Http proxy authentication

hi
Could any body tell me how to connect to a resource outside
firewall.I know about the system properties namely httpProxyPort and
httpProxyHost.But can somebody tell me about the how to authenticate from the application.Note i am not using a browser based client.
Thanks in advance

can anyone tell me how to do proxy authetication if NTLM authorization is involved...i wrote a java client that is behind MS Proxy server and hence facing problem in establishing connection with sites...i am getting UnknownHost Exception when i try to call conn.connect() i think it's due to NTLM protocol..Can any one help me in this.
Thanks in advance

As I said before, while I've had OS 1.1.4, everything was normal. It began when I upgraded to 2.0.2 and after to 2.1. I also double checked if the TI here changed the policies, and they assured me they don't.
Several other users with 2.x are also reporting the same trouble. As far as now, I've came across a post suggesting me to install a local http proxy on the phone, but I don't think it's gonna work.
Let's keep this thread alive!

Http proxy authentication for JDev 10.1.3

Hi,
I found the http proxy settings in the "tools->preferences->Web Browser and Proxy" but there are no settings for the username and password. Is there some other way that I can add these.
The problem is that whenver JDeveloper wants to do some http stuff it (or something else is doing it) asks me for the proxy user name & password - this happens over and over again. If JDev is doing this then surely it should remember the username & password.
I sometimes get a JDeveloper dialog "waiting for the connection" come up over the proxy auth dialog and I have to cancel the function so I can authenticate, then re-request the function.
I wish I didn't have the proxy authentication but I have no choice in this dev environment. I do get to choose JDeveloper at least.
Regards,
Simon.

Hi,
I get it when I 'check for updates' and I get it again when I 'go to JavaDoc' - and this is the one where the "waiting for connection dialog" pops on top of the proxy log in and I have to cancel it to log in. Then all subsequent 'go to JavaDoc' requests go straight through.
I would prefer it if I could just configure (in proxy preferences) the username and password so it never asks me. I dont care if it less secure storing the password since I think authenticating proxies are a dumb idea anyway. If the password is not supplied then JDev can ask for it like it does now to keep the security-paranoid people happy.
Also, this morning I got this Exception which appeared at the same time I got a proxy auth window. When JDev finally started all my previously open windows were lost. No real problem but unexpected. Here is the stack dump:

WWSAPI - Cannot connect to web service via SSL and HTTP proxy authentication with NTLM, errorCode 0x803d0016, HTTP status 407

Hi,
I built a web service client using WWSAPI. The connection works via SSL (without HTTP proxy) and it works with SSL and proxy with basic authentication as well. When I try to connect using a proxy with NTLM authentication, then I get the errorCode
0x803d0016, HTTP status "407 (0x197)", "Proxy Authentication Required".
In WireShark I see only one HTTP request to connect to the proxy with NTLM Message Type: NTLMSSP_NEGOTIATE. The HTTP Response returns Status 407 and the connection ist closed. Comparing this to Internet Explorer - the Connection is not closed and
a second request with NTLMSSP_AUTH is sent.
Why doesn't it make the complete NTLM handshake? Why wasn't sent the NTLMSSP_AUTH directly?
I oriented in the HttpCalculatorWithKerberosOverSslClientExample.
Using WS_HTTP_HEADER_AUTH_SECURITY_BINDING,
WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_SCHEME was set to WS_HTTP_HEADER_AUTH_SCHEME_NTLM, WS_SECURITY_BINDING_PROPERTY_HTTP_HEADER_AUTH_TARGET to WS_HTTP_HEADER_AUTH_TARGET_PROXY. I tried WS_DEFAULT_WINDOWS_INTEGRATED_AUTH_CREDENTIAL_TYPE but also WS_STRING_WINDOWS_INTEGRATED_AUTH_CREDENTIAL_TYPE.
Any idea?
Thanks

Supressing the Browser HTTP Proxy Authentication Popup

Hi there.
I have an applet that does some socket proxying/tunnelling.
It has some code that detects whether the browser is connecting through a HTTP proxy and whether or not that proxy requires authentication.
When the code runs in a browser with a direct connection to the internet it is all good.
When the code runs in a browser with a standard HTTP Proxy connection to the internet it is all good.
But.. when it is connected through a HTTP Proxy that requires authentication I get a Java popup box asking for the Proxy's Username/Password.
See image here: http://peterdamen.com/JavaProxyPopup.png
I just want to suppress this popup. It pops up in the middle of a java routine, which suspends execution and then ruins javascript that communicates with the applet in the host HTML page.
Any ideas?
Thanks.
Peter

Did you ever get this figured out? I have the same issue. Thanks.

