HTTP PROXY: Twice User Authentication Required! Why?

Each time, FF pops 2 boxes to require the authentication.
The first time the pop-up window says: The proxy moz-proxy://xxx.xxx.xxx.xx:**** is requesting a username and password. The site says: "'''moz-proxy://xxx.xxx.xxx.xx:****'''"
If I type the username/password into the 1st windows. It is wrong. And the same windows box pops. I have to click the cancel button. And then...
The second one says:The proxy moz-proxy://xxx.xxx.xxx.xx:**** is requesting a username and password. The site says: "'''proxy'''"
I fill the username and password into it, it works well.
Does anyone know the reason why it work in this way!
Could you please tell me how to disable the 1st windows box!
Thanks so much!

Same here.
Firefox ver 10.0.2
Win XP Prof 2002 SP3
The 'use no proxy solution' is not an option here (at work) because without the proxy settings I cannot get on the internet.
Searching for this 'nag' I found that it first appeared when FF ver 4.x was introduced. After several updates it disappeared for a while until now..... Which bug has been reintroduced???

HttpUnauthorizedException: Proxy or Server Authentication Required

Hi,
the exception we had from weblogic_10.3.5 to successfully pass internet proxy authentication seems not working.
here you go,

and still the same exception occurs, any ideas ?

i m not using any specific proxy server it's our official internal proxy.

BBID User authentication required

I received an email to validate my blackberry ID credential....I clicked on the link. It then asled me for my email and password. Do not remember my password or even the recovery question answer....so cannot use BBM or any of the apps. Just going around in circles as cannot get round the recovery question. If do not know on next attempt will be locked out!!!!
Anyone have any suggestions on how to get around this please?

Hi and Welcome to the Community!
Please see this "sticky" post for helpful information concerning your BBID situation:
http://supportforums.blackberry.com/t5/BlackBerry-World/How-to-regain-access-to-your-BBID/td-p/25467...
Hopefully, this information will be of use to you. Given your situation, I suspect you cannot get past this without human intervention (which is discussed in that post)...all of the automated recovery methods require either the correct security question response or that the BBID already have been validated, which is the step you are actually now on. Hence, I doubt that the automated recovery methods will work for you.

Configuring the application server to use HTTP proxy server

Hi,
I am trying to configure LiveCycle ES2 to access services over the internet and since my Livecycle server connects to internet through a Proxy server, I have referred to section 5.8.2 of LiveCycle install_weblogic.pdf that states the following:
If the computer that LiveCycle ES2 is running on uses proxy settings to access external web sites, the
application server should be started with the following values set as Java virtual machine (JVM)
arguments:
-Dhttp.proxyHost= [server host]
-Dhttp.proxyPort= [server port]
However, I am getting the below exception while running the LC application as my Proxy server requires User credentials to connect to the internet:
weblogic.net.http.HttpUnauthorizedException: Proxy or Server Authentication Required.
I tried providing the below JVM startup argument too, but no luck:
-Dhttp.proxyUser= [proxy user]
-DhttpPassword= [Proxy password]
Can you please suggest how to configure User credentials for the Proxy server in Livecycle.
Thanks in advance.

Hi WASIL,
Thank you for your response.
I have followed the above document suggested by yourself and the relevant steps while setting up the Server and the Workbench, and verified the settings too.
The installation guide does highlight the steps to configure a Proxy server. However, the guide does not mention anything about how to handle Proxy server authentication.
Please note that there are Proxy authenication options available in Workbench to configure how the Workbench connects to the LiveCycle server, whereas the problem I am facing here is how to connect the LiveCycle server with internet services through a Proxy server.
I hope that clears the problem statement.
Thankyou for your assistance.

Proxy.pac and authentication

Hello everybody.
I got a couple of iMacs (from OS X 10.6 up to 10.8) running in an environment in which there is Windows AD and the Windows clients use an http proxy with NTLM authentication. The config is pulled from the clients by using the DHCP option 252, which contains the URL to the proxy.pac in this form: http://192.168.50.2:8080/proxy.pac
Now my questions...
How do I set things up on the iMacs, so that they pull the proxy.pac and so that it works with Safari, Chrome and Firefox as well?
As there is authentication (NTLM-based) involved: the iMacs are not joined to the AD, but the only user working on each iMac logs in with the same credentials as in the AD (same user/pass).
Any help will be very much appreciated.
Thanks and regards,
Flavio.

WPAD has been reported not to work with AD servers. I suggest you enter the PAC URL in the network settings under Automatic Proxy Configuration.
Push Forward Proxy info within DHCP

XML Strings as method parameters with HTTP + proxy.

Hi,
We are stuck with the following problem...
We have a client making a remote method call to an SessionBean, and one parameter of this method is a String, which has some well formed XML structure in it.
When we call this method with RMI-IIOP over TCP, there is no problem. However, when we call the same method from long distance (like another building) using RMI-IIOP over HTTP (we have used HTTP Tunnelling facility of IBM WebSphere), some strange things happen.
When we print the incoming XML String in the first case, all is well. However, in the second case the incoming string is just full RUBBISH characters (some binary stuff I guess).
Configuration is such,
App Server = IBM WebSphere 4.02
App Server OS = Linux, Red Hat
Client = Standalone Java Application
HTTP Proxy = Squid
If anyone knows why such a thing can happen, please help. Even a trail would be helpful.
Thanks in advance...

make sure you got the same encoding on both ends....

