Proxy authentication window

I've installed Java Web Start and I'm experiencing the following behaviour.
My web browser has a proxy configured and in the Java Web Start
preferences it's specified to use the browser configuration (not
manual).
Now, sometimes the window asking for proxy authentication appears,
even when I'm not launching a Java Web Start application.
It seems to me that the proxy authentication window appears when a new Java Virtual Machine is invoked.
Is it a known behaviour ? What's the reason for it ? How can we avoid
it ?
We think it would be very annoying for a user beeing asked repeatedly for proxy authentication, expecially when he/she doesn't understand the reason why it happens.
My best regards

... to tweak the config files ?
If you are on Win32 and your proxy is using ? la NTLM authentication then the 1.4.2 should fix this...

ITunes Proxy Authentication & iTunes Store can't connect

1) Stop Proxy Authentication Window
To solve the issue with the Proxy Authentication window coming up over and over please add the following to lines to your Proxy Configuration above the first DENY rule:
acl iTunes browser iTunes
http_access allow iTunes
2) Access Content in iTunes Store with Proxy
If you are having any issue with Content being displayed in the Store with Proxy, please follow the steps below:
In the Internet settings remove the tick next to "Autodetect" and "Proxy Server"
Launch iTunes and Connect to the Store (you should see no result when on Corporate network with Proxy)
in the Internet settings add the tick to "Autodetect" (or) 'Proxy Server" (set as you had before)
Launch iTunes and conenct to the Store, you should see content.
If you did above whilst on Corporate network with Proxy you will see badly rendered Content.
If you did above off Corporate network with no Proxy conencted to the Internet you will see the Store rendered correctly.
If you try this step once off the Corporate Network, the rendered content looks correct even when you connect to iTunes store via Proxy after the fact.

I have the same problem. The only firewall which I use is the wondoes firewall

Safari for Windows won't remember proxy authentication credentials

I'm trying to use Safari 5.1.2 on my work Windows 7 Professional machine to keep my bookmarks and reading list in sync with my iPhone and home Mac via iCloud. On my company network we use a proxy on port 9000 for all browsing, however Safari constantly spawns authenitcation credential prompts when opening pages (or without navigating at all). Selecting the option to remember the credentials does nothing, and the options for usernames and passwords is selected in Safari options but this doesn't help.
It doesn't matter what format I enter my username as. So far I've tried:
user
domain\user
FQDN\user
user@domain
user@FQDN
all to no avail.
Chrome V16 and IE9 have no issues with proxy authentication and they seem to share the global LAN settings. It doesn;t even hinder Safari's ability to resolve pages through the proxy, it's just annoying for each page view to spawn up to a dozen prompts.
Has anyone else had this issue, or shed any light on how to resolve?

Hi,
Just to notify that this exact issue is also on Windows XP. Thanks.

How to set proxy authentication using java properties at run time

Hi All,
How to set proxy authentication using java properties on the command line, or in Netbeans (Project => Properties

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:

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)

Calling external web service - Proxy Authentication error

Using Developer 10.1.3.3 and following OTN example http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html.
I have followed the above example and am trying to test the SendServiceSoapClient.java in JDeveloper. The class compiles ok but when I run it I receive the following error in the log window :
HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 407 Proxy Authentication Required
As I was able to create the proxy with no problems, the proxy settings in Tools->Preferences are valid. I don't understand at what point it is failing as I am able to access the wsdl in the example from JDeveloper. I have checked the system settings for the proxy (username/pwd/host etc) at run time and they are as expected.
Can anyone make any suggestions? I have had my user details checked on our proxy server and it is not blocked from performing any actions. Is the message indicating I am being blocked from accessing the service from the suppliers end?

I have a solution for the problem I encountered.
My collegues who look after the proxy server and network first tried to bypass authentication for the web site www.esendex.com (where the service resides). The same error occurred when trying to call the service.
They then set up a route on the network to send the request straight to www.esendex.com and a rule on the firewall to allow the request 'out'. This has done the trick and the request passes through!
Unfortunately, I am not much clearer as to why our proxy server is configured to block this message type and how come it can't be changed! Hey ho, I have a solution for now!

