• Using db4o with multiple application instances under medium trust

  - by Anders Fjeldstad

  I recently stumbled over the object database engine db4o which I think looks really interesting. I would like to use it in an ASP.NET MVC application that will be deployed to a shared hosting environment under medium trust. Because of the trust level, I'm restricted to using db4o in embedded/in-process mode. That in itself should be no problem, but the hosting provider also transparently runs each web application in multiple (load-balanced) server instances with shared storage, which I would say is normally a very nice feature for a $10/month hoster. However, since an instance of a db4o server with write access (whether in-process or networked) locks the underlying database file, having multiple instances of the application using the same file won't work (or at least I can't see how it would). So the question is: is it possible to use db4o in this specific environment? I have considered letting each application have its own database which is synchronized with a master database using replication (dRS), but that approach will most likely end up with very frequent bi-directional replication (read master changes at beginning of each request, write to master after each change) which I don't think will be very efficient. Summary of the web application/environment characteristics: Read-intensive (but not entirely read-only) Some delay (a few seconds) is acceptible between the time that a change is made and the time when the change shows up in all the application instances' data Must run in medium trust No guarantee that the load-balancer uses "sticky sessions" All suggestions are much appreciated!

• Trust my work domain on a Dev Domain without a domain level password

  - by Vaccano

  I setup a virtual machine to host a dev version of TFS (to test plugins on). Getting a computer on my work domain requires large amounts of red tape and paperwork that I would rather not do. I created my own domain the the VM and I would like to trust all users from my work domain on that VM Domain. But when I tried to setup the trust I needed a password from my work domain (which I don't have). Am I trying to do something nefarious? I just want to be able to authenticate to my Test TFS (VM) Server as me (my login on my work domain). Is there a way to do that with out having to have a domain level password for my work domain? (My VM is a Windows Server 2008 R2 server)

• One-way forest trust between geographically distributed forests using Server 2008 R2

  - by bwerks

  Hi all, I'm planning out a joinder between two domains, as would take place with contracting companies. Forests A and B exist in distant sites, and there is to be a one-way forest trust so that domain users in Forest A can be authenticated on machines in Forest B. In order to facilitate this, each forest's domain controller must be able to contact each other in order to set up & confirm the trust, but my question is what underlying networking magic must take place beneath it. So far the prevailing approach has been to maintain a VPN connection between the two sites, but the technet documentation seems to indicate that DNS forwarding may be the way to go. Is this the case? Furthermore, if DNS will suffice, does that mean that there must be a server running DNS on boundary servers in each domain so that they can be reached from across the internet? How must they be configured? Thanks!

• Cross-Forest Trust

  - by cdalley

  I am looking at testing a cross-domain trust we can have two domain controllers (with different forests and domain names) setup so we can move everyone onto the new domain. We do NOT run exchange on site and we do not have any links to O365 to AD currently. Onto the problem: I have setup two DCs in a Virtual Machine: They are on the same network 192.168.0.* The Windows 2003 server: Name: OLDSRVR "Clone" of our current Domain Controller IP: 192.168.0.1 Domain: internal.test.com The Windows 2012 server: Name: ADCTEST01 Brand new domain setup from scratch separate to internal.test.com Domain: internal.test2.com IP: 192.168.0.2 OLDSRVR can only see ADCTEST if it has dynamic IP set. If I set a static IP it cannot see it. If I try using the dynamic IP and try to join it gets to the end then complains "??The trust relationship between this workstation and the primary domain failed" Any ideas?

• Entity Framework - Medium Trust

  - by Echilon

  I'm trying to get the entity framework working in medium trust. I've tried splitting the files and using a separate assembly but I seem to have one problem after another. I moved the EDMX to a separate assembly, which causes a single .dll to be outpit to the sites /Bin directory. I'm referencing this as below from web.config. Whenever I try to access one of the entity classes, I get an ArgumentException: 'An item with the same key has already been added.' It's critical this works with medium trust, but I seem to be running out of options. Any advice greatly appreciated.