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

Not Authorized HTTP Error 401. The requested resource requires user authentication.

Hi All,
I have MDS web application on one server and MDS DB on another, both in same domain .
MDS web application is created as new website on same IIS with SharePoint and have their own port assign
In IIS Windows Authentication is added and enabled.
Users do have function permission and module enabled.
MDS is accessible only on server where web application is.
When it is accessed from any computer within domain error is
Not Authorized
HTTP Error 401. The requested resource requires user authentication.
Can anyone offer any suggestions?
Thanks
Zorko

Hi Zorko,
The issue may happen in case:
1. The Master Data Service(MDS) web application is running under a domain user account
2. You didn't register a Service Principal Name(SPN) for the account
3. You are using fully qualified domain name(FQDN) or host name to access the MDS
4. You are able to access the MDS by IP address(http://<ip address>)
If I am right, it is because of the browser choose to use Kerberos authentication to connect to the MDS.
So then, to fix the issue, please:
Register SPN for the application pool account. Enable the delegation.
Or, please force the web site to use NTLM authentication only.
For more information, please see:
How to use SPNs when you configure Web applications that are hosted on Internet Information Services:

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 ..

Proxy User Authentication with SQL Developer

Hello,
I realized that there are 2 methods for configuring SQL Developer to user Proxy User Authentication.
1) one-session method with Syntax:
personaluser[appuser]
2) two session-method with dialog "Proxy Connection"
For me it is unclear, why anybody would want to use the two-session-method.
a. you need username/password for both user acocunts (personaluser and appuser)
b. it is unclear which operations in SQL Developer are using the personaluser account. It seems that the SQL Window is only using appuser account.
What was the motivation to implement Two Session Method?
Best regards,
Martin

I found the possibility that proxy authentication of both accounts can be enforced:
SQL> alter user appuser grant connect through personaluser AUTHENTICATION REQUIRED;
I guess that this is the motivation for implementing the 2-session proxy connection method in SQL Developer.

Martin

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

Invalid Response Code: (407) Proxy Authentication Required

Hi all,
I have created a EJB that will access an external webservice to receive data and will display it in a jsp. But when i call it, i get the folllowing error-
com.sap.engine.services.webservices.jaxrpc.exceptions.InvalidResponseCodeExcpetion: Invalid Response Code: (407) Proxy
Authentication Required (The ISA Server requires authorization to fulfill the request. Access to the Web Proxy is denied)
I have already set the proxy user name and password in visual admin under destinations and also under Web Services Container->Runtime->Settings. Still i get this error. I checked a couple of threads here, that answer to my problem, but none helped! Am i missing something?
Thanks in advance,
Swarna

Hi Swarna
What is the patch level that you are running on?
May be the "auth-scheme" element required by the HTTP specification is missing in the "Proxy-Authorization" HTTP header.
I think that the solution is there in the new support packages or the patch update.
Please check out the latest support packages and apply them.
This should solve your problem.

Proxy Auth authentication required and kerberos

Hi All
Oracle supports the proxy auth trusted subsystem which allows greater scalability through the use of a system wide connection pool. There is a configuration option to "authentication required" to the proxy auth system.
Oracle also support kerberos authentication for external users.
What I would like to know is whether the proxy_auth authentication required is compatable with kerberos authentication. That is can I configure proxy auth to authenticate the tunneled user using kerberos.
Thanks
Edited by: user8002300 on 28/10/2009 16:47

Hi,
What you can do is to set up a reverse and the forward proxy. When the client hits the first proxy it should be configured as a reverse proxy which will redirect the request to the second proxy (this will be a reverse proxy) which will connect to the internet.
Hope this helps.

Dakshin.

Fiori Wave 2 Launchpad HTTP 511 Network Authentication Required

Dear expert,
When I try to call the Fiori launchpad, it returns the code of HTTP 511 Network Authentication Required. BEFORE the login screen shows.
Also error: GET /sap/bc/ui5_ui5/ui2/ushell/shells/abap 401 Unthorized.
However if I maintain the ushell service in SICF on LOGON DATA tab with a specific user A103296.
The homepage(with error "unable to load groups") comes out directly without the login screen.
For "unable to load groups", it says 401 Unauthorized for PAGE_BUILDER_PERS.
However I have both the authorization SAP_UI2_ADMIN_700 and SAP_UI2_USER_700 for A103296.
I suppose there's no need to maintain the logon data for SICF service,right?
On the other hand, Launchpad Admin screen runs smoothly without any issue.
Could you please help on this? Masayuki Sekihara
Thank you very much indeed!
Thanks,
Chloe

Hi Masa,
The issue is solved.
Because the customer's /bc/ui5_ui5/ui2 service logon ABAP class was changed from /UI2/CL_SRA_LOGIN to /IWFND/CL_COC_SYSTEM_LOGIN.
Change the class back to /UI2/CL_SRA_LOGIN and is able to log on to the launchpad now.
But cannot figure why this error message shows about "authentication".
Thanks,
Chloe
