I need to connect to NetIQ eDirectory using .NET & C#. The connection must be opened using application credentials. Once the connection is opened, I need to validate user credentials under the authority of the application credentials using a similar method as S.DS.AccountManagement.
using (var context = new PrincipalContext(ContextType.Domain, path, appUserDn, appPassword))
{
//Username and password for authentication.
var valid = context.ValidateCredentials(userDn, password);
}
I tried Novell.Directory.Ldap, S.DS.DirectoryEntry, & S.DS.AccountManagement. The last one requires AD and does not apply.
Test using Novell.Directory.Ldap..
using (var cn = new LdapConnection())
{
cn.Connect(server, int.Parse(port));
cn.Bind(appUserDn, appPassword); //throws exception if invalid credentials..
var passwordAttr = new LdapAttribute("userPassword", password);
cn.Compare(userDn, passwordAttr); // Only compares password, so no locked account check, etc.
}
My current prototype uses S.DS.Protocols.
var networkCredential = new NetworkCredential(
appUserDn,
appPassword);
using (proto.LdapConnection cn = new proto.LdapConnection(new proto.LdapDirectoryIdentifier(server, int.Parse(port)), networkCredential, proto.AuthType.Basic))
{
cn.Bind();
/// Next validate user credentials..
}
I cannot find a way to validate user credentials other than reassigning NetworkCrentials and rebinding using the individual's username & password. How should I proceed?
It turns out our client got it wrong. The correct way is to bind the connection directly to an individual's credentials as I demonstrate in the Novell.Directory.Ldap example.
There was a posting on NetIQ's forum about executing a shell script but I did not get it working.

I'm trying to connect to SharePoint online in a console App and print the title of the site.
Its giving me the error : "The sign-in name or password does not match one in the Microsoft account system."
I have checked and made sure the username and password are 100% right.
I dont know what else to check
Heres my code:
private static void SPCredentialsConnect()
{
const string SiteUrl = "https://tenant.sharepoint.com/sites/mysite";
const string pwd = "appPassword";
const string username = "username#tenant.onmicrosoft.com";
SecureString securestring = new SecureString();
pwd.ToCharArray().ToList().ForEach(s => securestring.AppendChar(s));
ClientContext context = new ClientContext(SiteUrl);
context.Credentials = new SharePointOnlineCredentials(username, securestring);
try
{
var web = context.Web;
context.Load(web);
context.ExecuteQuery();
Console.WriteLine($"web title: {web.Title}");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
Have your issue fixed? “The sign-in name or password does not match one in the Microsoft account system” Error will occur sometimes and fixed after a while with nothing changed.
AppOnly Authentication for sharepointonline can't be registed in Azure Active Directory.
It should be register in
https://contoso.sharepoint.com/_layouts/15/appregnew.aspx
And grant permission in
https://contoso-admin.sharepoint.com/_layouts/15/appinv.aspx
You can refer to following document
https://learn.microsoft.com/en-us/sharepoint/dev/solution-guidance/security-apponly-azureacs
Consider using the PnP.Framework (a NuGet package), and use the AuthenticationManager object for SPO sites. This method bypasses MFA (which is mandatory in our organization, FWIW). You can find a lot more information and examples here, including steps on getting the client id and client secret for a site. Here is what we use to log into SPO sites:
using (ClientContext context =
new AuthenticationManager().GetACSAppOnlyContext(SiteUrl, clientID, clientSecret))
{
...
}
Also, once you connect, you should adjust the Context.Load to grab the title if you want to use that value right away. Here's what I used in my code:
context.Load(web, p => p.Id, p => p.Title);
context.ExecuteQuery();
Console.WriteLine($"Logged into source {web.Title} ({web.Id})");
Good luck!

I have an instance of AD/LDS running on my machine and I'm trying to connect to it using the System.DirectoryServices.Protocols.LdapConnection class. For some reason every time I call the Bind() method it throws an LdapException complaining about invalid credentials.