• Which IOC runs in medium trust

  - by Rippo

  Hi I am trying to get a website running with Mosso that has Castle Windsor as my IOC, however I am getting the following error. [SecurityException: That assembly does not allow partially trusted callers.] GoldMine.WindsorControllerFactory..ctor() in WindsorControllerFactory.cs:33 GoldMine.MvcApplication.Application_Start() in Global.asax.cs:70 My questions are Does Castle Windsor run under medium trust? Can I download the DLL's without having to recompile with nant? (as I don't have this set up and don't know nant at all) Or is there another IOC that I can use that I can download and works in Medium Trust? Thanks

  Did somebody already make a two-way trust relationship between Samba 3 and AD ? I've got Samba 3.5 domain (ES02) controller and AD 2008 R2 domain (ES01) controller. Trust domain seems to be ok: Trusted domains list: ES01 S-1-5-21-1816646249-803782145-3669927669 Trusting domains list: ES01 S-1-5-21-1816646249-803782145-3669927669 I can login AD domain workstation with a Samba user account and access to AD domain workstation shares from Samba workstation with Samba user account.

• ASP.Net Application Trust Medium File IO Outside Virtual Directory

  - by Trey Gramann

  I am trying to determine how suicidal this is... I have a hosting environment where a custom ASP.Net CMS application needs to access the files in the root folder of a website even though it is in a virtual folder so it can be shared accross many sites. I can modify the Medium trust on the server and came up with this... <IPermission class="FileIOPermission" version="1" Read="$AppDir$;$AppDir$\.." Write="$AppDir$;$AppDir$\.." Append="$AppDir$;$AppDir$\.." PathDiscovery="$AppDir$;$AppDir$\.."/> Oddly enough, it works. Yes, I understand it is doing this for all the Apps. I am a bit at a loss as to easy ways to test what else is being exposed. Feels dangerous. Opinions?

• Trust metrics and related algorithms

  - by Nick Gerakines

  I'm trying to learn more about trust metrics (including related algorithms) and how user voting, ranking and rating systems can be wired to stiffle abuse. I've read abstract articles and papers describing trust metrics but haven't seen any actual implementations. My goal is to create a system that allows users to vote on other users and the content of other users and with those votes and related meta-data, determine if those votes can be applied to a users level or popularity. Have you used or seen some sort of trust system within a social graph? How did it work and what were its areas of strength and weaknesses?

• How can Hosting Providers allow .NET Full Trust?

  - by Alex

  I wondered how certain .NET hosting providers can safely grant full trust to their customers? Doesn't this open up everybody who is hosting with that company to potential safety issues? Or is there a way to safely restrict each customer, despite giving full trust, to "their" space without giving them the abiliy to bring down the system or spy on other customers?

• Partial Trust in WPF 4

  - by Hadi Eskandari

  I've started a new project in WPF 4 (.NET 4) and trying to see if I can run it in xbap mode. I need to run the application in Full Trust with the new mode made available in .NET 4 which asks the end user if the full trust application should be run.

• SQL Azure and Trust Services

  - by BuckWoody

  Microsoft is working on a new Windows Azure service called “Trust Services”. Trust Services takes a certificate you upload and uses it to encrypt and decrypt sensitive data in the cloud. Of course, like any security service, there’s a bit more to it than that. I’ll give you a quick overview of how you can use this product to protect data you send to SQL Azure. The primary issue with storing data in the cloud is that you are in an environment that isn’t under your control – in fact, that’s the benefit of being in a distributed computing environment in the first place. On premises you’re able to encrypt data you don’t want anyone else to see, using various methods such as passwords (not very strong) or certificates (stronger). When you use a certificate, it’s vital that you create (or procure) and protect it yourself. When you store data remotely, regardless of IaaS, PaaS or SaaS, you don’t own the machines where the data lives. That means if you use a certificate from the cloud vendor to encrypt the data, you have to trust that the data won’t be accessed by the vendor. In some cases having a signed agreement with the vendor that they won’t access your data is sufficient, in other cases that doesn’t meet the requirements your system has for security. With the new Trust Services service, the basic process is that you use a Portal to create a Trust Server using policies and other controls. You place a X.509 Certificate you create or procure in that server. Using the Software development Kit (SDK), the developer has access to an Application Layer Encryption Framework to set fields of data they want to encrypt. From there, the data can be stored in SQL Azure as a standard field – only it is encrypted before it ever arrives. The portion of the client software that decrypts the data uses the same service, so the authenticated user sees the data if they are allowed to do so. The data remains encrypted “at rest”.  You can learn more about this product and check it out in the SQL Azure labs at Microsoft Codename "Trust Services"

