An operations error occurred while accessing active directory

[dhanashivam]

hi all

i am doing a web site with single sign on technique. I am getting the error "COMExcepti on (0x80072020): An operations error occurred" while executing the statement

foreach (SearchResult AdObj in objsearch.FindA ll())

I can run the application in the local server but not by remote client. so please tell me the solution for it.

the code is:

strAppPath = "LDAP://myServer/CN=user,CN=user s,DC=sample,DC= testprjs,DC=com "

public bool authenticateUse r(string userName, string password)
{
DataTable dtDBUser = new DataTable("User InDB");
dtDBUser.Column s.Add("UName");
dtDBUser.Column s.Add("Pwd");
dtDBUser.Column s.Add("UDomain" );

DataRow dr;
dr = dtDBUser.NewRow ();
dr[0] = "gdhanasekaran" ;
dr[1] = "dhana";
dr[2] = "chennai";
dtDBUser.Rows.A dd(dr);

DirectoryEntry deRoot = new DirectoryEntry( strAppPath);
DirectorySearch er objsearch = new DirectorySearch er();
objsearch.Filte r = "(objectClass=u ser)";
objsearch.Searc hScope = SearchScope.Sub tree;
string strCN = "";
foreach (SearchResult AdObj in objsearch.FindA ll())
{
strCN += //System.Director yServices.Activ eDirectory.Doma in.GetCurrentDo main().Name + "\n" +
AdObj.Propertie s["SAMAccountName "][0] + "\n";
if (userName == Convert.ToStrin g(AdObj.Propert ies["SAMAccountName "][0]))
{
if (dtDBUser.Selec t("UName = '" + userName + "' ").Length > 0)
{
return true;
}
else
{
return false;
}
}
}
return false;
}

Thanks in Advance.

hi,

thanks for your reply. but i could not achieve the task. The article describes how to make the web site as accesible for all the users.

but i need to get the list of users from the active directory thru my web site. The site works fine while running from the server as well as not working from the remote machine.

thats why i am requesting to create an user who has the permissions to access the active directory.

please help me.

hi,

i got conclusion for accessing the active directory.

the IIS settings for the site which access the active directory should have the following.

1. Check the Annonymous access

2. Give a valid domain user name and its password in the specified portion.

3. Clear Allow IIS to Control password.

4. Check the Integrated Windows Authentication.

5. Add the Impersonate = true in your web.config file.

By these settings only you can read the users from the active directory.

Absense of anyone will not allow you to access the active directory