Here's the code I'm using to set up the connection:
var ldapDirectoryIdentifier = new LdapDirectoryIdentifier(config.Server.Host, config.Server.Port);
var creds = new NetworkCredential(config.Credentials.Username, config.Credentials.Password)
{
Domain = config.Credentials.
};
ldapConnection = new LdapConnection(ldapDirectoryIdentifier, creds, AuthType.Basic);
if (config.Server.Secure)
{
cert = new X509Certificate(config.Server.Certificate);
ldapConnection.SessionOptions.SecureSocketLayer = true;
ldapConnection.SessionOptions.VerifyServerCertificate = CheckCertificate;
}
ldapConnection.SessionOptions.ProtocolVersion = 3;
try
{
ldapConnection.Bind();
}
catch (LdapException e)
{
Log.LogException(e);
Environment.Exit(e.ErrorCode);
}
The configuration is coming from an App.config file as in the following example:
<server host="host" port="389"/>
<credentials username="username" password="password" domain="domain"/>
<usersearch base="ou=test,dc=test,dc=com" filter="(middlename=user)" objectclass="inetorgperson"/>
<devicesearch base="ou=test,dc=test,dc=com" filter="(sn=device)" objectclass="inetorgperson"/>
I've tried modifying the credentials part to get it connecting; setting username="DOMAIN\user", with and without the domain entry to credentials. I've tried messing with the connection strings, e.g. <server host="LDAP://host[:389]"/>. It just says the credentials, which I use to connect to the instance with both ADSI Edit and ldp, are invalid.
I CAN connect with the same domain credentials (local user account) using System.DirectoryServices.DirectoryEntry so I suspect it's the AD bit of AD/LDS being picky.
Anyone got any ideas?
It's probably on the session option. Try to force authentication type:
ldapConnection.AuthType = AuthType.Negotiate;
It may also be the way you handle the certificate. Try to add it this way:
ldapConnection.ClientCertificates.Add(cert);
I went ahead and double checked what AuthTypes were available and setting it to Ntlm works.
I keep getting the following error when trying to connect to an LDAP server. The user name or password is incorrect.
It occurs on the .FindOne()
If I use AuthenticationTypes.Encryption i get an error: The server is not operational.
I've also tried to prepend the username with ownme\username
I'm extremely newbish with AD so the issue might be so simple.
Domain = domain;
_entry = new DirectoryEntry("LDAP://DC1/DC=ownme,DC=local", username, password, AuthenticationTypes.ServerBind);
_directorySearcher = new DirectorySearcher(_entry, "(objectClass=*)", new string[] {"namingContexts"}, SearchScope.Subtree);
var namingContext = _directorySearcher.FindOne();
The problem was credentials. You need to specify the domain prefix in the username or look at one of the comments in my question.
I had var username = "domain\username";
I should have written var username = #"domain\username";
I'm a total newbie to this
Trying to connect to an ldap server with PrincipalContext. I have tried all solutions on this site to no avail.
Things I've tried:
PrincipalContext insPrincipalContext =
new PrincipalContext(ContextType.Domain);
PrincipalContext insPrincipalContext =
new PrincipalContext(ContextType.Domain, "ldap://localhost:389/dc=maxcrc,dc=com");
PrincipalContext insPrincipalContext =
new PrincipalContext(ContextType.Domain, "maxcrc.com");
All give the same result:
LDAP server not available
Only ContextType.Machine works basically.
Not sure if my LDAP server is set up correctly:
Host: localhost
Port: 389
Base DN: dc=maxcrc,dc=com
URL: ldap://localhost:389/dc=maxcrc,dc=com
Testing with Softerra LDAP Browser
Any tutorials from start to finish will be much appreciated...
I have been facing the same issue and I found a solution.
I'm able to connect easily using following code:
ADUser_Id = "domainName\\username"; //make sure user name has domain name.