• Helvetica Neue font defaults to medium instead of regular

  - by teppic

  I've installed the set of Helvetica Neue truetype fonts in my ~/.fonts directory, and they all show up correctly with fc-list. However, if an application selects the standard font, it's returning the medium style instead of the regular, e.g.: $ fc-match "Helvetica Neue" HelveticaNeueMedium.ttf: "Helvetica Neue" "??" If I remove the medium font from the system, it gets the correct one: $ fc-match "Helvetica Neue" HelveticaNeue.ttf: "Helvetica Neue" "???" I'm sure this can be corrected in fonts.conf, but what's the entry required? The only workaround I have right now is to remove the medium style as above, but this means I can't access it at all.

• Clickonce intranet application trust

  - by Mark

  Hi, we have a VSTO outlook add-in we'd like to silently deploy to everyone via AD. I'm signing the App with a "Code signing" certificate (requested certmgr from AD). If I add this certificate to my Trusted Publishers, then I can silently install the signed app via the VSTOInstaller.exe (with the /S switch). We don't want to have to install my certificate as a trusted publisher on everyone's machine - we'd like to be able to say that any code signed by a certificate issued within our AD is trusted. Is there some way to do this?

• Create a Social Community of Trust Along With Your Federal Digital Services Governance

  - by TedMcLaughlan

  The Digital Services Governance Recommendations were recently released, supporting the US Federal Government's Digital Government Strategy Milestone Action #4.2 to establish agency-wide governance structures for developing and delivering digital services. Figure 1 - From: "Digital Services Governance Recommendations" While extremely important from a policy and procedure perspective within an Agency's information management and communications enterprise, these recommendations only very lightly reference perhaps the most important success enabler - the "Trusted Community" required for ultimate usefulness of the services delivered. By "ultimate usefulness", I mean the collection of public, transparent properties around government information and digital services that include social trust and validation, social reach, expert respect, and comparative, standard measures of relative value. In other words, do the digital services meet expectations of the public, social media ecosystem (people AND machines)? A rigid governance framework, controlling by rules, policies and roles the creation and dissemination of digital services may meet the expectations of direct end-users and most stakeholders - including the agency information stewards and security officers. All others who may share comments about the services, write about them, swap or review extracts, repackage, visualize or otherwise repurpose the output for use in entirely unanticipated, social ways - these "stakeholders" will not be governed, but may observe guidance generated by a "Trusted Community". As recognized members of the trusted community, these stakeholders may ultimately define the right scope and detail of governance that all other users might observe, promoting and refining the usefulness of the government product as the social ecosystem expects. So, as part of an agency-centric governance framework, it's advised that a flexible governance model be created for stewarding a "Community of Trust" around the digital services. The first steps follow the approach outlined in the Recommendations: Step 1: Gather a Core Team In addition to the roles and responsibilities described, perhaps a set of characteristics and responsibilities can be developed for the "Trusted Community Steward/Advocate" - i.e. a person or team who (a) are entirely cognizant of and respected within the external social media communities, and (b) are trusted both within the agency and outside as practical, responsible, non-partisan communicators of useful information. The may seem like a standard Agency PR/Outreach team role - but often an agency or stakeholder subject matter expert with a public, active social persona works even better. Step 2: Assess What You Have In addition to existing, agency or stakeholder decision-making bodies and assets, it's important to take a PR/Marketing view of the social ecosystem. How visible are the services across the social channels utilized by current or desired constituents of your agency? What's the online reputation of your agency and perhaps the service(s)? Is Search Engine Optimization (SEO) a facet of external communications/publishing lifecycles? Who are the public champions, instigators, value-adders for the digital services, or perhaps just influential "communicators" (i.e. with no stake in the game)? You're essentially assessing your market and social presence, and identifying the actors (including your own agency employees) in the existing community of trust. Step 3: Determine What You Want The evolving Community of Trust will most readily absorb, support and provide feedback regarding "Core Principles" (Element B of the "six essential elements of a digital services governance structure") shared by your Agency, and obviously play a large, though probably very unstructured part in Element D "Stakeholder Input and Participation". Plan for this, and seek input from the social media community with respect to performance metrics - these should be geared around the outcome and growth of the trusted communities actions. How big and active is this community? What's the influential reach of this community with respect to particular messaging or campaigns generated by the Agency? What's the referral rate TO your digital services, FROM channels owned or operated by members of this community? (this requires governance with respect to content generation inclusive of "markers" or "tags"). At this point, while your Agency proceeds with steps 4 ("Build/Validate the Governance Structure") and 5 ("Share, Review, Upgrade"), the Community of Trust might as well just get going, and start adding value and usefulness to the existing conversations, existing data services - loosely though directionally-stewarded by your trusted advocate(s). Why is this an "Enterprise Architecture" topic? Because it's increasingly apparent that a Public Service "Enterprise" is not wholly contained within Agency facilities, firewalls and job titles - it's also manifested in actual, perceived or representative forms outside the walls, on the social Internet. An Agency's EA model and resulting investments both facilitate and are impacted by the "Social Enterprise". At Oracle, we're very active both within our Enterprise and outside, helping foster social architectures that enable truly useful public services, digital or otherwise.

