Attempting to validate id against Active Directory

[Ted Vreeland via DotNetMonster.com]

Hi Folks,

I've got a intranet ASP.NET page that takes a user id (e.g. 'DoeJ') passed in and attempts to get the First and Last name of the user from the Active Directory. I'm running into some issues and am hoping someone can look at it and tell me whats wrong. I've gotten several different errors (Referal from server, unspecified error, etc). Any assistance would be greatly appreciated.

Best Regards,
Ted

CODE:
-----------------
DirectoryEntry _de = new DirectoryEntry( "LDAP://rootDSE" );
string _DomainPath = _de.Properties["DefaultNamingContext"][0].ToString();
DirectoryEntry _root = new DirectoryEntry( _DomainPath );
DirectorySearcher _src = new DirectorySearcher( _root);
_src.Filter = "(&(objectCategory=Person)(SAMAccountName=" + Request["DomainId"] + ")";

_src.PropertiesToLoad.Add( "givenname" );
_src.PropertiesToLoad.Add( "sn" );
_src.PropertiesToLoad.Add( "mail" );

SearchResult _res = _src.FindOne();

firstName = _res.Properties["givenname"][0].ToString();
lastName = _res.Properties["sn"][0].ToString();

Ted,

Questions about AD are best posted in the microsoft.public.adsi.general
newsgroup where the two Joe's will be most help, but in answer to your
problem i think this should work

DirectoryEntry _root = new DirectoryEntry (@"LDAP://rootdse");
string path = _root.Invoke("GET","defaultNamingContext").ToString();
DirectoryEntry _de = new DirectoryEntry ("LDAP://" + path);
DirectorySearcher _src = new DirectorySearcher( _de);
_src.Filter = "sAMAccountName=XXXXXXX";
_src.PropertiesToLoad.Add( "givenname" );
_src.PropertiesToLoad.Add( "sn" );
_src.PropertiesToLoad.Add( "mail" );
SearchResult _res = _src.FindOne();
firstName = _res.Properties["givenname"][0].ToString();
lastName = _res.Properties["sn"][0].ToString();

I found the problem - I needed the <identity impersonate="true" /> setting added to the web.config - that allowed the AD query to run under the identity of the logged in user.

Thanks for the help anyway.
