Authenticate PDF passwords remotely

When user enters password for a PDF file can those password be authenticated remotely, by calling some web service ?

This can be accomplished with Digital Rights Management. This is quite costly are requires a server. Think 5 to 6 figures and per use fees. You can check out The LiveCycle Suite of Products if you want more information.

  • Mac os x wiki server can't authenticate user password from active directory recently after we upgraded to windows 2008 server.

    after upgraded to windows 2008 server, our  mac os x wiki server can't authenticate user password anymore. How can I re-bind the wiki server to the AD again? thanks in advance.

    Solved it by deleting the user and creating a new one with the same userID.
    Maybe it occured because I marked the "user has to change password after first login" box when resetting the password but didn't yet allow him to do so in the webpages menu?!?

  • I cannot open PDF files in Photoshop Elements as it is asking for a PDF Password?

    I cannot open PDF files in Photoshop Elements as it is asking for a PDF Password?

    Is it possible that the creator of the files set a password? That's usually the only time PSE asks for one, although you may be able to open the file just fine in a pdf program that isn't password-aware.

  • PDF password

    I know i must be thick, but can anyone out there in the real world please tell my how on god's earth do i find a stupid PDF password so i can open a simple file that after 3 months of trying it MAY! be able to assist me in doing the most simplest of task's? I bought a Canon 5d II from a guy and he is registered as the author and HIS name comes up as copywrite of my work, and all i want to do is go on line and change it over into my name. So Canon has given me some info on what to download, but guess what? I can't open it because i need a PDF password. I did'nt get a disc with the camera, and adobe can't help me because there are no real people out there to talk to, and YES! i am VERY FRUSTRATED.
    Can anyone PLEASE, PLEASE, PLEASE HELP.

    Eddy,
    As this appears to be the same problem, posted in this Ps General Discussions thread: http://forums.adobe.com/message/6151131#6151131
    I will Lock this duplicate post, so that all discussion can continue in that other thread, to avoid much confusion. It is also a very good idea to ONLY post of a single problem once. You might have to be patient, until a user comes along with help, but that is the nature of the Adobe Forums - they are mostly user-to-user.
    Good luck,

  • AirPrint and pdf password protected file issue

    Hello
    I'm facing issue while printing pdf password protected file via Airprint.
    From my iPhone /iPad I can print without any issue to my HP dj 2540 almost everything except pdf password protected file.
    The same pdf file (protected with password) can be printed without any issue form any PC/laptop.
    Do anyone have any idea on how to solve this issue, please?
    Thanks
    regards
    Michele

    It seems that everyone asking this question have links from Grand Canyon University which will soon have over a 100,000 online students that all use ebooks that open just fine in Adobe Acrobat on their PCs BUT NOT on the mobile versions of Adobe Acrobat. Whatever allows this on PCs needs to be added to the mobile version soon.  We rely on our etextbooks that can ONLY be opened on the PC version of Acrobat.  That is ridiculous.  I can't believe with all the posts regarding password protected ebooks on this forum....that it hasn't been resolved.  No one can give you a link because the ebooks are on a website that needs a password.  We can save the books to our harddrives/dropbox...  I could send you a copy, but thats it.  Surely someone at Adobe knows what the hell is going on and can test the problem out themselves?

  • What is a PDF password?

    What is  PDF password and  how do I generate one?  I try to open a PDF photo file in Elements 11 and it says I need a password.  I have no idea what this is.

    You don't need to generate one. The person who created the PDF set it up to require a password to open it. You will need to contact whoever created it to get the password in order to view it.

  • How robust is PDF-Password protection? Does it also work for PDF/A?

    Several sources say that PDF passwords can be removed with appropriate software. Is this true?
    Can I also protect a PDF/A with a password? If not, how can I be sure that I can still open a regular password protected PDF in 10 years from now?
    Many thanks.

