C:\path\to\sqlite3.def /out:C:\path\to\sqlite3.lib /machine:x86
   This generates the .lib file you can use to link with in your project file. Note that the /machine argument can take any number of machine configuration so be sure to choose the correct one. To get a list of all machine types, simply type “lib” by itself. Here is the usage below for your edification:
   usage: LIB [options] [files]

   options:

   /DEF[:filename]
   /EXPORT:symbol
   /EXTRACT:membername
   /INCLUDE:symbol
   /LIBPATH:dir
   /LIST[:filename]

   /MACHINE:{AM33|ARM|EBC|IA64|M32R|MIPS|MIPS16|MIPSFPU|MIPSFPU16|MIPSR41XX|
SH3|SH3DSP|SH4|SH5|THUMB|X86}
/NAME:filename
/NODEFAULTLIB[:library]
/NOLOGO
/OUT:filename
/REMOVE:membername
/SUBSYSTEM:{CONSOLE|EFI_APPLICATION|EFI_BOOT_SERVICE_DRIVER|
EFI_ROM|EFI_RUNTIME_DRIVER|NATIVE|POSIX|WINDOWS|
WINDOWSCE}[,#[.##]]
/VERBOSE

And if you came looking for sqlite3.lib we just saved you a lot of time.

Server was unable to process request. —> Attempted to perform an unauthorized operation


queryService.Credentials = new System.Net.NetworkCredential(“username”,“password”,“domain”);

or you may want to try different passing

queryService.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;

or

NetworkCredential networkCredential = CredentialCache.DefaultCredentials.GetCredential(new Uri(queryService.Url), “NTLM”);

or

queryService.Credentials = networkCredential;

queryService.Credentials = System.Net.CredentialCache.DefaultCredentials;
queryService.PreAuthenticate = true;


What we found the error to be was:
1. Check to make sure account you are logging in with has authority to do so.

2. Make sure that you are able to connect to the sites search service (IE, make sure its working properly) Try to connect to other search services to debug issue – Most times default credentials so not work and you will need to login.

You can try to use the Search Service tool here:
http://www.mosssearch.com/searchwebservice.html
But that only allows you to login with default credentials and may fail some of the time.

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application’s trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request for the permission of type ‘System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed.

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

If you care getting the error above in SharePoint, there is a simple work around to get your code to work.

1. Open the wss_minimaltrust.config located: “C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\CONFIG”

2. Under the XML section <namedpermissionsets> and under the last <permissionset> add


<ipermission>
class="WebPermission"
version="1"
Unrestricted="true">
</ipermission>

3. Save the file and you are good to go!

The following code snippet shows how to generate a random number between a range in C#, where min and max are minimum and maximum range of the new number.

private int RandomNumber(int min, int max)
{
Random random = new Random();
return random.Next(min, max);
}

How to use it?

Copy the above code in your class where you want to use it and call like this:

int returnValue = RandomNumber(5, 20);