• Ubuntu impossible to install: "unable to find a medium containing a live filesystem"

  - by Lorenzo

  Yes, I have read questions and answers with similar titles for this issue, which prevented me from installing Ubuntu for several MONTHS now, trying to figure it out. I have a MacBookPro with triple partition (one for Mac Snow Leopard, one for Windows 7, one for Linux) created with reFIT firmware (not BootCamp). I set up the system according to these instructions for reFIT: http://lifehacker.com/5531037/how-to-triple+boot-your-mac-with-windows-and-linux-no-boot-camp-required Now. There is a free partition ready to accept Linux into its arms, but Linux does not want to participate. Most answers to the issue "unable to find a medium containing a live filesystem" point to changing the BIOS booting system (which I don't know how to do, especially using this reFIT booting system), and to changing the socket of the USB (which does not concern me, since I am using a CD, actually I tried with a CD, then with a DVD, since a blank CD is only 700MB while the iso image file of Ubuntu is about 731MB). Anyway. This is what happens: I am in the Mac system (using the Mac partition) I insert the DVD with the burned image of Ubuntu (yes I have tried burning it again and agin on both CD and DVD blank discs). I restart the computer. When reFIT loads, I hold down the ALT key until the CD image appears. I select it, and hit Enter. A small Ubuntu icon appears at the bottom of the screen. Then a Ubuntu sign appears in the middle of the screen with small dots underneath, lighting up progressively over and over to indicate it's loading. Then everything turns black and the following message appears, at the end of a few lines of text: "unable to find medium with live file system". Please provide very practical suggestions on what to do to an unexperienced wannabe Ubuntu very patient user. Please start by saying how do I access the BIOS setup from reFIT bootup, and exactly what and why I need to try and change. (Will this mess up my reFIT bootup?) And anything else I need to do to finally be able to install Ubuntu. Thanks

• ADFS v.2.0 transitive trust in a federation scenario

  - by masi

  Currently i'm working with ADFS to establish a federated trust between two separated domains. My question is simple: does ADFS v. 2.0 support transitive trust across federated identity providers? I know that ADFS v 1.0 does not, as stated in this document on page 9. But when looking on the claims rules that come with ADFS 2.0 it seems to be possible, as a Microsoft partner confirmed. However: the documentation on this topic is a mess! Simply no ADFS v. 2.0 related statements on this topic that i was able to find (IF you got any documentation on this PLEASE help me out guys!). To be more clear, lets assume this scenario: Federation provider (A) trust federation provider (B) which trusts identity provider (C). So, does (A) trust identities comming from (C) across (B)? Also, if it is possible there are some things that i'm specially interested in: Is it possible to restrict the transitive trust in ADFS in any way? If so, how? How does the transitive trust affect the Issuer and OriginalIssuer properties of the claims? If transitive trust is used together with claims transformations and provider (B) would transform incomming claims from (C) in a way that they are transformed into (new) claims of same type an value, how would this affect the Issuer and OriginalIssuer properties?

