ASP.net and GAC

[SP]

Hello there,

I have a following peice of code which access AD.

When I place the code in ASP.net page it works fine.

but when I create a class and put the code in the class, and then
compile the class and register it in the GAC, and reference it in my
ASP.net project,and create a instance of the class and call the method
which holds the method, I get an error.

below is the code, does the security context change when the class is
being called?, I have set impersonisation to true in the web
application

Please suggest!

Thanks,
SP

public string itnMembersOf()
{

string tmp1 = "";

DirectoryEntry my_ent = new
DirectoryEntry("LDAP://immunetolerance.org/OU=testou1,OU=testou2,DC=immunetolerance,DC=org");

my_ent.Username = "(e-mail address removed)";
my_ent.Password = "pass";

DirectorySearcher my_srch = new DirectorySearcher(my_ent);
my_srch.Filter = "(SAMAccountName=spai)";
SearchResult my_result = my_srch.FindOne () ;

DirectoryEntry my_ent1 = my_result.GetDirectoryEntry();
my_ent1.Username = "(e-mail address removed)";
my_ent1.Password = "pass";
my_ent1.RefreshCache(new string[] {"tokenGroups"});

I have a car. What can you tell me about this car? You have an error. What
can I tell you about this error?

Not much. Could you describe the error, please? what is the type of
exception? What is the message? What does the stack trace in the exception
tell you about where the exception occurred?