Proxy authentication doesn't work with JSSE

Hello,
Seems like there is no common way to authenticate with proxy for HTTP and HTTPS.
Connecting to http://... - works fine, but https://... returns error message:
Unable to tunnel through 111.111.111.111:8080. Proxy returns "HTTP/1.0 407 Proxy Authentication Required"
(IP address is intentionally changed in the message above)
I'm using JSSE with VAJ JDK 1.2 and here is a Java code snippet that works well with HTTP connections:
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
System.setProperty("java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol");
System.setProperty("https.proxyHost", proxyHost);
System.setProperty("https.proxyPort", proxyPort);
System.setProperty("http.proxyHost", proxyHost);
System.setProperty("http.proxyPort", proxyPort);
try {
URL url = new URL("https://www.sun.com");
URLConnection connection = url.openConnection();
String authString = proxyUserID + ":" + proxyPasswd;
String encodedAuthString =
"Basic " + new sun.misc.BASE64Encoder().encode(authString.getBytes());
connection.setUseCaches(false);
connection.setRequestProperty("Proxy-authorization", encodedAuthString);
Listening to the network traffic helped me to understand that there is a difference between the way HTTP and HTTPS is handled. For some reason HTTPS ignores all the headers that I specify using setRequestProperty().
Here is example of request and responses sent by HTTPS handler:
Request:
CONNECT 198.175.98.32:443 HTTP/1.0
User-Agent: JSSE
Proxy response:
HTTP/1.0 407 Proxy Authentication Required
Date: Wed, 07 Nov 2001 22:04:11 GMT
Content-Length: 233
Content-Type: text/html
Server: NetCache (NetApp/5.1R2D4)
Proxy-Authenticate: basic realm="NETCACHE2"
Please note that there is no Proxy-authorization header in the request above.
Compare it with HTTPS request sent by Netscape browser:
Request to proxy:
CONNECT www.sun.com:443 HTTP/1.0
Proxy-authorization: Basic am0vbDphrGxHa22lLg==
User-Agent: Mozilla/4.76 [en] (Windows NT 5.0; U)
Response:
HTTP/1.0 200 Connection established
Proxy-Agent: NetCache NetApp/5.1R2D4
So, the question is:
What is the best way to pass "Proxy-authorization" header to proxy server??
Thanks in advance for your time.

Hi Guys,
Just like, i assume, all of you, i've had my battles with javas' handling of https comms from behind a firewall. I'm actually amazed at how something that is a simple combination of protocol and security should become so messy.
Luckily , i managed to get all my requirements met, but the sad thing is after all that hard work, i'm not much closer to understanding why the standard java sdk (im using 1.4) forces us to endure such painful tasks.
Really, Java is quite a mature language now, and one of its touted benefits is its applicability to web and internet technologies... so why the messy proxy code when dealing with ssl?
Anyway, i didn't really come here to b**tch, but rather to point you all to a handy library from apache - httpClient - http://jakarta.apache.org/commons/httpclient.
After implementing ssl proxy tunnelling and all the fun that goes with it, i found this tool, and subsequently deleted all that ugly code, and let http client deal with all that for me.
Its seriously simple, heres a snippet:
httpClient = new HttpClient();
httpClient.setTimeout(responseTimeoutMillies);
Protocol myHttps = new Protocol("https", new SSLContextBasedSocketFactory(sslContext), targetServerPort);
httpClient.getHostConfiguration().setHost(targetServerHost, targetServerPort, myHttps);
if (useProxy)
     httpClient.getHostConfiguration().setProxy(proxyHost, proxyPort);
        httpClient.getState().setProxyCredentials("my-proxy-realm", proxyHost, new UsernamePasswordCredentials(proxyUser, proxyPassword));
}This initialises the client, and after this, making http requests is simple:
String response = null;
PostMethod postMethod = new PostMethod("/secure/blah.jsp"); // A HTTP Post
postMethod.setRequestBody("Hello there"); // this is the data in the http post body
int responseCode = httpClient.executeMethod(postMethod);
if(responseCode == 200)
    response = postMethod.getResponseBody();...
As you can see, its alot less painful. It certainly makes me feel better, knowing i don't have to support/maintain the ugly proxy tunnelling code. Give it a shot on your next project.
Hope it helps.

