  • Accessing facebook sdk result Object using .NET 3.5 API?

    - by John K
    Consider the following in .NET 3.5 (using the Bin\Net35\Facebook*.dll assemblies): using Facebook; var app = new FacebookApp(); var result = app.Get("me"); // want to access result properties with no dynamic ... in the absence of the C# 4.0 dynamic keyword this provides only generic object members. How best should I access the facebook properties of this result object? Are there helper or utility methods or stronger types in the facebook C# SDK, or should I use standard .NET reflection techniques?

    Hi, In order to make full use the Facebook like button, I am trying to switching from iframe-based like button to js-based like button. url: http://www.dealsvista.com Everything works fine for a user who is logged into Facebook. However, for a user who is not logged into Facebook, when he clicks the like button, there is a error in the popup window. Could someone point me to the right direction? I am really new to Facebook api and have no idea what is going on? Do I have to implement connect at the same time? Do I have to set up the connect call back url in my apps?

  • ASP.Net Authentication with MVC2--how to integrate with DB?

    - by alchemical
    I'm trying to understand the authentication section sample project that opens in a new MVC2 project in VS2010. It essentially lets you register, login, etc. I looked through the code that implements this briefly, it looked fairly complicated. (10 tables, 40 sprocs, 10 views, 4 models, 1 model, 1 controller, etc.) Is it best to utilize this provided framework for authentication? If so, how would I integrate this with my own database models (which has user and role tables, etc.). Also, if I use their framework, are there any performance issues at higher traffic volumes (like SO for example), do I need to become responsible for maintaining the authentication DB as well in this case?

  • Using MAC Authentication for simple Web API’s consumption

    - by cibrax
    For simple scenarios of Web API consumption where identity delegation is not required, traditional http authentication schemas such as basic, certificates or digest are the most used nowadays. All these schemas rely on sending the caller credentials or some representation of it in every request message as part of the Authorization header, so they are prone to suffer phishing attacks if they are not correctly secured at transport level with https. In addition, most client applications typically authenticate two different things, the caller application and the user consuming the API on behalf of that application. For most cases, the schema is simplified by using a single set of username and password for authenticating both, making necessary to store those credentials temporally somewhere in memory. The true is that you can use two different identities, one for the user running the application, which you might authenticate just once during the first call when the application is initialized, and another identity for the application itself that you use on every call. Some cloud vendors like Windows Azure or Amazon Web Services have adopted an schema to authenticate the caller application based on a Message Authentication Code (MAC) generated with a symmetric algorithm using a key known by the two parties, the caller and the Web API. The caller must include a MAC as part of the Authorization header created from different pieces of information in the request message such as the address, the host, and some other headers. The Web API can authenticate the caller by using the key associated to it and validating the attached MAC in the request message. In that way, no credentials are sent as part of the request message, so there is no way an attacker to intercept the message and get access to those credentials. Anyways, this schema also suffers from some deficiencies that can generate attacks. For example, brute force can be still used to infer the key used for generating the MAC, and impersonate the original caller. This can be mitigated by renewing keys in a relative short period of time. This schema as any other can be complemented with transport security. Eran Rammer, one of the brains behind OAuth, has recently published an specification of a protocol based on MAC for Http authentication called Hawk. The initial version of the spec is available here. A curious fact is that the specification per se does not exist, and the specification itself is the code that Eran initially wrote using node.js. In that implementation, you can associate a key to an user, so once the MAC has been verified on the Web API, the user can be inferred from that key. Also a timestamp is used to avoid replay attacks. As a pet project, I decided to port that code to .NET using ASP.NET Web API, which is available also in github under https://github.com/pcibraro/hawknet Enjoy!.

  • openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

    - by JoJoeDad
    I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

  • How To Use Google Authenticator and Other Two-Factor Authentication Apps Without a Smartphone

    - by Chris Hoffman
    Google, Dropbox, LastPass, Battle.net, Guild Wars 2 – all these services and more offer two-factor authentication apps that work on smartphones. If you don’t have a supported device, you can run an alternative application on your computer. When you log in, you’ll need to enter a time-based code from the app. Two-factor authentication prevents people who know your password – but don’t have the app and its security key – from logging in.

  • Is it possible to configure simultaneous authentication against 2 different AD domains by IIS 7?

