  • Ask StackOverFlow : Canny a LightWeight Authorization library in Java

    - by eltados
    In the course of my work i need to develop an authorization engine ( i'm already authenticated and i check access of a user to an action ) in order to store all the authorization logic inside a same place and be able to reuse it and i have created the mini library. http://github.com/eltados/canny (updated) what do you think about it? What are the limits of my approch ? Do you understand the benefit or it? Is there any lightweight Authorization engine library i could have a look at? I had a look at spring security and it does not really answer my requirement. The main idea is that i want to be able to reuse the same code to controll access in the controllers and the views.

  • Multiple CAS servers with Microsoft Exchange and selective authorization

    - by John Wilcox
    I have a Microsoft Exchange 2010 organization within one Microsoft Windows domain and I have users accessing it through OWA. For simplicity lets say I currently have one CAS server (CAS 1) which is accessible only through a VPN connection. Lets call the users connecting to the first CAS group a. For some users though, I need to install another CAS server (CAS 2) so that they can connect without using a VPN connection. Lets call those users group b. What I need to achieve is that group a can only log in to CAS 1 and group b can only log in to CAS 2. Now I know that one can disable/enable OWA per user but in my case that is not enough because OWA must be enabled for both groups.

  • "Half" ssh authorization to a server with git repository

    - by hsz
    Hello ! Currently I have purchased web hosting with ssh access. I have created a git repository on it and if I set my public key in ~/.ssh/authorized_keys file, I have access to that repo, I can push/pull data, etc. This solution allows access for every user that has his public key in authorized_keys file. But there is one thing that I want to avoid. Every user can login to the server too and has access to whole ssh account. Is it possible to create a blacklist of users' keys that will not have an access to ssh ? I see it that way: user logs in to a git - ok, allow for every one user logs in to ssh account ~/.profile file is hooked and called a custom script: check user's public key if public key is in ~/.ssh/blacklist_keys call bash exit/logout Is it possible in any way ?

  • How to decouple trac from or align trac with apache authorization

    - by Laizer
    I've had a trac server running for about a year now - chugging along just as expected. Today, I implemented basic authorization on the apache server that trac runs under. Trac now picks up the user as authenticated by Apache, and doesn't allow either logout or a login. I tried to create an apache user with the same name and password as a trac user, but the behavior remained - I can't access trac. How do I align trac with Apache authorization?

  • Flex URLRequest and .NET authorization

    - by user252160
    can I make role based authorization when sending requests to an ASP.NET MVC backend system. I am calling action methods and expecting JSON results, however, some action methods are decorated with the [Authorize] attribute, others require some role privileges to be present. I certainly hope that passing authorization data with every request is possible

  • Twitter authentication without authorization

    - by user325377
    I wish to get the tweeter usename of a visitor to my site. I do not wish to post statuses or access any other information. I'd be happy to use OAuth, possibly with a 'Sign in with Twitter' button, but this then takes the user to a page which requests authorization for the application, that I wish to avoid. Is there a way to get the username without authorization? Thanks, Daniel

  • Program error trying to generate Outlook 2013 email from Visual Basic 2010 [on hold]

    - by Dewayne Pinion
    I am using vb to send emails through outlook. Currently we have a mix of outlook versions at our office: 2010 and 2013 with a mix of 32 bit and 64 bit (a mess, I know). The code I have works well for Outlook 2010: Private Sub btnEmail_Click(sender As System.Object, e As System.EventArgs) Handles btnEmail.Click CreateMailItem() End Sub Private Sub CreateMailItem() Dim application As New Application Dim mailItem As Microsoft.Office.Interop.Outlook.MailItem = CType(application.CreateItem( _ Microsoft.Office.Interop.Outlook.OlItemType.olMailItem), Microsoft.Office.Interop.Outlook.MailItem) 'Me.a(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem) mailItem.Subject = "This is the subject" mailItem.To = "[email protected]" mailItem.Body = "This is the message." mailItem.Importance = Microsoft.Office.Interop.Outlook.OlImportance.olImportanceLow mailItem.Display(True) End Sub However, I cannot get this to work for 2013. I have referenced the version 15 dll for 2013 and it seems to be backward compatible, but when I try to use the above code for 2013 (it is 64 bit) it says it cannot start Microsoft Outlook. A program error has occured. This is happening on the application Dim statement line. I have tried googling around but there doesn't seem to be much out there referencing 2013 but I feel that the problem here probably has more to do with 64 bit than the software version. Thank you for any suggestions!