    Actually PDF/A is specifically designed to guarantee that the documents can be read in the distant future (barring global destruction, end of reality as we know it, alien sheep invasions, etc.)
    While we cannot predict which vendor will be providing the software to do it, or how the data will be stored by then (holographic data mice are still in beta) the PDF/A standard is designed to do two very important things:
    The standard is open, so the structure of a PDF/A file can be interpreted by anyone who can open it and compare the contents to the standard (which itself is also published in PDF/A). It's basically a text file with lots of symbols in it.
    PDF/A forbids any encryption or licensed algorithms (e.g. H.264) that could be impossible or illegal for a future viewer to use, for example if a password is lost or the inventor of a proprietary algorithm goes crazy and cancels all the licenses.
    Combined, these points make PDF/A impossible not to be parsable. It may end up projected directly into your brain by the aforementioned holographic data mouse, but you'll be reading it all the same.

    As to your ability to open a secured password in 20 years from now? Heck there is no guarantee that your non-secured pdf file will be readable in 20 years. With PDF/A your chances are pretty good as it uses standards based file format, but there is no guarentee that Adobe or any other company doing business today will be in business 20 years from now.

  • How can I remove PDF password?

    Hi guys, recently I've got a really annoying problem at work. Some of my PDFs can not be copyed, edited or printed. I know that's because they're secured but how can I remove the password? Any idea to work out the problem?

    Hello,
    As there is no any C# solution ,I would like to psot some sample codes to achieve this.
    using Spire.Pdf;
    using Spire.Pdf.Security;
    namespace modify_PDF_passwords
    class Program
    static void Main(string[] args)
    //load a encrypted file and decrypt it
    String encryptedPdf = @"..\Encrypt.pdf";
    PdfDocument doc = new PdfDocument(encryptedPdf, "e-iceblue");
    //reset PDF passwords and set user password permission
    doc.Security.OwnerPassword = "Spire.PDF";
    doc.Security.UserPassword = "pdfcomponent";
    doc.Security.Permissions = PdfPermissionsFlags.Print | PdfPermissionsFlags.FillFields;
    //Save pdf file.
    doc.SaveToFile("Encryption.pdf");
    doc.Close();
    //Launching the Pdf file.
    System.Diagnostics.Process.Start("Encryption.pdf");
    Anyway ,it is a PDF component based solution,which works pretty fine for me.

  • Adobe Acrobat Reader Crafted PDF Document Remote Code Execution

    Hi all,
    I was wondering if Adobe can clarify when "CVE-2012-4363 Adobe Acrobat Reader Crafted PDF Document Remote Code Execution" will be fixed?
    It's been a pretty long time since this issue was reported.
    With kind regards,
    Erik Verhoef
    The Netherlands

    i was also given the Knowledge Base number 405461 from adobe, and they said that this would definitely fix the problem...AND IT DIDN'T :-(
    see kb405461
    http://kb.adobe.com/selfservice/view...nalId=kb405461
    and just to let everyone know, i have already completely uninstalled adobe reader and reinstalled it several times thinking that fresh install would cure the problem, and it hasn't made a bit of difference. the version of reader doesn't matter either, as i've tried versions 7, 8 and 9... all with the same exact issue...which makes me think that it might be an issue with MS IE6.

  • Changing password remotely via passwd

    I need to change my password remotely via ssh on a machine running Leopard.  I know one can do this via the passwd command, but it used to be the case that it wouldn't also change the Keychain password.
    Do you know if passwd has ever been updated so that it also updates the Keychain password?

  • Acrobat Pro 9 SharePoint PDF Review Remote Service Authentication

    I am using Adobe Acrobat Pro Extended 9.4.3 (as part of the Technical Communication Suite 2.5). I am hosting PDF reviews on our company SharePoint server. In the past, I haven't had any problems doing this.
    However today I cannot connect, and a "Remote Service Authentication" dialog box (see below) appears everytime I try to connect to a PDF review. This is the same for both reviews I have started, or for reviews others have started. Also, I have full permissions for the SharePoint Document Library.
    I entered my credentials, then clicked OK. The dialog box just reappears over... and over... and over.
    It doesn't seem to matter which program the PDF documents were created with (same dialog for documents generated from MS Word and Framemaker). And a co-worker was able to connect without a problem and enter comments (of course, I can't see his comments since I cannot connect to the server). This leads me to believe that it is a problem on my machine.
    Any ideas?

