How to pass userid to ldap apache server in ASP.NET Core?

public User Login()

{

string userid = "user1";

string ldapHost = "localhost:10389";

string searchBase = "o = company";

string searchFilters = "(objectClass=inetOrgPerson)(uid={0})";

int port = 389;

ldapConn.Connect(ldapHost, port);

ldapConn.Bind("uid = admin, ou = system", "secret");

var SearchFilters = string.Format(searchFilters, userid);

LdapSearchResults results = ldapConn.Search(searchBase,

LdapConnection.SCOPE_SUB,

SearchFilters,

null,

false

);

var user = results.next();

}

In var user I always a details of user3 randomly weather I pass uid or not?

How will I get particular user on bases of uid from ldap apache server I using novel directory extension in Asp.Net core.

Hi Kiran,

The first thing I had to do was install the Nuget package

Install-Package Microsoft.Windows.Compatibility

Then, add using statements for System.DirectoryServices and System.DirectoryServices.AccountManagement

Then, just plug this logic into my HandleAuthenticateAsync method:

const string LDAP_PATH = "EX://exldap.example.com:5555";
const string LDAP_DOMAIN = "exldap.example.com:5555";
using (var context = new PrincipalContext(ContextType.Domain, LDAP_DOMAIN, "service_acct_user", "service_acct_pswd")) {
if (context.ValidateCredentials(username, password)) {
using (var de = new DirectoryEntry(LDAP_PATH))
using (var ds = new DirectorySearcher(de)) {
// other logic to verify user has correct permissions
// User authenticated and authorized
var identities = new List { new ClaimsIdentity("custom auth type") };
var ticket = new AuthenticationTicket(new ClaimsPrincipal(identities), Options.Scheme);
return Task.FromResult(AuthenticateResult.Success(ticket));
}
}
}
// User not authenticated
return Task.FromResult(AuthenticateResult.Fail("Invalid auth key."));
