JAAS Module for Internet solution

Hi,
We have Portal internet enabled and Other webapplication internet enabled both reside in different networks.
Users get into Web Application with their logon credentials. We want to have a link in this webapplication to the portal and it should automatically log user into portal without asking for username and password.
Is this possible with JAAS module??
If so can anyone please let me know how?? I am new to JAAS.

Hi Abdul,
Thanks for reply. Now I have more information on this Web Application. It is something running on Web Sphere.
Is there any out of the box JAAS module that can be used in this situation?? I came across a scenario where the steps are described below.
1. User logs into Application running on Web Sphere.
2. LTPA(I assume this is like a SSO Cookie as in SAP Portal)will be issued by Web Sphere and stored on Clients Browser.
3. In further clicks on EP links on Web Sphere applications, LTPA will be sent to Custom Login module in WAS.
4. Custom Login module makes sure that there this LTPA token is genuine by talking to Web Sphere.
5. Web Sphere responds saying this is user id and this is genuine.
6. Custom Login module(JAAS) logs user into portal.
So my question here is this Custom Login(JAAS) module available?
Is this process correct ? What exactly needs to be done in this case?
Please advise me .

Solution center suddenly ask for enabling Adobe Flash player for internet explorer for scanning

Solution center suddenly ask for enabling Adobe Flash player for internet explorer for scanning. However, flash player is installed and enabled, but HP Solution center keeps asking for enabling and doesn't let me scan.
Any suggestion?

Hello there! Welcome to the forums @yuvalyanai
I read about the issue you are having with scanning, as you are seeing a message to enable Adobe Flash player.
To begin, I would like to know some more information:
Which operating system you are running and which printer you are working with?
How Do I Find My Model Number?
Which Windows Operating System am I running?
Can you make copies successfully?
Can you print from your computer?
Have you tried updated Adobe Flash player?
Can you scan successfully from Microsoft Paint?
How is your printer connected to your PC, wireless, ethernet or USB?
In the meantime, try resetting the printer:
Press the Power button to turn on the product.
With the product turned on, disconnect the power cord from the rear of the product.
Unplug the power cord from the wall outlet.
Wait at least 15 seconds.
Plug the power cord back into the wall outlet.
Reconnect the power cord to the rear of the product.
If the product does not turn on by itself, press the Power button to turn it on.
I hope to hear from you, have a wonderful weekend

Internet Solution for college students?

Hello everyone,
I am a college student at Navarro and I am looking for an internet solution that caters to pretty specific needs. I will give some general ideas of what I think the ideal plan would be, and anyone who knows a plan that contains some of or all of those aspects please let me know!
:.>No contract - (most likely prepay). This is important because I would only be using it during resident times.
:.>Cost effective - Would like to see a plan from $15-30. The lower the better, I usually have about $200 left over after a semester.
:.>Tolerable speeds - I do not need 15mb speeds, but I average 28kb/s on the college wireless internet. This is not fast enough to have a reliable connection or to stream video for online classes. (720 students to 1 15 mb dsl connection).
:.>Router options - I would most likely want to purchase the router straight up if it is pre-pay / no contract, so if I change dorms etc. there is no hassle. Wireless might be nice, might not be.
I move a lot of data over a connection, so using a phone as a modem won't work. The buildings here are pretty dense, so satelite / wireless signals are weak and unstable at best. It is in a college dorm, so no new wires would be able to be run to the room; existing connections are phone and cable.
Thank you for reading my post! I am looking forward to ideas and suggestions to help improve my situation! It can be very frustrating taking 5 minutes to get into college email, or several hours for larger windows updates and whatnot!

Hi Mcnpenfold,
Is Verizon in your area? If so private message me so that I can get more details. I would like to see what plans are available in your area. If you live on campus does the school allow students to get their own Internet services? Thank you for your interest in Verizon services.

IE-11 internet options page corruption from a installed program,for a solution.

In the past, Microsoft has detected with my PC with a message knowing my internet 11 is corrupted, and corrected the problem with some success. I didn't uninstall the suspect program in time to keep Internet 11 "uncorrupted". I am now personally
looking for the solution, to get Internet 11 options page & delete page to function properly again, ahead of MICROSOFTS detection for the solution used in the past.
Sincerely: Lee Vernon Payne-June 27, 2014-11:34am PST.

