Security :: Getting Access Denied When "user Must Change Password At Next Logon" Is Checked?
Mar 1, 2011
I have got a RHEL 5.6 server configured to authenticate via a Windows 2008 domain controller via LDAPS.Everything is working fine, except from the following: When I create a new user in Active directory and check the option "user must change password at next logon", the new user cannot logon and gets an "access denied" message. In /var/log/secure, I find the following:
Mar 1 14:43:21 cpssvn10 sshd[5363]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.3.12 user=testuser2
Mar 1 14:43:21 cpssvn10 sshd[5363]: pam_ldap: error trying to bind as user "CN=CPSS Testuser 2,OU=IBM,DC=cpss,DC=smarterplatform,DC=com" (Invalid credentials)
Mar 1 14:43:23 cpssvn10 sshd[5363]: Failed password for testuser2 from 192.168.3.12 port 4583 ssh2
As soon as I uncheck the "user must change ..." option, the user can log on without problems. Also password change via the passwd command works.

Cannot seem to use my mysql password, keep getting the error
"Access denied for user 'root'@'localhost' (using password: YES)"
So I tried checking my password using mysql -u root -p and I get the same error as above. I've tried accessing mysql with skip grant tables disabling the need for a password so I could reset my root password. After going through the necessary steps I still get the error above when typing my password in for mysql.

I am pulling my hair out once again after trying for over 15 months off and on to get a tv tuner working under linux. I have just received my new tuner card which I thought was supposed to be easy to run, a HVR-950Q, no luck yet. But first I am trying to use something called mysql (new to me), for mythtv and [I] keep getting
# mysqladmin -u root password ma
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)

for some reason root lost grant privileges and I can't get it back. The user got grant_priv = 'Y' in the usertable. I've tried to reset all the priviliges to the user by killing MySQL process and started up again without grant options with no luck. I've also tried lots of other things but can't seem to get it work. Here is what I get: Quote:
[root@xxxxxxxxx mysqldba]# mysql -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 2
Server version: 5.0.77 Source distribution

I need to get an old MySQL Client(4.1)to connect to an even older MySQL Server (3.23).The goal is to do a Java/JDBC connect to the old Linux/MySQL 3.23 database, in order to update text information for a Lucene search (which will also run on linuxdev2). The problem is that I can't connect to the Linux/MySQL 3.23 server from a remote Linux/MySql 4.1 client. I can't connect from JDBC; I can't connect from "mysql":
Code:
LOCAL (intranet):
mysql -uSOMEUSER -pSOMEPASSWORD mysql => OK
REMOTE (from linuxdev2):
mysql -uSOMEUSER -pSOMEPASSWORD -hintranet mysql => FAILS:
ERROR 1045 (00000): Access denied for user: 'SOMEUSER@linuxdev2' (Using password: YES)

I set up a servber on my local machine, & also PHp - Both working fine.I'm trying to load up MYSQL i have installed it, & *can* start/stop the server. however if I do anything else with it, I get this error :-
Quote:
root@gordon-desktop:~# sudo mysqladmin -u root -h localhost password MYPASSWORD
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
Query :-
1) How do I know MYSQL is actually active ? (apart from the message it says that its statrted (or stopped).
2) Is there a way to
a) Find out the usernames that are recorded on the MYSQL server ?
b) set / RESET the 'root' username (I know MYSQL root user is different to PC root user)
c) anything else I can do on the PHP / website code to see if MYSQL is working
(as yet, no tables / databases etc have been set up - as I can't get past this error message - I get the same error when setting up a database.)
Ps I did allow my usermname (when logged in to ubuntu) to edit / create files in the /usr/www/ directory (but it is still OWNED by 'root' - that directory)

I have a Debian etch system I haven't fired up for about a year because the mobo went bad.I had one user setup, I hammered it with all my normal passwords and finally got a prompt that said 'Access Denied'So my understanding is that I figured out my PW, but for some reason this user doesn't have access anymore.Is there a workaround for this? I am just trying to retrieve some files from the drive I don't have a problem formatting it.
Also I tried hooking it up to a windows machine:I loaded Ext2 IFS, it recognizes the drive, but says it can't load it - something to do with the headers being closed out improperly, and basically said I would have to boot it in linux then try it in windows.I tried this after I got to the linux logon prompt (the bootloader had scanned the drive because it hadn't been scanned for x amount of days), this didn't help Ext IFS read the drive.

I have now been trying to find an answer for the following for a while and can't seem to get anything.On previous linux distros we had the option available "passwd -e" which allowed us to force the user to change their passwords upon the next login.s functionality however seems to be excluded from latest linux distros (currently using RHEL 5.4)...Does anybody know how the same effect can be achieved and perhaps any idea on why this option was removed as it was great for securing passwords

Is there anyway to prevent a user from being able to logon at a machine (Terminal and XWindows) but allow that user to logon remotely using SSH? This user is for remote capture of logs only - on a private network (no internet access).

I have a NIS server and a web server as a client. I have a regular linux user (without root privileges) "techsupport1" on NIS server.
On the client web server, I have root user, and my clients. Now what I want to achieve is, allow my user "techsupport1" to access the web server, but instead of logging in using root user, I'd like the client to use username "techsupport1", but in the same time, give that user root privileges on the web server (client). The reason, is that I have more than one user who need to manage the web server (client), so I want to be able to clearly see in the bash_history, who has been running what commands. right now, when I login as a techsupport user to the web server (client) from my NIS server
[code]...
I don't have root privileges, also my gid is matching to gid of a customer who has the same 517 on the web server. How can I configure, so when a tech support agent 1, logs in to web server, NIS grants root privileges, but keeps the techsupport username?

Our system is based on RH4 and is using pam_tally and faillog to record failed attempts and to lock users out after 5 attempts. We have a requirement to provide a normal (non-root) user logging onto our system, with information regarding the number of failed logon attempts made on their account before the current successful logon (similar to the functionality provided by HP Protect Tools on Windows). My first idea was to add 'faillog -u $USER' to the bashrc, however by the time the bashrc is run - the user has been successfully authenticated and the faillog has been reset back to zero.

I am using mint 8 for a 2 weeks, I am noob to linux but I like Mint than any other linux distro which is great alternative to windows. I have a problem regarding password reseting.
1. My laptop automatically get logged in without asking user name and password.
2. I tried to change password for newly created user and root user using graphical way but it does not work.
2. I can perform administrator task using only OEM user which is default inbuilt user of mint.
How can make my laptop to ask password when mint get booted? How to change password for other users?

At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.
