i have a messaging app written in c++ (qt) and now i want to add a library to move heavy media via ftp to a ftp server and give the link to other user to download it.
the problem is there are to many users to create separate ftp accounts for all of them manually and using one account for all of them isn't safe.i want to limit every users access to their own subdirectory and delete that dir and ftp account if the users deletes account.
i think the following approaches makes sense:
1)in ftp server check login credentials submitted with ftp.login(user,password) in server with existing users in a sql database (users are added to database with signup and deleted with delete account)
2)adding a proxy server to check authorization to access ftp server and then give access to ftp server subdirectory
3)manually writing a ftp daemon for server with c++ or qt library and listen to a port
4)if there is a way to automatically add ftp user to ftp server when signing up
if there is another way i'd appreciate the help and if you have an idea how to implement one of the above please explain in detail
i tried to find a module in C++ to help build ftp server app but couldn't find any.
i found a way.pureFTPD is a ftp daemon that lets u use a sql database to validate ftp users and limit their access.

I'm having a server with power-bi reporting service installed and configured on it, and from my front-end that hosts the application, i've got angular 7 with proper power-bi components installed.
Since the report is on the server and it needs authentication to login, i get a user and password fill-in prompt in my website whenever i try to access this report, and after logging in, i can see the data of my report.
I'm wondering how to use Kerberos authentication so that i can set-up that username and password to login automatically without asking the user to enter them every time.
What i've done so far :
I've made and set a few SPN in my active directory, made a user in Active Directory Users and Computer and in it's Delegation tab, i've set it to Use any authentication protocol and added MSOLAPDisco and MSOLAPSvc.3 to it. i've added the user account credentials that i've made to service account and execution account in power bi Report server then i modified the rsreportserver config file to use the RSNegotiate before NTLM.
After trying to solve the issue with the mentioned above methods, i still get a NTLM method in network monitor which is installed in the Active Directory.
Any suggestions how to solve this issue? Thanks in advance.
I have two servers on a Windows domain that include an active directory that is correctly configured to allow users to login using smartcard credentials. Currently, I can login to server1 and run remote PowerShell commands on server2 using smartcard credentials through WinRM, without any problem.
I would like to build some sort of web service (preferably on node.js) on server1, so that it presents a user with a webpage that prompts for smartcard credentials. Using these credentials, server1 would be able to run remote PowerShell commands on server2.
Is this possible? I saw some references to pcsclite on other posts. Is this all I need? If so, could someone provide a code snip-it of something that could accomplish this?
Maybe a simpler question that could help me get started, would be how could I even use these credentials to connect to a file share on server2 and download a file?
Thanks!

I developed a webapplication Example1:7575 which uses FBA. Now, I deployed these WSP's to a new server Production:2525 to get the same functionality of my previous server's webapplication. However, I was not able to fetch the data from sql server and I'm getting the following error: A Membership Provider has not been configured correctly. Check the web.config setttings for this web application.
Actually, I have manually entered the same membership and role providers of my previous server's central admin, security service token & web application's web.config entries to this new web.configs and matched them.
Can someone help me with where I might be doing wrong. Any help would be greatly appreciated.
If you can't fetch data from SQL Server there's probably an issue with permissions to the database. Check the database connection string that FBA is using. It likely uses Windows authentication to connect - in which case it will be connecting as the user assigned to the app pool for the web application and the secure token service. Check that the configured app pool identities have permissions to access the sql server databases.
I want to make a connection between an external LDAP server (e.g. Active Directory server) and my webservice. I want to make sure that a certain group of users from the LDAP server stays in sync with my webservice, e.g. when a user gets deleted from the LDAP server, the LDAP server should push this change to my webservice so the user can be deleted from my webservice as well.
Any suggestions on how to achieve this?
The comments to your question indicate that you should retrieve data as required from the directory server instead of trying to maintain synchronization, with which I agree.
If synchronization is still your desire, you may be able to use persistent search, which notifies the connected client of changes in the database according to search parameters. Not all server support this mechanism, however.

We're having a hard time figuring how these credentials objects work. In fact, they may not work how we expected them to work. Here's an explanation of the current issue.
We got 2 servers that needs to talk with each other through webservices. The first one (let's call it Server01) has a Windows Service running as the NetworkService account. The other one Server02 has ReportingServices running with IIS 6.0. The Windows Service on Server01 is trying to use the Server02 ReportingServices WebService to generate reports and send them by email.
So, here's what we tried so far.
Setting the credentials at runtime (This works perfectly fine):
rs.Credentials = new NetworkCredentials("user", "pass", "domain");
Now, if we could use a generic user all would be fine, however... we are not allowed to. So, we are trying to use the DefaultCredetials or DefaultNetworkCredentials and pass it to the RS Webservice:
rs.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials
Or:
rs.Credentials = System.Net.CredentialCache.DefaultCredentials
Either way won't work. We're always getting 401 Unauthrorized from IIS. Now, what we know is that if we want to give access to a resource logged as NetworkService, we need to grant it to DOMAIN\MachineName$ (http://msdn.microsoft.com/en-us/library/ms998320.aspx):
Granting Access to a Remote SQL Server
If you are accessing a database on another server in the same domain (or in a trusted domain), the Network Service account's network credentials are used to authenticate to the database. The Network Service account's credentials are of the form DomainName\AspNetServer$, where DomainName is the domain of the ASP.NET server and AspNetServer is your Web server name.
For example, if your ASP.NET application runs on a server named SVR1 in the domain CONTOSO, the SQL Server sees a database access request from CONTOSO\SVR1$.
We assumed that granting access the same way with IIS would work. However, it does not. Or at least, something is not set properly for it to authenticate correctly.
So, here are some questions:
We've read about "Impersonating Users" somewhere, do we need to set this somewhere in the Windows Service ?
Is it possible to grant access to the NetworkService built-in account to a remote IIS server ?
Thanks for reading!
All details you need are included in this very old article
In short, when you find it confusing to troubleshoot issues like this, you should first review the technical details behind ASP.NET impersonation carefully.
Here are some things you could check out:
- set an SPN (Service Principal Name) for the reporting service; you can find good examples in google;
- Allow delegation (ClientCredentials.Windows.AllowImpersonationLevel)
Is the problem that you're failing to authenticate to IIS, or failing to authenticate to SSRS? The DOMAIN\MachineName$ account may need to be granted permission in SSRS to run the report you're trying to automate.
SSRS usually does a pretty good job of getting IIS configured correctly, so you shouldn't need to mess with those settings. I double-checked my installation (which is SSRS 2005, things may have worked differently in SSRS 2000 and you didn't say which version you're running), and it's set to use Windows authentication and has impersonation enabled. That means IIS should basically just be authenticating your credentials (validating a correct username/password), not authorizing (determining whether that user has permission to run the report in question). IIS then passes the credentials on to SSRS, which has its own settings for determining what accounts have permission to view reports.
Also, you can automate sending reports on a scheduled basis directly in SSRS, so you may not need the Windows service at all if your scheduling is fairly basic (i.e., daily, weekly, etc.).