Hello Lee, unless this issue is specifically related to Microsoft HealthVault, then I think you'll be better served contacting the general Microsoft support team
http://bit.ly/1qjQUgu or more specifically the IE support team http://bit.ly/1llkKcJ.
If however your concerns are specifically HealthVault related, the details of what HealthVault related program you installed and what the resultant problems are/were would be very helpful in getting us started.
We hope this gets you pointed in the right direction Lee.

Its a late response... but if someone gets the same issue here is the solution.
When you register try uppercase password . That should take care of that issue.
The problem is with function module CRM_ISA_IUSER_SWITCH , Note 946536.
Although the note says 5.0 the problem exists with ISA 4.0 too

Trouble building kernel module for sensor support

Hi, I'm new here but have been using Arch for a while. Recently, I decided to install Arch on an old laptop (Toshiba A70) and have managed to work out most of the kinks to where it runs nicely. Unfortunately, ACPI support is spotty and the /sys/class/thermal directory gives me only cooling_device0. I installed the lm-sensors package and ran sensors-detect, which yielded no results. Although the laptop runs smoothly otherwise, I would like to know the CPU's temp so that I would be able to set up a fan control scheme and CPU scaling (so far it's stuck at the lowest frequency, and that's kind of a big deal for me since the laptop runs on an archaic mobile P4 chip).
Sorry for the story but I felt some context was necessary. I did manage to find a kernel module that would connect those sensors to ACPI for me (http://sourceforge.net/projects/omnibook/), however I'm having trouble building it on the latest kernel. Here is the output from running make:

With 3.6.12, Help menu item "For Internet Explorer Users" results in a "Page Not Found" error. Is this a known bug? Is it being addressed?

Clicking the 3.6.12 Help menu item "For Internet Explorers" item results in a "Page Not Found" error.
The URL of the resultant page is https://support.mozilla.com/en-US/kb/Windows%20start%20page?as=u
Is this a known bug, if so, is it being addressed? If so, someone needs to work faster.
If it is not a known bug, someone needs to get right on it - you want people to switch to Firefox and then there is this bug -- not a good way to impress Internet Explorer users.

Want Wired for Internet, Wireless for file transfers on home network

I live in Dubai where internet in my house is connected straight from an ethernet port in the wall in numerous rooms. I have one wired connection hardwired from port to airport extreme which creates a wireless network for my laptops for internet.. apple tv et al. (home network 10.0.1.1 etc)
In the other room i have a mac mini which is directly hardwired to a second ethernet port. I use this machine for hard wired internet as its essentially downloading continuously for work.
Looking at network setting states..
Wired connection states in network details : (To be used purely for hardwired internet)
router address of (91.74.X.1)
and ethernet port ip (91.74.x.21)
Wireless connection states in network details : (To be used purely for connection to home wireless network and streaming of files within internal networks)
Router (10.0.0.1)
IP4V address is (10.0.1.4)
Subset mask is 255.255.255.0
I would like to force the mac mini to only use the wired ethernet connection for surfing/downloading, and also have an IP from the home network (10.0.1.2 etc) purely for file sharing/streaming with other computers on my home network.
Is this possible ?