  • Visual Basic link to SQL output to Word

    - by CLO_471
    I am in need of some advice/references. I am currently trying to develop a legal document interface. There are certain fields in which I need to query out of my sql db and have those fields output into a document that can be printed. I am trying to develop a user interface where people can enter fields that will output to a document template but at the same time I need the template to be able to pull data from the SQL database. This is the reason why I think that VB might be my best choice and because it is one of the only OOP languages I am familiar with presently. Does anyone know that best way to be able to handle this type of job?? I know that you can use VBA within MS Word and have the form output variables to a word template. But, is there a way to have the word document also pull information from the SQL db? Is the best option to use VB linked to SQL and run queries to get the information from the database and then have it output to a for within VB? Is it possible for VB to be linked to a SQL db and output variables and SQL fields to a Word Template? I have looked into Mail Merge and I see that it allows users to pull data from an Access query but I dont think it would be easy to automate and it seems that users would need to have an advanced knowledge of MS Word and Access to handle this. I am not finding much useful information online so I came here. Any advice or references would be greatly appreciated. If there is a better way please let me know.

  • converting dates things from visual basic to c-sharp

    - by sinrtb
    So as an excercise in utility i've taken it upon myself to convert one of our poor old vb .net 1.1 apps to C# .net 4.0. I used telerik code conversion for a starting point and ended up with ~150 errors (not too bad considering its over 20k of code and rarely can i get it to run without an error using the production source) many of which deal with time/date in vb versus c#. my question is this how would you represent the following statement in VB If oStruct.AH_DATE <> #1/1/1900# Then in C#? The converter gave me if (oStruct.AH_DATE != 1/1/1900 12:00:00 AM) { which is of course not correct but I cannot seem to work out how to make it correct.

  • Importing tab delimited file into array in Visual Basic 2013 [migrated]

    - by JaceG
    I am needing to import a tab delimited text file that has 11 columns and an unknown number of rows (always minimum 3 rows). I would like to import this text file as an array and be able to call data from it as needed, throughout my project. And then, to make things more difficult, I need to replace items in the array, and even add more rows to it as the project goes on (all at runtime). Hopefully someone can suggest code corrections or useful methods. I'm hoping to use something like the array style sMyStrings(3,2), which I believe would be the easiest way to control my data. Any help is gladly appreciated, and worthy of a slab of beer. Here's the coding I have so far: Imports System.IO Imports Microsoft.VisualBasic.FileIO Public Class Main Dim strReadLine As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim sReader As IO.StreamReader = Nothing Dim sRawString As String = Nothing Dim sMyStrings() As String = Nothing Dim intCount As Integer = -1 Dim intFullLoop As Integer = 0 If IO.File.Exists("C:\MyProject\Hardware.txt") Then ' Make sure the file exists sReader = New IO.StreamReader("C:\MyProject\Hardware.txt") Else MsgBox("File doesn't exist.", MsgBoxStyle.Critical, "Error") End End If Do While sReader.Peek >= 0 ' Make sure you can read beyond the current position sRawString = sReader.ReadLine() ' Read the current line sMyStrings = sRawString.Split(New Char() {Chr(9)}) ' Separate values and store in a string array For Each s As String In sMyStrings ' Loop through the string array intCount = intCount + 1 ' Increment If TextBox1.Text <> "" Then TextBox1.Text = TextBox1.Text & vbCrLf ' Add line feed TextBox1.Text = TextBox1.Text & s ' Add line to debug textbox If intFullLoop > 14 And intCount > -1 And CBool((intCount - 0) / 11 Mod 0) Then cmbSelectHinge.Items.Add(sMyStrings(intCount)) End If Next intCount = -1 intFullLoop = intFullLoop + 1 Loop End Sub

  • Simple alternating text in Visual Basic 2008

    - by Josh Grate
    I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

  • Is there a recommended approach for using SQL Server as an Authorization store and extending AD properties using .Net? [closed]

    - by Jim
    We are going to be using SQL Server as an authorization store for our .Net windows services and WCF services as well as storing additional metadata about users and groups to extend the AD properties. Doing this will make this self service and not require IT to change anything for our department (for users or groups). What if any are the existing recommended stategies or technologies that do this function?

