Debian :: Admin Can't Unlock User Account
Feb 7, 2016
I made the mistake of using the command 'adduser' on an already existing user. I was incrementing a name and mis-typed. Now the account refuses to recognize the users password. The user can get in.
I tried resetting the password as administrator (passwd 'user'), but when the user tries, the new password isn't recognized.
I tried expiring the account password (passwd -e user). The user gets prompted for a new password, but the new password still doesn't get recognized.

I ran a test where I login a test user several times using the wrong password to see that he gets locked out after several attempts. Now that I got the test user locked out, how do I unlock the test user? I tried passwd -u <test user>, but it says passwd: Error (password not set?).

I just tried to change a user account by changing its name, password, and home directory. But first I had created a new account with the new name, pass, home directory. I tried to log into the new account but got a dead account. Nothing came up, and it didn't allow anything, complaining about "can't create Nautilus," and other such error messages.
Tried to go into the Constantine login screen and put in "root" and the original password. "Invalid Use..." Tried "root" with the new pass. "Invalid..." So what can I do at this point to get in and create a nice, clean, new account (with admin privs) for the new user?!

I had two accounts. One was an admin and I set the other as an admin as well, but left it without a password since I wanted the new user to enter it themselves. I went into the new admin account and deleted the old, passworded one.
However, this new account doesn't have a password that I explicitly defined on it. How do I change that? The account is the only one and still 'disabled'.

I recently ran into a situation where the ftp user account suddenly could not login. I used the User and Groups system tool to check the user account and reset the password. I then attempted to use ftp and login with the new password and still could not. I then went to check the permissions on the folder and found that the system partition was full, so using gpartd I was able to resize the system partition.
However this still did not fix the ftp login problem. When I opened the User and Groups tool again, all users,including my main account, except root are no longer displayed and all groups are not showing. If I try to add the original ftpuser account I get the message that the user already exists. And my main account works for login still. If I add a new user, it is not displayed in the list either.
If I do a cat /etc/passwd I see all the users listed including the new one I created and cat /etc/group displays all the groups and everything looks like the users are still associated with the correct groups. I can use passwd to change the account password without error and I can use adduser to add another user. Howerver no users are listed in the User and Groups tool and users still can not login to ftp. I can reinstall proftp if needed but I would like to be able to use the User and Groups tool to administer users again.
PS: Forgot that just before encountering the ftp login problem, Update Manager and some updates listed that I attempted to install but got an error and didn't have time to check why. Now I know that the partition was full.

I just installed ProFTPD. So I want to create a user namely ftpadmin. He belongs to the new usergroup ftpuser that I just created.
sudo groupadd ftpuser
sudo useradd -s /bin/false -g ftpuser -d /var/www ftpadmin
sudo passwd ftpadmin
.....
chmod -R g+w /var/www
and when I followed the tutorial
chown -R ftpadmin /var/www/*, chgrp -R users /var/www/*
it returned an error "invalid mode: ftpadmin " why?I want my users to login my server via FTP

I'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.
I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.
Code: Select allgroups fred
fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth
I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.

Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory

How can I implement this: I encrypt a partition using LUKS, and store personal data on this partition. Then create a user account that solely deals with this partition and insulated from the Internet. Normally for each boot I do not even need to mount the LUKS encrypted partition, and when I mount that partition under that special user account, I can make sure that the Internet is cut off.
I'm going to do the installation these days, could you provide a brief sketch regarding what steps I should go through to implement the above result?

I am using Ubuntu 10.04. I installed it a few days ago.
When I open Synaptic Package Manager, it asks for admin password. But, after I give the password, the window vanishes. Thus, I am not able to open Synaptic Package Manager in non-admin account.

I have a problem with the Google search box top right corner in Konqueror, when entering search I recieve an error page "Unsupported Protocol" Google asks for ioslave or kioslave. Also when highlighting text on a page and right clicking with the mouse no search option is given. I created a new user and all works as it should for the new user. What is wrong with my user account? I have reset default values in Konqueror setup.

Deviating from Ubuntu standard, for compatibility with another system in our network (an intradisk NAS with restricted admin features) I have to stick with user IDs below 1000 (namely 501, 502, ...)
In the Ubuntu logon screen, the related users are not shown - and thus cannot be selected for unlocking a session that was locked due to inactivity.

Apache is run as www as is all the files/folders. People are uploading via FTP, scp, so the problem is if I chmod so everyone can read, then rsync as a user it works until new files are added which then my ; if rsync fails with a permission denied. Now I can add a chmod in the script so everyone can read, but since www can already read, I figured I would just change my script to use www. I added the ssh key to his authorized_keys file, but when I try to just ssh in I see this in the secure file;
server sshd[29539]: User www not allowed because account is locked
sshd[29539]: Failed none for invalid user www from ip port 54983 ssh2
Now I read a few places already saying I need to add a password to the account, etc. but before I jump and try all I read, 1st major one, will this now break apache? Will this affect any startup things, etc. and .... will that unlock that user for ssh in or is there another preferred method?

I have a user account which is required to run as part of the operating system and as a service. I am currently attempting to install my companies software on an Ubuntu desktop via wine just for the purpose of finding out if it's do-able.
Is there a way, in Ubuntu, for a user account to be given the local rights assignment to act as part of the operating system and to function as a service in the background?

I'm installing a new laptop for a friend of mine and he wants 3 user accounts, similair to how he runs his windows setup.
1, an admin account, we have called this account peacemaker.
2. his account
3. an account for his girlfriend.
The problem we have is that if we want to do anything from the terminal that requires elevated priviledges, sudo does not accept his password or that of peacemakers. we have done sudo -i -u peacemaker but it still doesn't accept either password, stating his account is not in the sudoers list.
I'm not a massive expert here, but research brought me to this page:[URL]... But that then just means his account has admin rights, which is what we were trying to avoid. We wanted a setup similair to windows where if you want to run someting with elevated privledges if pops up asking for the admin password. This works in the gui, but not in the terminal.
So in short, my question is, is there anyway of having the terminal accept peacemakers user rights from the his normal user account? If I add the account to the sudoers list like it suggests, does this again just give his account the prilvedges rather than saying supply me with the password for peacemaker.
this is probably not really needed and he can just have his account as the main user, but coming from a windows background, he would prefer the 3 user accounts model (2 normal users, 1 admin)

After finally getting Ubuntu 10.10 PPC up and working on my Mac Cube with low capability graphics, I noticed that when I try to run the "User and Groups" from the Administration menu, the program looks like it is starting but then never actually displays.. It shows up at the bottom of the running programs bar and then disappears. Well after having to completely re-install Ubuntu PPC 10.10 and installing all of the updates, User and group Administration still isn't working.. another app that would let me add my wife to my G4 Cube so she could use it?

A regular (non admin) user can create a Truecrypt 7.0a file, but it can't be mounted. The admin password is refused. If you try the regular user password, the error is that you are not on the sudo list.
