My company has policy that user accounts expire once a month and they also get locked out if they re-try login more than 3 times (pam_tally). It gets very annoying every time they come and ask to get password changed.How do I let users change their own password? Also let the system email them every day for two weeks before password expiration and until they change their password?

It seems that karmic has changed the behavior of Gnome's cpufreqselector, so that it requires root authority to make changes, and those changes don't persist after a reboot.
Is there a way to make changes persistent? Is there a way to let admin users change the setting without having to enter a password every time?
I installed SLES 10.2 with SAMBA 3.5.5.43 to retire our old Microsoft Windows 2000 Server and save some money. All was fine until last week when our chief asked to me to set password expiration for all clients. This morning, all users cannot logon because, when they logon, windows asks to change password and then it gives error error "Access Denied".

Im trying to config my intranet to be accessible from inside the network (lan) without need of password and ask for a passwd for those who are viewing from Wan ....
Today my intranet can only be accessed from Lan, external access give me an Unauthorized message, I took look around, try #irc and still can get the appropriated help, I hope that someone here could help me on that...
A piece of my config:

I am wondering how websites like banks are able to determine if you have previously used a certain computer to access the website, even if your router's IP address may have changed and your system's cookies have been cleared. I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.

I've been running Ubuntu Maverick as a fresh install since release, and for the last 2 days, I'm having to log in twice! This is only on a locked screen, not on reboot or switch users. After the first login, I see the desktop for a second, then the screen goes blank. I wiggle the mouse and the login screen is there again. The 2nd login goes as normal.
I have gradually been installing things as I need them over the week since install, but I can't pin it down to any of those. It's getting pretty annoying when the screen saver kicks in!
I am using squid + dansguardian for web and content filtering. And it is working fine. I am forcing users to use proxy through browser configuration. Now I am planning to add another layer to controlling access using ncsa_auth program. I know it is not the most secured but I am fine with it. Plain passwords are fine with me.
I will be giving users some default passwords but I want some program for allowing users to change the passwords for the respective users if they want. Is there any perl script or something web based for the purpose that anyone is using or know of?
just now i have installed squid, it works fine with authentication . I created this authentication in a simple text file by using htpasswd . my question is that is there any web based simple page to change passwords of squid users, because each and every time i cant give direct access to server for my squid users .