Trying to get this process to finish, I found that the Ubuntu software center progress tab display a message reading: Applying Changes: Waiting for required medium What in the world does that mean and how can I get it to move on?

• Establishing WebLogic Server HTTPS Trust of IIS Using a Microsoft Local Certificate Authority

  - by user647124

  Everyone agrees that self-signed and demo certificates for SSL and HTTPS should never be used in production and preferred not to be used elsewhere. Most self-signed and demo certificates are provided by vendors with the intention that they are used only to integrate within the same environment. In a vendor’s perfect world all application servers in a given enterprise are from the same vendor, which makes this lack of interoperability in a non-production environment an advantage. For us working in the real world, where not only do we not use a single vendor everywhere but have to make do with self-signed certificates for all but production, testing HTTPS between an IIS ASP.NET service provider and a WebLogic J2EE consumer application can be very frustrating to set up. It was for me, especially having found many blogs and discussion threads where various solutions were described but did not quite work and were all mostly similar but just a little bit different. To save both you and my future (who always seems to forget the hardest-won lessons) all of the pain and suffering, I am recording the steps that finally worked here for reference and sanity. How You Know You Need This The first cold clutches of dread that tells you it is going to be a long day is when you attempt to a WSDL published by IIS in WebLogic over HTTPS and you see the following: <Jul 30, 2012 2:51:31 PM EDT> <Warning> <Security> <BEA-090477> <Certificate chain received from myserver.mydomain.com - 10.555.55.123 was not trusted causing SSL handshake failure.> weblogic.wsee.wsdl.WsdlException: Failed to read wsdl file from url due to -- javax.net.ssl.SSLKeyException: [Security:090477]Certificate chain received from myserver02.mydomain.com - 10.555.55.123 was not trusted causing SSL handshake failure. The above is what started a three day sojourn into searching for a solution. Even people who had solved it before would tell me how they did, and then shrug when I demonstrated that the steps did not end in the success they claimed I would experience. Rather than torture you with the details of everything I did that did not work, here is what finally did work. Export the Certificates from IE First, take the offending WSDL URL and paste it into IE (if you have an internal Microsoft CA, you have IE, even if you don’t use it in favor of some other browser). To state the semi-obvious, if you received the error above there is a certificate configured for the IIS host of the service and the SSL port has been configured properly. Otherwise there would be a different error, usually about the site not found or connection failed. Once the WSDL loads, to the right of the address bar there will be a lock icon. Click the lock and then click View Certificates in the resulting dialog (if you do not have a lock icon but do have a Certificate Error message, see http://support.microsoft.com/kb/931850 for steps to install the certificate then you can continue from the point of finding the lock icon). Figure 1: View Certificates in IE Next, select the Details tab in the resulting dialog Figure 2: Use Certificate Details to Export Certificate Click Copy to File, then Next, then select the Base-64 encoded option for the format Figure 3: Select the Base-64 encoded option for the format For the sake of simplicity, I choose to save this to the root of the WebLogic domain. It will work from anywhere, but later you will need to type in the full path rather than just the certificate name if you save it elsewhere. Figure 4: Browse to Save Location Figure 5: Save the Certificate to the Domain Root for Convenience This is the point where I ran into some confusion. Some articles mentioned exporting the entire chain of certificates. This supposedly works for some types of certificates, or if you have a few other tools and the time to learn them. For the SSL experts out there, they already have these tools, know how to use them well, and should not be wasting their time reading this article meant for folks who just want to get things wired up and back to unit testing and development. For the rest of us, the easiest way to make sure things will work is to just export all the links in the chain individually and let WebLogic Server worry about re-assembling them into a chain (which it does quite nicely). While perhaps not the most elegant solution, the multi-step process is easy to repeat and uses only tools that are immediately available and require no learning curve. So… Next, go to Tools then Internet Options then the Content tab and click