Password = "xxxx";
var context = new PrincipalContext(ContextType.Domain,"server_address", ADUser_Id,Password);
/* server_address = "192.168.15.36"; //don't include ldap in url */
I had similar issues. It turned out that I had to pass username and password in the object initialization. Please try using a statement like below:
PrincipalContext insPrincipalContext =
new PrincipalContext(ContextType.Domain,
"ldap://localhost:389/dc=maxcrc,dc=com",
userName,
password);
Also make sure that your username has domain in it.
For example,
userName = "mydomainname" + "\\" + "john_jacobs"
Use the following constructor overload for PrincipalContext:
public PrincipalContext(
ContextType contextType,
string name,
string container
)
And separate the server name from the LDAP string:
PrincipalContext insPrincipalContext =
new PrincipalContext(ContextType.Domain, "localhost:389", "dc=maxcrc,dc=com");
https://msdn.microsoft.com/en-us/library/bb348316%28v=vs.110%29.aspx
In my environment I had to create the principal context with just the domain controller host name, and then separately validate the user credentials.
string domainControllerName = "PDC";
string domainName = "MyDomain"; // leave out the .Local, this is just to use as the prefix for the username if the user left it off or didn't use the principal address notation
string username = "TestUser";
string password = "password";
using (var ldap = new PrincipalContext(ContextType.Domain, domainControllerName))
{
var usernameToValidate = username;
if (!usernameToValidate.Any(c => c == '#' || c == '\\'))
usernameToValidate = $"{domainName}\\{username}";
if (!ldap.ValidateCredentials(username, context.Password, ContextOptions.SimpleBind))
throw new UnauthorizedException();
}
This example allows for all three of these variations to the username to validate:
TestUser
MyDomain\TestUser
TestUser#MyDomain.Local
You may want to try your local machine address instead :
ldap://127.0.0.1:389/dc=maxcrc,dc=com
If that doesn't work, I'd fire up Wireshark, and have it capture traffic on port 389 as you're attempting to connect via Softerra.
In my time working with LDAP and .Net DirectoryServices, that error usually means the syntax or naming convention of the path is incorrect, or does not point to a valid directory end point.
That error might be due to trying to connect as "Anonymous" without specifying it explicitly.
By default all connections are Negotiable. So if you try something like that you could try the following:
LdapDirectoryIdentifier ldap = new LdapDirectoryIdentifier("My Hostname or IP Address",10389); //10389 might be your non default port
LdapConnection connection = new LdapConnection(ldap);
connection.AuthType = AuthType.Anonymous;
I need to connect to an external LDAP server that is accessible to me but only over LDAPS.
The information I have available is username, server, password. I need to query and retrieve a list of all users. The format I have the details in are
Username: domain\username
Password: {password}
Domain: remote.{domain}.net.au
The following code I wrote will authenticate my user account successfully, but I now need to enumerate all users which is where I'm having issues. Ideally this would be ALL users in the directory, not from within a specific OU. Again, I don't have the fully qualified paths to any OUs for this server. The server has a self signed certificate which is why in my example I am specifically telling it to accept the certificate.
int port = secured ? 636 : 389;
LdapConnection connection = new LdapConnection(new LdapDirectoryIdentifier(ldapServer, port, false, false));
if (secured)
{
connection.SessionOptions.ProtocolVersion = 3;
connection.SessionOptions.SecureSocketLayer = true;
}
connection.Credential = new NetworkCredential(username, password);
connection.AuthType = AuthType.Basic;
connection.SessionOptions.VerifyServerCertificate += (conn, cert) => { return true; };
connection.Bind();
return connection;
So the answer is in Performing a Simple Search sample of Introduction to System.DirectoryServices.Protocols (S.DS.P) with :
// create a search filter to find all objects
string ldapSearchFilter = "(&(objectCategory=person)(objectClass=user))";