Marcus Eaton

Exchange server 2013 proxy authentication

Hi All,
I wanted to know what is the recommended proxy authentication for exchange server 2013.
I have observed the following from different proxy authentications:
1. Negotiate: By default, the proxy authentication is set to negotiate and uses anonymous as Log on network security(un-encrypted MAPI)
2. Basic: It always prompts for the user credentials and uses encrypted MAPI.
3. NTLM: Use negotiate at MAPI level by default
Please provide me some information on different authentication mechanisms and the one which is recommended to use.
Thanks,
Srinivas.

Hi Srinivas,
According to my knowledge, there are my views below:
Basic authentication: If you select this authentication type, Outlook will prompt for username and password
while attempting a connection with Exchange.
NTLM authentication: If you select this authentication type, exchange does not prompt users for a user
name and password. The current Windows user information on the client computer is supplied by the browser through a cryptographic exchange involving hashing with the Web server. If the authentication exchange initially fails to identify the user, the browser
will prompt the user for a Windows user account user name and password. So, when Outlook is trying to connect to Exchange and if the machine is domain joined, there isn’t a need to provide password.
Negotiate authentication: Enabled by default in Exchange 2013. This is a combination of Windows integrated
authentication and Kerberos authentication. If we employ negotiate authentication, exchange will authenticate the client using NTLM authentication type and if unable to verify authenticity, will challenge the client to authenticate using a username and password.
And you could set the authentication type like this:
ExternalClientAuthenticationMethod : Basic
InternalClientAuthenticationMethod : Ntlm
IISAuthenticationMethods : {Basic, Ntlm, Negotiate}
The command below for your reference:
Get-OutlookAnywhere | Set-OutlookAnywhere -InternalHostname "internalServer.contoso.com" -InternalClientAuthenticationMethod Ntlm -InternalClientsRequireSsl $true -ExternalHostname "externalServer.company.com" -ExternalClientAuthenticationMethod Basic -ExternalClientsRequireSsl $true -IISAuthenticationMethods Negotiate,NTLM,Basic
If you have any further questions, please let me know.
Best regards,
Eric

Why do I keeping getting proxy authentication request when trying to read Gmail?

I am behind a Blue Coat proxy, whenever I try to hit gmail or google play, I get a pop-up that request user authentication (moz-proxy). I have seen a number of post on this and tried the fixes. Nothing seems to help. When I tried this: https://support.mozilla.org/en-US/questions/943488, Step three: network.automatic-ntlm-auth.allow-proxies – FALSE, I was block from hitting any webpage. I have tried opening is SAFE MODE, that did not work. Are there any other solutions?

"IE’ uses windows authentication, and authenticates with proxy server silently behind the scenes. Chrome uses IE’s settings in windows, for proxy settings. Hence the same behavior as IE. But Firefox, tries to do it on its own, that is why it tries to authenticate and find out if you have access to the site.
But, yeah, for your problem, the best way would be to ignore proxy for the site if you know they are already blocked."

No, but you should get around the problem by using the offline installers.

Can I get the AD Login to fill in the Proxy Authentication?

Hi,
Here at work (an FE college) we have a windows based Proxy system that it's as hard as Fort Knox. Currently, when users have logged in, the Proxy Authentication box pops up, the users fill in their details, then another pops up and they fill it in again (one is for HTTP, the other HTTPS). Thing is, for some people, it continually pops up, causing great annoyance and complaints.
What I would like to find, is a way that when the user logs in (using the AD for authentication), that the details are then placed into the relvant fields in the Proxy Authentication.
I don't work for the IT department, so I'm not in a position to know many answers about the windows based stuff, but will try to follow any advice or questions you have.
Thanks,
LCM Technician

The security code is the Apple ID of the person who setup the account. You will need to have the person you purchased the iPhone from remove their information from the iPhone.

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.
Bye

ITunes proxy authentication BUG

Hello there,
i´m starting the iTunes 10.7 under Windows 7.
iTunes 10.7 gets the proxy settings from the IE9. Now the iTunes wants an proxy authentication o.k. ... but in my case i must repeat the loggin 5 TIMES.
Remember my Passwort ... dont work....
Anyone else have the same Problem?
Does anyone know iTunes 11 fix the proxy authentication BUG ???
How can i solve this problem ?

I have this issue, but at least 10.7 gives you the option to put in your authentication details.
iTunes 11 does not have proxy authentication at this point in time so do not upgrade if you require this.
I have upgraded to version 11 and now can't access the iTunes store.