Certificates. Go to the Trust Root Certificate Authorities tab and find the certificate root for your Microsoft CA cert (look for the Issuer of the certificate you exported earlier). Figure 6: Trusted Root Certification Authorities Tab Export this one the same way as before, with a different name Figure 7: Use a Unique Name for Each Certificate Repeat this once more for the Intermediate Certificate tab. Import the Certificates to the WebLogic Domain Now, open an command prompt, navigate to [WEBLOGIC_DOMAIN_ROOT]\bin and execute setDomainEnv. You should then be in the root of the domain. If not, CD to the domain root. Assuming you saved the certificate in the domain root, execute the following: keytool -importcert -alias [ALIAS-1] -trustcacerts -file [FULL PATH TO .CER 1] -keystore truststore.jks -storepass [PASSWORD] An example with the variables filled in is: keytool -importcert -alias IIS-1 -trustcacerts -file microsftcert.cer -keystore truststore.jks -storepass password After several lines out output you will be prompted with: Trust this certificate? [no]: The correct answer is ‘yes’ (minus the quotes, of course). You’ll you know you were successful if the response is: Certificate was added to keystore If not, check your typing, as that is generally the source of an error at this point. Repeat this for all three of the certificates you exported, changing the [ALIAS-1] and [FULL PATH TO .CER 1] value each time. For example: keytool -importcert -alias IIS-1 -trustcacerts -file microsftcert.cer -keystore truststore.jks -storepass password keytool -importcert -alias IIS-2 -trustcacerts -file microsftcertRoot.cer -keystore truststore.jks -storepass password keytool -importcert -alias IIS-3 -trustcacerts -file microsftcertIntermediate.cer -keystore truststore.jks -storepass password In the above we created a new JKS key store. You can re-use an existing one by changing the name of the JKS file to one you already have and change the password to the one that matches that JKS file. For the DemoTrust.jks  that is included with WebLogic the password is DemoTrustKeyStorePassPhrase. An example here would be: keytool -importcert -alias IIS-1 -trustcacerts -file microsoft.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase keytool -importcert -alias IIS-2 -trustcacerts -file microsoftRoot.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase keytool -importcert -alias IIS-2 -trustcacerts -file microsoftInter.cer -keystore DemoTrust.jks -storepass DemoTrustKeyStorePassPhrase Whichever keystore you use, you can check your work with: keytool -list -keystore truststore.jks -storepass password Where “truststore.jks” and “password” can be replaced appropriately if necessary. The output will look something like this: Figure 8: Output from keytool -list -keystore Update the WebLogic Keystore Configuration If you used an existing keystore rather than creating a new one, you can restart your WebLogic Server and skip the rest of this section. For those of us who created a new one because that is the instructions we found online… Next, we need to tell WebLogic to use the JKS file (truststore.jks) we just created. Log in to the WebLogic Server Administration Console and navigate to Servers > AdminServer > Configuration > Keystores. Scroll down to “Custom Trust Keystore:” and change the value to “truststore.jks” and the value of “Custom Trust Keystore Passphrase:” and “Confirm Custom Trust Keystore Passphrase:” to the password you used when earlier, then save your changes. You will get a nice message similar to the following: Figure 9: To Be Safe, Restart Anyways The “No restarts are necessary” is somewhat of an exaggeration. If you want to be able to use the keystore you may need restart the server(s). To save myself aggravation, I always do. Your mileage may vary. Conclusion That should get you there. If there are some erroneous steps included for your situation in particular, I will offer up a semi-apology as the process described above does not take long at all and if there is one step that could be dropped from it, is still much faster than trying to figure this out from other sources.

• Hot to get XChat to trust CA certificate?

  - by Silvio

  I have created an SSL certificate authority including a sub-authority to issue certificates. I have copied the root certificate to /usr/share/ca-certificates/extra and added it to /etc/ca-certificates, then ran dpkg-reconfigure ca-certificates and update-ca-certificates. After it said "Adding debian:.pem done." I am now fairly convinced that Ubuntu knows about my CA. Now I issued a certificate for the ZNC irc bouncer from the subca, installed it onto znc, but XChat will not trust the certificate despite all the above. I also issued a certificate to use with apache2 and that one works fine after adding the root ca to chromium. Does someone know how I can get XChat to trust the certificate?
