How to run a directorysearcher from one domain to another.

Hello,
I have an asp.net application developed which has a class that has directoryservices referenced in it. The purpose is to use the directory searcher(LDAP) to locate the details from an active directory. In this case lets say we have two domains. First domain called DomainA, and second one called DomainB.

Now I have my web server hosted on DomainB. However the active directory in that domain does not have many of the user details that I want, and so my asp.net application will have to look into DomainA active directory from the iis installed on DomainB.

What is the best way to do this.

I can't say about best method. But for problem I would have passed modified path for domain A as:

string adminPath = @"LDAP://DomainControllerB.Domain.Parts/OU=USERS,OU=RJSO,OU=MARKETING,DC=Domain,DC=Parts"/";

 DirectoryEntry AD= new DirectoryEntry(adminPath, adUser, adPass, AuthenticationTypes.Secure);

public static void ShowDetails(string adminPath)
    {
using (DirectorySearcher ds = new DirectorySearcher(AD))
                {
                    // Code implementation here
                }
}

// Code here for rechecking by passing adminPath and other fields for domain A to above function.