  • IIS 7.5 Basic authorization issue

    - by Alsin
    When I log on using correct user name\password (I always copy-paste them) I get 401.1 error. User name and password are correct (user is created on server locally, not a domain one). I can run program as this user (runas /noprofile /user:tmp notepad.exe). Basic authorization's default domain is a server name, realm is empty. I've saved FailedReqLogFile. AUTH_BASIC_LOGON_FAILED shows ErrorCode="Logon failure: unknown user name or bad password. (0x8007052e)" and MODULE_SET_RESPONSE_ERROR_STATUS shows ModuleName="BasicAuthenticationModule", Notification="AUTHENTICATE_REQUEST", HttpStatus="401", HttpReason="Unauthorized", HttpSubStatus="1", ErrorCode="Logon failure: unknown user name or bad password. (0x8007052e)", ConfigExceptionInfo="" And one more thing - if I use my domain login\password it woks! Basic Authentications is only enabled authentication in application... Could you please suggest me how I can troubleshoot and fix this issue? Maybe somebody hit it before... Best regards, Alex UPDATE: I get 401.1 when I trying to access site from local host. I can actually access files from remote host.

  • OEG11gR2 integration with OES11gR2 Authorization with condition

    - by pgoutin
    Introduction This OES use-case has been defined originally by Subbu Devulapalli (http://accessmanagement.wordpress.com/).  Based on this OES museum use-case, I have developed the OEG11gR2 policy able to deal with the OES authorization with condition. From an OEG point of view, the way to deal with OES condition is to provide with the OES request some Environmental / Context Attributes.   Museum Use-Case  All painting in the museum have security sensors, an alarm goes off when a person comes too close a painting. The employee designated for maintenance needs to use their ID and disable the alarm before maintenance. You are the Security Administrator for the museum and you have been tasked with creating authorization policies to manage authorization for different paintings. Your first task is to understand how paintings are organized. Asking around, you are surprised to see that there isno formal process in place, so you need to start from scratch. the museum tracks the following attributes for each painting 1. Name of the work 2. Painter 3. Condition (good/poor) 4. Cost You compile the list of paintings  Name of Painting  Painter  Paint Condition  Cost  Mona Lisa  Leonardo da Vinci  Good  100  Magi  Leonardo da Vinci  Poor  40  Starry Night  Vincent Van Gogh  Poor  75  Still Life  Vincent Van Gogh  Good  25 Being a software geek who doesn’t (yet) understand art, you feel that price(or insurance price) of a painting is the most important criteria. So you feel that based on years-of-experience employees can be tasked with maintaining different paintings. You decide that paintings worth over 50 cost should be only handled by employees with over 20 years of experience and employees with less than 10 years of experience should not handle any painting. Lets us start with policy modeling. All paintings have a common set of attributes and actions, so it will be good to have them under a single Resource Type. Based on this resource type we will create the actual resources. So our high level model is: 1) Resource Type: Painting which has action manage and the following four attributes a) Name of the work b) Painter c) Condition (good/poor) d) Cost 2) To keep things simple lets use painting name for Resource name (in real world you will try to use some identifier which is unique, because in future we may end up with more than one painting which has the same name.) 3) Create Resources based on the previous table 4) Create an identity attribute Experience (Integer) 5) Create the following authorization policies a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience OES Authorization Configuration We do need to create 2 authorization policies with specific conditions a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience We don’t need an explicit policy for Deny access to all paintings for employees with less than 10 year of experience, because Oracle Entitlements Server will automatically deny if there is no matching policy. OEG Policy The OEG policy looks like the following The 11g Authorization filter configuration is similar to :  The ${PAINTING_NAME} and ${USER_EXPERIENCE} variables are initialized by the "Retrieve from the HTTP header" filters for testing purpose. That's to say, under Service Explorer, we need to provide 2 attributes "Experience" & "Painting" following the OES 11g Authorization filter described above.

  • Custom fine-grained claims based authorization system in ASP.NET MVC - wheres and hows

    - by BuzzBubba
    So, I'd like to implement my own custom authorization system in MVC2. If I'd have to create a global class, where do I instantiate it? Can HttpContext be extended with my own additions and where do I do that? Should I use Authorization filters for rights validation or ActionFilters or do it within an action? Can ActionFilter pass any data to the action itself? Previously (in WebForms) I was using a Session object where I would put a serialized object containing essential user data (account id and a list of roles and rights) and I'd extend my own Page class.

  • Rails authorization plugins

    - by jacklin
    We are evaluating plugins for Authorization in Rails. The two at the top of our list are cancan and declarative_authorization. I would like to get some feedback from anyone currently using either of these plugins. The problem we are going to face with any authorization plugin is that we have a database per customer model and will need to modify the plugin to work within that model. Because of this fact I'm interested in hearing from anyone who has had to tweak the plugins at all as well. I'm just starting to look around at the code. It seems like cancan might be a little easier to customize. Any thoughts?