Https proxy authentication

I have a strange behaviour while browsing with Safari:
I'm located behind a proxy server which requires authentication. For all http requests, everything works perfect, at the first access ever, Safary asked me to supply username and pasword for the proxy, I've chosen to save the password in my key chain and was never asked again for the pasword.
For https requests, Safari asks at least one time per request to put in my proxy username and password. Sometimes, it seems that Safari asks for each single object on a web pagefor the proxy credentials.
I've tried to narrow down the effect and it seems, that this is related to WebKit. If I use Firefox, it asks me only once to put in the proxy credentials and that's it. With OmniWeb (which is also based on WebKit) I have the same problem as in Safari.
Has somebody got the same effect or even has a solution for that?
Thanks,
Frank
MacBook Pro Mac OS X (10.4.8) 15 inch, Core 2 Duo, 200GB HDD

I have the same problem:
I have to connect to a https url to post a string (and read the answer: OK or KO).
The problem is that I have to set up this with jdk 1.2, so:
- I download jsse 1.03
- I set up the provider statically inside java.security
(security.provider.2=com.sun.net.ssl.internal.ssl.Provider)
- I use the code:
System.setProperty("https.proxyHost","proxy");
System.setProperty("https.proxyPort","80");
System.setProperty("https.proxyUser","user");
System.setProperty("https.proxyPassword","password");
String password = "user:password";
String encodedLogin = new sun.misc.BASE64Encoder().encodeBuffer(password.getBytes());
System.setProperty("https.agent", "JSSE\n\rProxy-Authorization: "+encodedLogin+"\n\r");
URL url = new URL(urlString);
HttpsURLConnection connection = (HttpsURLConnection)url.openConnection();
connection.setRequestProperty("Proxy-Authorization", "Basic " + encodedLogin);
//connection.connect();
connection.setDoInput( true );
connection.setDoOutput( true );
connection.setAllowUserInteraction(false);
//URLConnection connection = new HttpsURLConnection(url);
InputStream inStream = connection.getInputStream();
When I call the getInputStream() I get the exception:
java.io.IOException: Unable to tunnel through XX.XY.ZX.WW:80. Proxy returns "HTTP/1.1 407 Proxy Access Denied
How can I authenticate to the proxy? The previos tips doesn't works ...
Any suggest?

IOS Global HTTP Proxy Authentication Error.

I have been attempting to use the HTTP Global Proxy feature on a group of iPads. Unfortunately, the proxy servers that I set up are starting to get spammed and we need to activate some form of authentication to avoid this problem. I have tried many methods and the result is always the same, the iPad keeps prompting the user for the username and password every few minutes, no matter how many times they have entered it correctly.
Is there any form of authentication that works smoothly? I am currently using Squid, but could use any other, and can run it on any OS that would make it work!

Here are the relevant parts of my squid config and some examples of what are in the acl files. I downloaded the ip list from ipdeny.com. As it was, the end of line character wasn’t correct and I had to correct that before squid would read it correctly. I just copied and pasted it into a new file to correct it.
I don’t know if this is the best way to approach this, and I am sure there are some problems with it currently. I am continuing to tweak it as things come up. With all allowed domains the number of authentication pop ups I received were drastically reduced. Looking it over I already see that rearranging the allow and deny rules would be of benefit for me.
I am also using fail2ban on this server with the squid configuration file from http://www.fail2ban.org/wiki/index.php/Fail2ban:Community_Portal#Squid_filter. This does eventually block someone who gets enough TCP_DENIED 407 messages. I also had modified it to include 403 messages with some success. The amount of blocks we receive from blocking ads I would get devices locked out unintentionally but increasing the number of attempts seems to have resolved this.

How to configure HTTP Proxy

I want XE to validate DTD references made in XML schema definitions. Metalink note 262708.1 refers to setting HTTP_PROXY environment variable/Registry value to do this through corporate firewalls.
Can I set this in XE? If so, how is it done on Windows XP?

OK, for the record I set the HTTP_PROXY value in HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_XE to
http://<username>:<password>@<http.proxy.server>:<port>
which seemed to do the trick as far as basic MS HTTP/proxy/authentication is concerned. The proxy software/configuration thereon is another matter...

Annoying Proxy authentication requests

In our lan we use Firefox (various versions, from 8 to 23, also 17 ESR releases) on windows computers (xp and 7 32 bit) . We require a http proxy authentication (squid) with username and password. We usually configure only Internet Options in windows control panel checking the flag on "use automatic configuration script" with an url like "http://proxy/proxy.pac". In this script we give a list of intranet sites (web applications) that don't require a proxy authentication on internet because are internal sites on our lan. So on firefox we use the option "Use system proxy settings". The issue is: during a session on those intranet sites the firefox dialog window for proxy authentication often appears annoying the operator who has to close it every time. We have tried to mitigate the problem disabling firefox automatic updates, add-ons updates, search engines updates, do not track requests, attack sites and web forgeries lists updates, telemetry, health and crash reports. It seems not to be enough to solve the problem.
Are there other settings to set in "about:config" page? workarounds? add-ons?
Thanks for your help in advance.
PS: sorry for my english, I'm still learning.

I have done some other tests and disabling all settings i mentioned above in the topic the issue is solved.

