I want to store a X509 certificate to a user store in Novell viathe ".NET C# LDAP Library" that Novell has developed [URL]I can store different entries like givenName, commonName, mail, description etc. etc. Everythings works fine :)But I can't store a certificate correctly because the final encoding of the certificate will be failed.I've tried to send the entire certificate as HEX and Base64 in strings and bytes but the final encoding will still be failed.

So my question is:Anyone who knows how I should encode the certificate before sending it?
I'm trying to get the groups a user is member of from an Open Ldap using vb.net 3.5.
Although so far I have managed to connect to the ldap server and get the user's info like sn, givenname, description, mail, adspath,
I have absolutely no information about the user's groups.
My code is like this:
Dim oEntry as New DirectoryEntry
Dim oSearcher as New DirectorySearcher
oEntry = New DirectoryEntry("LDAP://myServer/ou=test, dc=example, dc=com", username, pwd, AuthenticationTypes.ServerBind)
oSearcher = New DirectorySearcher(oEntry, "(uid=" & uName & ")")
oResult = oSearcher.FindOne()
if not oResult is Nothing then
Dim ADUser as DirectoryEntry
ADUSer = oResult.GetDirectoryEntry()
end if
Well, ADUser has no info on user membership whatsoever.
Am I doing something wrong? Should I use System.DirectoryServices.Protocols as I saw someone mentioning instead
of System.DirectoryServices or is .Protocols just for Framework 2.0?

I got exception at line Object obj = entry.NativeObject; and error message is: Invalid dn syntax specified. how can i take a right dn syntax? I tried some domain name such as: LDAP://localhost:389, [URL], ... but I still get this error

View 3 RepliesI'm working on a portal, and I need to check users conection on the ldap.
And if users are members of a special group then it works.
I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)
My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :
// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }
I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.
I have developed a web application which has LDAP authentication implemented.When I run the application though visual studio it works fine , LDAP works perfectly and allows if login name and password are correct.

I am a newbie on a LDAP, now we want to re-deploy a web application that will validate user name and password with AD in a login.aspx
I had success to check the user and password in VS 2008, but when I publish to server it don't work, (they can login even wrong username and password) I had enable the anonymous access and intergrated windows authentication on IIS. we using authentication mode = windows in our web.config
using something like the following to check the AD account
System.DirectoryServices.DirectoryEntry entry = null;
bool isOpened = false;
bool isSuccess = false;
try
{
string dom = System.Configuration.ConfigurationManager.AppSettings["domain"];
entry =
new System.DirectoryServices.DirectoryEntry("WinNT://" + dom, tb_username.Text.Trim(), tb_password.Text.Trim());
isOpened = true;
Object obj = entry.NativeObject;
but still no luck on IIS server. Would you mind to give me a hand to solve this issue, I had google for a week and still can't solve :(