  • Token based Authentication for WCF HTTP/REST Services: Authorization

    - by Your DisplayName here!
    In the previous post I showed how token based authentication can be implemented for WCF HTTP based services. Authentication is the process of finding out who the user is – this includes anonymous users. Then it is up to the service to decide under which circumstances the client has access to the service as a whole or individual operations. This is called authorization. By default – my framework does not allow anonymous users and will deny access right in the service authorization manager. You can however turn anonymous access on – that means technically, that instead of denying access, an anonymous principal is placed on Thread.CurrentPrincipal. You can flip that switch in the configuration class that you can pass into the service host/factory. var configuration = new WebTokenWebServiceHostConfiguration {     AllowAnonymousAccess = true }; But this is not enough, in addition you also need to decorate the individual operations to allow anonymous access as well, e.g.: [AllowAnonymousAccess] public string GetInfo() {     ... } Inside these operations you might have an authenticated or an anonymous principal on Thread.CurrentPrincipal, and it is up to your code to decide what to do. Side note: Being a security guy, I like this opt-in approach to anonymous access much better that all those opt-out approaches out there (like the Authorize attribute – or this.). Claims-based Authorization Since there is a ClaimsPrincipal available, you can use the standard WIF claims authorization manager infrastructure – either declaratively via ClaimsPrincipalPermission or programmatically (see also here). [ClaimsPrincipalPermission(SecurityAction.Demand,     Resource = "Claims",     Operation = "View")] public ViewClaims GetClientIdentity() {     return new ServiceLogic().GetClaims(); }   In addition you can also turn off per-request authorization (see here for background) via the config and just use the “domain specific” instrumentation. While the code is not 100% done – you can download the current solution here. HTH (Wanna learn more about federation, WIF, claims, tokens etc.? Click here.)

  • web.config + asp.net MVC + location > system.web > authorization + Integrated Security

    - by vdh_ant
    Hi guys I have an ASP.Net MVC app using Integrated Security that I need to be able grant open access to a specific route. The route in question is '~/Agreements/Upload' and the config I have setup looks like this: <configuration> ... <location path="~/Agreements/Upload"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> ... </configuration> I have tried a few things and nothing has worked thus far. In IIS under Directory Security Authentication Methods I only have "Integrated Windows Authentication" selected. Now this could be part of my problem (as even though IIS allows the above IIS doesn't). But if that's the case how do I configure it so that Integrated Security works but allows people who aren't authenticated to access the given route. Cheers Anthony

  • Basic Auth on DirectoryIndex Only

    - by Brad
    I am trying to configure basic auth for my index file, and only my index file. I have configured it like so: <Files index.htm> Order allow,deny Allow from all AuthType Basic AuthName "Some Auth" AuthUserFile "C:/path/to/my/.htpasswd" Require valid-user </Files> When I visit the page, 401 Authorization Required is returned as expected, but the browser doesn't prompt for the username/password. Some further inspection has revealed that Apache is not sending the WWW-Authenticate header. GET http://myhost/ HTTP/1.1 Host: myhost Connection: keep-alive User-Agent: Mozilla/5.0 (Windows NT 5.1) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.100 Safari/534.30 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 HTTP/1.1 401 Authorization Required Date: Tue, 21 Jun 2011 21:36:48 GMT Server: Apache/2.2.16 (Win32) Content-Length: 401 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>401 Authorization Required</title> </head><body> <h1>Authorization Required</h1> <p>This server could not verify that you are authorized to access the document requested. Either you supplied the wrong credentials (e.g., bad password), or your browser doesn't understand how to supply the credentials required.</p> </body></html> Why is Apache doing this? How can I configure it to send that header appropriately? It is worth noting that this exact same set of directives work fine if I set them for a whole directory. It is only when I configure them to a directory index that they do not work. This is how I know my .htpasswd and such are fine. I am using Apache 2.2 on Windows. On another note, I found this listed as a bug in Apache 1.3. This leads me to believe that this is actually a configuration problem on my end.

  • Should BASIC continue to be recommended for non-programmers and beginners?

    - by Casey
    I just came across a new BASIC implementation for Google Android application called Simple. You can read about it here: http://google-opensource.blogspot.com/2009/07/programming-made-simple.html Clearly, a lot of time and effort has been recently put into enabling this functionality for Android. Should the software industry continue to encourage non-programmers into learning BASIC, or are modern languages like C#, Python, Ruby more appropriate at this time?