    - by just3ws
    Basically, I need to be able to attempt to authenticate against two different AD domains from IIS. I'd like to be able to automatically query both AD's and whichever comes back with an authentication wins. The users are completely separate and will only exist in their respective domain.         IIS           |           |   /-------------\   |                 |  ------        ------  AD1         AD2  JoeU        AmyU  JillU         JohnU So, if IIS requests to authenticate JoeU it will query both domains. JoeU will be found in AD1 so we can ignore whatever response comes back from AD2. Is this even possible using stock IIS 7? Is there a middleware or something to allow this type of configuration on IIS 7? Would this be a job for some kind of middleware sitting between IIS and the AD domains?

  • Getting Apache to serve same directory with different authentication over SSL?

    - by Lasse V. Karlsen
    I have set up VisualSVN server, a Subversion server that internally uses Apache, to serve my subversion repositories. I've managed to integrate WebSVN into it as well, and just now was able to get it to serve my repositories through WebSVN without having to authenticate, ie. no username or password prompt comes up. This is good. However, with this set up there is apparently no way for me to authenticate to WebSVN at all, which means all my private repositories are now invisible as far as WebSVN goes. I noticed there is a "Listen 81" directive in the .conf file, since I'm running the server on port 81 instead of 80, so I was wondering if I could set up a https:// connection to a different port, that did require authentication? The reason I need access to my private repositories is that I have linked my bug tracking system to the subversion repositories, so if I click a link in the bug tracking system, it will take me to diffs for the relevant files in WebSVN, and some products are in private repositories. Here's my Location section for WebSVN: <Location /websvn/> Options FollowSymLinks SVNListParentPath on SVNParentPath "C:/Repositories/" SVNPathAuthz on AuthName "Subversion Repository" AuthType Basic AuthBasicProvider file AuthUserFile "C:/Repositories/htpasswd" AuthzSVNAccessFile "C:/Repositories/authz" Satisfy Any Require valid-user </Location> Is there any way I can set up a separate section for a different port, say 8100, that does not have the Satisfy Any directive there, which is what enable anonymous access. Note that a different sub-directory on the server is acceptable as well, so /websvn_secure/, if I can make a location section for that and effectively serve the same content only without the Satisfy Any directive, that'd be good too.

  • How can I disable Kerberos authentication for only the root of my site?

    - by petRUShka
    I have Kerberos-based authentication and I want to disable it on only root url: http://mysite.com/. And I want it to continue to work fine on any other page like http://mysite.com/page1. I have such things in my .htaccess: AuthType Kerberos AuthName "Domain login" KrbAuthRealms DOMAIN.COM KrbMethodK5Passwd on Krb5KeyTab /etc/httpd/httpd.keytab require valid-user I want to turn it off only for root URL. As workaround it is possible to turn off using .htaccess in virtual host config. Unfortunately I don't know how to do it. Part of my vhost.conf: <Directory /home/user/www/current/public/> Options -MultiViews +FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> UPD. I'm using Apache/2.2.3 (Linux/SUSE) I tried to use such version of .htaccess: SetEnvIf Request_URI ^/$ rootdir=1 Allow from env=rootdir Satisfy Any AuthType Kerberos AuthName "Domain login" KrbAuthRealms DOMAIN.COM KrbMethodK5Passwd on Krb5KeyTab /etc/httpd/httpd.keytab require valid-user Unfortunately such config turn Kerberos AuthType for all URLs. I tried to place first 3 lines SetEnvIf Request_URI ^/$ rootdir=1 Allow from env=rootdir Satisfy Any after main block, but it didn't help me.

  • flash twitter and facebook widgets

    - by NorthPole
    I'm stuck with a crappy digital signage platform that only renders .html and .swf files (and rss feeds) No customization of rss, only way to show something dynamic in a pretty way is to use flash. The question: is there any way to embed javascript in swf files or somehow have facebook and twitter flash plugins? I looked for ready-made swf widgets for the job but didn't find any, if there is any flash widget that serves a facebook and/or twitter feed please give me a link. (sorry if the question is out of context but these things usually run a stripped-down browser to display everything so its pretty much a web page run from a file and not a web server)

  • Security settings for this service require 'Basic' Authentication

    - by Jake Rutherford
    Had an issue calling WCF service today. The following exception was being thrown when service was called:WebHost failed to process a request. Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/35320229 Exception: System.ServiceModel.ServiceActivationException: The service '/InteliChartVendorCommunication/VendorService.svc' cannot be activated due to an exception during compilation.  The exception message is: Security settings for this service require 'Basic' Authentication but it is not enabled for the IIS application that hosts this service..Ensured Basic authentication was indeed enabled in IIS before getting stumped on what actual issue could be. Turns out it was CustomErrors setting. Value was set to "off" vs "Off". Would have expected different exception from .NET (i.e. web.config parse exception) but it works now either way.
