how to assign shutdown and reboot privileges to the user.please tell directory hierarchy privileges for /root,/bin./lib,/tmp,/var,/pro etc ...
And also i would like to give space quota to particular user and directory for users.
I am using CentOS 5.5 and I created few users (useradd john etc.) and now I want to assign privileges to this user on some directories and files in those directories. For example I want to give read privileges to directory "/documents" and all of files under that directory.

Not having a record for the following shutdown, last assumes that the system has been up until the current time and similarly for the shutdown.
The output comes in time order, latest first, each line showing the time of the reboot and the uptime from then to shutdown. Using last -x reboot shutdown to show the shutdown time, here's an illustration
Code:
shutdown system down 2.6.29.6-smp Sun Mar 7 15:35 - 03:02 (11:27)
reboot system boot 2.6.29.6-smp Sun Mar 7 09:35 (05:59)
09:35 until 15:35 is 05:59.
When the uptime exceeds 24 hours it is shown as (<days>+<hours:minutes) like this
Code:
shutdown system down 2.6.29.6-smp Sun Feb 21 12:39 - 13:20 (00:40)
reboot system boot 2.6.29.6-smp Sat Feb 20 09:39 (1+02:59)
09:39 until 12:39 the next day is 1 day 02:59.
The time in parentheses at the end of the shutdown lines is normally the time until the next shutdown.
So far so good. The incorrect output is for the last reboot and shutdown of an old wtmp file. Here's the output of last /var/log/wtmp -x reboot shutdown; last -f /var/log/wtmp.1 -x reboot shutdown
Code:
[snip]
reboot system boot 2.6.29.6-smp Fri Mar 12 07:42 (01:54)
shutdown system down 2.6.29.6-smp Fri Mar 12 01:31 - 09:37 (08:05)
wtmp begins Thu Mar 11 08:25:26 2010
[snip]
reboot system boot 2.6.29.6-smp Wed Mar 10 14:12 (15+01:42)
shutdown system down 2.6.29.6-smp Wed Mar 10 12:41 - 15:54 (15+03:13)
[snip]
The boot started at "Wed Mar 10 14:12" which had an actual uptime of 1 day 11:20 is reported as 15 days 03:13 which is the time from then until the last -f /var/log/wtmp.1 -x reboot shutdown command was issued. The time from shutdown to shutdown is similarly affected.
In researching current ldap issue (not being able to do anything but log in) it seems that there are no concepts of privileges, roles, etc. that could be assigned to a user in LDAP.
I've only seen fields that deal with name, organization, etc., not with application-specific access control.
I have to assign certain access privileges to users authenticated via LDAP server based on the privilege level mentoned in the LDAP server. How to attain this.

All of as now the add-to-panel item that via it you can shutdown the PC without the need of typing any password to gain root privileges.

I mean, this app is run without root privileges by me, the simple user, and when clicked the PC shutdowns via a signal from this app to the login screen....

I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

I accidentally promoted my initial account to admin and now I want to revert it but I don't remember the specific initial user privileges.So there are 2 questions:
1) First, is it safe to "downgrade" the account, logging in with another one? In general what's the best way to do it?
2) Could someone enter Administration->Users and Groups->[select initial account]->
Advanced Settings->User Privileges and list the privileges that are on by default?
I repeat I want the privileges of the initial account, which I suspect are above those of basic users (that are added later) and below admin...