    Yes, I initiated the review. When I initiated the review, I saw a different dialog for entering my username and password. That took my credentials and uploaded the PDF to SharePoint.
    I don't remember seeing RSA dialog (see the image I attached to the first post) when I created the review, only when I opened the PDF after the review was generated. At that point, I did select to save the credentials, but it didn't seem to save them (since everytime the dialog appears it is blank).
    I had another one of our tech writers test it before sending it to the rest of the team, and he was able to access the review and put in test comments. He never saw the dialog. At that point, I looked at other reviews that I had initiated in the past, and was unable to add comments to those either (at least for the ones that didn't have a deadline). So I am pretty sure it is something that has changed on my system in the last few weeks. Perhaps a Microsoft Security update?

  • How can I Change a User's password remotely

    Hi all
    I setup an iChat Server. I need to allow the users the ability to change their password without physically accessing the server (including via Remote Managment)
    Thow some iChat(jabber) Clients support changing the password, the iChat Server does not appear to have this option.
    Is there any way to remotely change a user's password ?
    A possible solution would be to setup a Webpage allowing the user to logon and change the Password.
    Is there any web managment tool on OS X Server for this ?
    Any other sugestions?
    Thanks,
    Best regards

    This is getting depressing. I've just speand most of a day getting the OID to support ldaps SSL protocol, since I read that a number of active directory services only allow password change if the connection is encrypted. Finally got my ldaps connection, but the NoPermissionException is still there. The user I'm signing on as is definitely has user security management permissions. I can't seem to modify attributes at all. I added my own optional attribute to the schema, but JNDI can't set it.
    Perhaps the oracle LDAP library in jpdk might help, but I'm not hopeful. If I could find any API documentation I might be more moved to try, but I see no setPassword methods in the relavant classes. This just looks like a fairly thin wrapper for JNDI anyway.
    Does anyone know where the API doc for oracle.ldap.* is? Has anyone got a password to change other than by the SSO's built in change password dialog?
    I'm not hopeful. On these boards I've found many questions along these lines but, thus far, no answers.

  • PDF password security greyed out while saving a PDF MP Navigator

    Hello,
    I am unable to set a password for pdf's that I scan with MP Navigator. I have been doing it for years, but now it has greyed out. It is not selectable. I recently upgraded my mobo and did a clean reinstall. The problem occurred before the upgrade and now remains despite full reinstalls of everything. The preferences button provides no way to turn passwords on or off. The Set... button shows password security also greyed out.
    Win 7 Home premium 64 bit, 8GB, 250GB SSD root drive, Core i7. MP navigator EX 5.1. Pixma MP 895.
    Thanks,
    Jim

    A simple way is to flatten the form fields, which converts the field appearances to regular page contents. You can do this with JavaScript or PDF Optimizer (Advanced > PDF Optimizer > Discard Objects > Flatten form fields). A very nice script that adds a custom menu item can be found here: http://www.uvsar.com/projects/acrobat/flattener/

  • Preview/Adobe PDF password protection issue

    I have a pdf file that is password protected to be able to view the content. The protection works as it should in Adobe Reader. However, when I open the file in Preview I can see the first page, but the rest are unviewable. The page thumbnail on the right is just a placeholder, not an actual thumbnail and when you navigate to those pages the actual page appears as a ? in a box.
    Any suggestions as to what is going on or how to make this work properly?

    Just to register that it seems to be really a problem with Preview. I had a similar problem too. I had a secure PDF (no doc assembly, no page extraction, no commenting, no filling form, no signing, no creation of template pages) and it opens as expected in Acrobat Reader 9, but in Preview, all pages ate blank, and the thumbs are absent, with only the first page being seen as a blank one. I tried to open it in Acrobat Reader 8 and it says that it couldn't open the document because it couldn't decrypt it. I guess that Acrobat 9 has some new encryption scheme that is incompatible with previous versions, including Apple's Preview.
    I'd like to know if a fix for this is planned.
    Thanks a lot!