Safari, Proxy Authentication, and Certificate Authorities ( for https )

A recent update to Safari has caused it to not work with our proxy authentication. It will not provide authentication details when looking up SSL certificate authorities, causing certificate errors on all https:// websites. All other traffic (http, https if certificate is bypassed, plugins, etc.) seem to work just fine. Is anyone else having this problem? If so, is there a fix?
It occurs on Mac and PC. I am using SquidGuard with NTLM authentication. All other browsers on our system (IE x.x, FireFox, Chrome, Opera ) don't have this issue.

I have the same problem and it's frustrating as can be.
What happens to me is that When I bring my laptop to work, and put it on the work network and launch Safari, Safari informs me that each of my plugins is invalid and then uninstalls them - I'm effectively not able to use any plug ins at work, and I have to go hunt them down when I get back home (for reference, The extensions are still physically in \users\me\Library\Safari\Extensions - so when I get home I can just double click on all of them)
I opened a case with apple and I encourage you to do the same. Perhaps if enough users complain they will find a gentler way to work with it.
They had me do a capture and after analyzing it said it was an issue with the work network and not being able to valdate the extensions.
It sounds like the same issue you have - as my work network uses a proxy as well.
The rep suggested that I use a different browser at work, but I'm so used to clicking safari, that I do it out of habit.
I really like Safari, and hope they get it fixed - Safari may not get respect in the windows world, but it's really a great browser - especially on a laptop where screen real estate is limited (where I often hit command-shift-\ to hide the address bar to see more of the page)

HTTP Basic authentication for proxy service and its wsdl?

Hello:
For some reasons I needed to configure the HTTP basic authentication on a proxy service at OSB 11g. Everything was OK until I realized that, additionally to the authentication when calling the service, the OSB also asks for credentials when I try to get that proxy wsdl file.
My requirements are to secure the proxy service when is called only, not when retrieving the wsdl.
Is this possible to configure on OSB / WLS? How?
Greetings!

If I'm not wrong, Basic authentication is Transport level feature. So passing User/Password in SOAPHeader doesn't make sense. SOAP message can only be sent when you have a HTTP Connection open. During opening of HTTP connection User/Password is required for basic authentication.

Hi,
According to the log, it seems that TMG firewall denied the request and replied with an HTTP 407 response, indicating that proxy authentication was required. This was done because the Forefront TMG firewall did not have any access rules which would allow
the anonymous request. Please check if you have configured related access rules.
When did you recieve this log? Is there anyting wrong? Which authentication method you have used, Kerberos, NTLM or other?
It seems that each time a web proxy client requests a resource through a Forefront TMG firewall that requires NTLM authentication the client is actually denied twice during the transaction before being successfully authenticated and allowed access. When
the Forefront TMG firewall is configured to use Kerberos there is only a single denied request and HTTP 407 response and then contact a domain controller and obtain a Kerberos ticket to present to the TMG firewall to gain access to the resource.
If you configured the TMG clients with a certain proxy name, please make sure you typed the TMG's domain computer name only (not IP address nor alias).
Best regards,
Susie

Is IOS FW Proxy Authentication Compatible w/ HTTPS server?

Can proxy authentication be triggered via https as well as http? The document below on auth proxy only mentions http.
But the following document on https shows that https is triggered by adding secure-server parameter to the end of "ip http". "ip http secure-serer". If anyone's tried this out - would be interested to know the result. Thanks.

http://www.cisco.com/en/US/products/sw/iosswrel/ps1833/products_feature_guide09186a00800d9eee.html

I have tried this and it works. If you specify "ip http secure-server" command, the "Username/Password" dialogue between the end client and the authenticating agent will be secured. Otherwise the username/password is sent in clear text.

HTTP/1.1 407 Proxy Authentication Required for cloud connection

I am using Jdeveloper version 11.1.1.7.1 for ADF deployment on cloud service(Java and DB services).As instructed ,I have followed all the steps and in jdeveloper .when I tried to Authenticate the created connection with username and password, i am getting HTTP/1.1 407 Proxy Authentication Required .I am clueless how to solve this,Followed all the blogs but no luck.Please help on this,

Presumably you are behind a FW, does your proxy require authentication if so did you set it with "Tools > Preferences > Web Browser and Proxy > Proxy Server Requires Authentication". Also what is the version of your JCS SDK ? You can check it by:
java -jar javacloud.jar -version
It should be something like 15.1.2.0 or later ..

Is there an issue with the latest version of FF with HTTPS requests and Proxy authentication?

I'm currently working inside a cope network behind a proxy, which requires authentication.
When browsing to websites externally to our network I would usually only be promoted once for authentication details; after that I would never see the prompt again until after restating the browser.
However after the latest update I've found that when visiting HTTPS sites I'm promoted for my login details. But even though I enter the correct information the prompt does not take the details and continually asks until eventually our proxy closes the connection (usually with my account now being locked).
My other browsers (IE, GC) work fine without problems.
Any ideas?

It could be a regression in Firefox 18 that wasn't present in Firefox 17. The developers are known nowadays for including too many experimental changes and my bet is one of them is causing this.
But to confirm, could you downgrade back to Firefox 17 and still see if it works well with proxy authentication?
