CentOS 5 :: Ident Authentication Failed For User "PostgreSQL"
Mar 1, 2011
I've installed PostgreSQL 8.4 via yum and I haven't edited any conf file. Just did the following: CREATE USER nagios WITH PASSWORD 'nagios'; createdb --owner nagios nagdb But then I try to log in like this as postgres user: psql -d nagdb -U nagios And I get the error message -> FAILED: Ident authentication failed for user 'nagios' Why is this happening? My pg_hba.conf is as following (this is the original config):

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

I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.

I was trying to install winbind on a RHEL5 machine and I had to reboot the RHEL machine. When it came back up, I'm not able to log in as root or any other user.When I use root and give a random password, it says invalid username or password but when I use the correct password, I get an Authentication failed pop up box (under GUI). SSh window says invalid password for random passwords and the SSH window disappears when I type in the right password.Can you please let me know if I can somehow get back in by stopping any of the services

I'm wasting hours on this problem: I'm setting up an always-connectable VNC server loaded via xorg.conf.
This is what I did: yum install vnc-server

I have a centos 5 system with openldap configured. I need openldap for simple user authentication. ie.. to be able to use it for authenticating it from remote applications and systems like mail clients...etc.
I was able to succefully install and configure openldap and ran a slaptest to verify the slapd.conf file for errors and found none. so now all i want to do is to add username and passwords to the ldap database.
iam just not sure what all objectClasses i need to use for Attributes uid and userPassword and what exactly should be the ldif file syntax for the above entries. I tried various sources but i do either get errors while adding or after adding do get errors trying to access it.
above all, iam able to access the ldap server from my phpldapadmin only as a anonymous user and not as a root user that i added as a first entry.

I'm taking over support on some linux machines at my work. I came across a CentOS 5.4 system that my users can't log into anymore. When I try to login as root at the console, I get an "Authentication Failed" error message. If I ssh, then the connection terminates. When I type the password incorrectly, I get the usual message about entering the wrong password, so I know my passwords are correct. These are all local accounts, not NIS or anything.
What I've done so far: I booted into rescue mode and changed the root password. No dice. I booted into single user mode and tried updated pam. Again, no dice.

I've been using Ubuntu since 6.04, not a linux guru by any means but can usually get myself out of trouble.
So, the issue... I installed 8.04 on my mother's laptop some time back as she was having trouble keeping Win 2000 running (she has a low spec no-name generic laptop btw). I live in Autsralia and she in England, i thought i could better support her if she was running Ubuntu... All has been well with 8.04 but with the new LTS release (10.04) i thought i'd talk her through the upgrade... Did the online upgrade via Update Manager, all seemed to go OK but when she went to log on after restart she got an error saying 'authentication failed' even though we are 100% sure we have the user name and password correct... Tried to do a ctrl+alt+F1 to by pass the GUI log on but couldn't get the terminal session to open up, just got a black screen - no command prompt.
So... thought OK re-install... downloaded the ISO, burned and sent her a CD in the post... talked her through the re-install, all seemed to go well (again) - BUT, after restart, couldn't log in "authentication failed" again...
So, remember i'm trying to talk a novice through all this... any thoughts!?!
If i can get her to log in i can then support her via some kind of remote sesion or other screen share... and it wont cost me a small fortune in international calls!!! But if i can't get a log in, i'm dead in the water!?

I wanted to install it on a secondary computer in my house for web browsing and little-to-nothing more.
How can I fix or get around the error 'Authentication failed' when attempting to login?
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 am trying to setup Postfix along with dovecot on RHEL4. I have done the necessary settings in dovecot.conf, yet I am not able to log into the POP3 server. The error I can see through WireShark/Ethereal is "Err- Authentication failed" Some of the important settings in /etc/dovecot.conf are
disable_plaintext_auth = no
auth_mechanisms = plain
auth_userdb = passwd
auth_passdb = pam
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.

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:

NX> 203 NXSSH running with pid: 1428
