But I really don\'t get how to connect via LDAP.

Can so

Answer 1

If your email address is 'myname@mydomain.com', try changing the createDirectoryEntry() as below.

XYZ is an optional parameter if it exists in mydomain directory

static DirectoryEntry createDirectoryEntry()
{
    // create and return new LDAP connection with desired settings
    DirectoryEntry ldapConnection = new DirectoryEntry("myname.mydomain.com");
    ldapConnection.Path = "LDAP://OU=Users, OU=XYZ,DC=mydomain,DC=com";
    ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
    return ldapConnection;
}

This will basically check for com -> mydomain -> XYZ -> Users -> abcd

The main function looks as below:

try
{
    username = "Firstname LastName"
    DirectoryEntry myLdapConnection = createDirectoryEntry();
    DirectorySearcher search = new DirectorySearcher(myLdapConnection);
    search.Filter = "(cn=" + username + ")";
    ....
