If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?

I need to make a choice on what authentication protocol I want to use for Authentication and Authorization. I was looking at Radius and then literature suggested that Diameter was a better protocol. Keep in mind I need this on a hetrogeneous setup ( linux & windows together). Diameter seemed like a good fit until I discovered that the open source code no longer seems to be maintained ( C/C++).
I was also looking at Kerberos as an option though there is alot overhead with the server. SSL/TLS or EAP? I am looking for simple but secure and am new at the security protocols.
I'm having trouble with my pam_mysql authentication.'ve double checked my md5 password but its correct.What should I be looking at? My /etc/pam.d/system-auth is completely identical to my other server (that works), but this one is somehow reporting that my password is wrong.I've bolded out the questionable output.Here's my error log while trying to connect:

I just installed openSUSE. The installation seemed to go well. After installation, everything loaded up and I was using the OS with no problems.
I restarted the computer to change my boot sequence in the BIOS. Then I got to the openSUSE login screen. I was presented with three options:
1. my username - When I enter in the password I specified during the OS installation it says "Authentication failure"
2. Automatic Login - just says "Permission denied"
3. Other... - Nothing seems to work here
How can I login?

I have been used NX client on windows 7 connected to ubuntu with NX client/node/server with no issues. The matter started when I have formatted Ubuntu and reinstalled NX, from that NX connects but shows a key error as follows:

I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work

The error I can see through WireShark/Ethereal is "Err- Authentication failed" Some of the important settings in /etc/dovecot.conf are

auth_user = root
The users/passwords are setup on Linux file system without MQSql or any other database. SASL etc is not configured at all.

Above mentioned is my configuration. when i try to connect client with SSH it is not sending a request for authenticating user to RADIUS server. what else configuration i have to do, or if there are any mistakes in my configuration
If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no
AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:

I apologize first because I do not know if this is the right section for my problem, but I could not find anything more suitable. I have an Asus 900 with Ubuntu Netbook Remix 10:04 In a nutshell: I realized today, trying to install a new program with Ubuntu Software Center, that I can not anymore authenticate myself as root. Of course I have not changed the password, but the old one is not anymore accepted ("Authentication failed").
The interesting thing is that I can install programs without problems (using the same old password) with the package manager in Administrative Tools (synaptic). Here, the authentication works well. Opening a terminal, I can use sudo to run any command by providing my password, with no problem at all. Following some guides found on the web, I reset the root password (supplying the same one as before) and everything went well. Only .... nothing has changed! Ubuntu center software authentication always fails.
What could have happened? Maybe I did some mistake by editing /etc/sudoers to solve another problem some days ago. Ubuntu told me that my username was not in the sudoers file, so I resolved it by adding to /etc/sudoers the line myusername ALL = (ALL) ALL
I checked the contents of the file and, apart from this line added, it is as it was before (I compared with that on another PC with Ubuntu). Can anyone make some sense out of it? Starting from the fact that the package manager does function ... but software center does not.
I spend all day, trying to make bluetooth working with my phone Nokia 2600. First, i try'it with bluez-utils 3.7, and later with 3.9, but i no luck. So, what i have.

I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
the laptop of my friend runs ubuntu through wubi. The system suddenly freezed and she restarted it manually. After doing a check disk and automatically repaired some packages(unfortunately she doesn't remember what exactly, only just inode information appeared), she can't log in as when she types her username and password the answer is authentication failed. We tried to change the password through recovery mode but nothing happened.
1. Do you have something to propose to solve the login problem?
2. If not how can i access and back up her ubuntu documents through windows?