NAS is the right tool for this job.
It is expensive but the market leaders.. synology and QNAP have really been doing it for long time and the ability to do file store/sharing and most importantly backup in these is excellent. Pick the best you can afford.. and buy disks that are in the recommended list. ie the cheapest are not always the best.. indeed they seldom are.
Plan very carefully for rotation of USB drives (easy and cheap now with 4TB single drives). Rotate backups with offsite location on weekly basis.
I would buy a 4 disk case.. you can use 4x3TB which are the best value at the moment.. that gives you 9TB of storage.. plus redundancy for a dead drive.
Alternatives are using a Mac Mini as a server.. with a large stack of disks on it.. generally should be thinking thunderbolt if you want speed. Hideously expensive though for now.
You can buy an Extreme or TC.. either would work well. TC allows you easy TM backups without using your NAS..
Edit very large files on the computer. ie copy to computer.. edit.. copy back to the NAS.
Editing very large files over wireless.. not good. Multiply that by mutliple computers.. not even fair.
Copy a large project to the computer.. work on it.. copy back to the NAS.. in the meantime Time Machine should be able to take care of incremental backups.
There are heaps and heaps of solutions.. as long as it is logical and easy to you.. and covers what you need.
Don't skimp.. spending a $1000 for a NAS with disks.. plus extra for the backup disks.. that represents how many day's work for you plus anyone you have helping.. $$$$ ????
A mini as a server is a good alternative.. You don't need to run server OS.. but share files to the network. Very hard to build the capacity of the NAS though.
And a Mac Pro is now a joke without internal slots and cages for drives. (nice machine but wrong for this).
And Apple have nothing in between.. a short tower case.. been missing for a long long time.

Custom JAAS Module - How to use in certification test?

Hello,
I just read the document about certification for custom JAAS modules ("BC-AUTH-SAML Test Plan"). What I don't understand is how our custom login module can get the custom information it needs (like a certain request parameter).
First, what we would like to do is to create a JAAS module which examines proprietary login tickets created by our reverse proxy / authentication server. The example code shows how to retrieve HTTP parameter and headers using the callback methods, so that part is all fine and clear to me.
But for the certification test, the description says that in order to execute the test, the browser must be opened with a certain URL (Test 1, GET w/o password change). That action alone must lead to a valid authentication. However, in your real-world setup, the reverse proxy - sitting between the browser client and the SAP system - would insert a custom HTTP header with the login ticket. Obviously, in the test setup as dictated by the certification document, we don't have our reverse proxy, so my question basically is:
How can I add custom HTTP headers or parameters while running the certification test?

I'd gladly send you something by mail. Two other details first:
- My name is actually not Remo, but Marcel Schoen. I'm just using a company account for this forum. My address is marcel.schoen<at>united-security-providers.ch
- I'm swiss. Do you speak german? Your name sounds german. Falls ja koennen wir das auch auf Deutsch weiter besprechen.
In short, our product is a Web Application Firewall; a reverse proxy for protecting and integrating web applications. Some of the functionality also allows to implement single-sign-on over existing legacy applications with different user bases. And now we're looking into ways to integrate SAP application servers as well (right now, the JAAS module and SAML are the two most likely approaches).

Function Modules for SAP FSCD

Hi All,
Can anyone provide me with the standard Function Modules for FPE1 and FP08 Transaction code respectively. Actually I need to create a payment request based on the user requirement and cancel/delete the same payment request if he/she wants to cancel it. To do this FPE1 and FP08 are used, but I need their functionality in the code, so I need some Function Modules, which can take care of this.
Also you can suggest some alternative ways of achieving my objective.
Any suggestion shall be appreciated.

I have been trying to set up a sequence that uses the same code module for all of the steps in the sequence, but am having trouble referring back to it when I need to send it commands. I have gotten as far as calling the VI in a new thread so that it can be run asynchronously. I can run the simple sequence and it will indeed open the VI, and move on to the next step. When I close the VI manually from the front panel, the sequence in TestStand completes, as expected. So it appears that I have that much working.
My question is how to call the separate thread from the main sequence or other sub sequences when I need to edit the parameters. If I insert an Action step, I am required to select a VI file, but from what I can tell, it opens a different instance of the file, and does not provide an interface with the other instance running asycronously. My next guess was to use a Statement step, but I was not able to figure out how to configure the lookup string to call the VI parameters. Beyond that, I'm not sure how to proceed. Please advise.
My intention is to start the code module VI (asynchronously), run several different subsequences within the main sequence that call that same VI and edit it's parameters, close everything and report on the results. If I am misunderstanding how TestStand is supposed to work, please let me know.
Thanks,

What I do is use a Queue to send data to the asynchronous VI. So it can run and do whatever, but also recieve the commands from the queue. I use an Action Engine that holds the queue reference and sends the commands. So you really just have to call the Action Engine from your sequences.
