[SOLVED] SSHD login authentication failed with LDAP
location: linuxquestions.com - date: September 2, 2011
I have a openldap server running on one machine (fedora10) and pam_ldap.so and nss_ldap.so running on the other machine.
I have added a new user to the LDAP server database, this user is not created on client machine.
1. Now if i try logging with this new user using SSHD I am getting error messages, the error messages are as follows at client side
2. Why SSH is giving errors for these users??
3. SSH will send "INCORRECT" password to LDAP if i create only user on client machine. how can i authenticate users using LDAP without creating accounts on client machine?

Error 204 Authentication failed with Freenx/Nomachine
location: ubuntuforums.com - date: November 14, 2012
I am getting the typical 204 authentication error when attempting to use Nomachine/Freenx to connect to either local computers here in the office or outbound ones at other sites.
I'm attempting to use SSH authentication through a central server "hadrian".
NX> 203 NXSSH running with pid: 4285
NX> 285 Enabling check on switch command
NX> 285 Enabling skip of SSH config files
NX> 285 Setting the preferred NX options
NX> 200 Connected to address: 192.168.2.68 on port: 6235
NX> 202 Authenticating user: nx
NX> 208 Using auth method: publickey
NX> 204 Authentication failed.
Am I doing something wrong here? My understanding is that Nomachine can do normal SSH authorizations with no password needed by simply reading the /home/USER/.ssh/authorized_keys file.
Is there something else I need to do to make this work?
Login Authentication Failed and Cannot Enter Recovery Mode
location: ubuntuforums.com - date: September 1, 2010
Hello Everyone. Earlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.
I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD? Thank you for the advice.
[SOLVED] Cannot login via ssh with key
location: linuxquestions.com - date: July 31, 2012
I have a server at home for file sharing, in which debian is running. I used NFS for sharing, but i want to switch to sshfs. There is one partition on the server which is nearly public (at local network) so I want to create a keys with no passphrase to log in without typing password, because other family members should be able to log in too. So I created user "sdileno" on the server. I made a pair of public and private key on my laptop pc and loaded public key to the server. But still i am not able to log-in to the server without typing password. There is what I did:
There is what I did on client
[SOLVED] GUI login for root with sddm on openSUSE Leap42.1
location: linuxquestions.com - date: November 22, 2015
Yes, I know. Yesyes. I don't need that to work with it, I need it to change the font settings.
Funny as it sounds, some programs (YAST2, Firefox ...) use root's settings for font size etc. which is a major PITA for displays with the current resolutions and number of pixels per inch.
What I want to do, is just log in to Plasma / KDE, fire up system settings, change all font sizes to 16 pt and log out again. Anyone here who knows how to outsmart sddm (login manager of openSUSE et al.)?

[SOLVED] Ubuntu stuck at black login screen; problem with .X11unix file
location: linuxquestions.com - date: March 1, 2012
I have an Acer Aspire One with the latest version of Ubuntu installed with the GNOME UI. Everything has been running fine on the computer until recently, when I hit a snag that I can't solve by myself.
I'm not sure what might have caused the error, other than a possible update glitch from Update Manager, as that is the last thing I did before I shut down the laptop when it was working last. The updates installed fine, but they might have bored the system somehow.
One day, out of the blue, I turned on my laptop and I was confronted with the black terminal login screen. After entering my credentials, I tried the "startx" command, but I received the following error, "/usr/.X11-unix has 7111 bad permissions," or something like that.
So I searched around online, and there were a few suggestions to use "chmod -7111 /usr/.X11-unix". So I used that, and then ran "startx" and I was able to boot into the GUI without a problem.
How to add new users with LDAP authentication and Apache 2.2 Ubuntu 10.04 lts
location: linuxquestions.com - date: June 1, 2011
I have set up Apache to use LDAP authentication on our Ubuntu production web server. The users are authenticated on another server (AuthLDAPBindDN) which is not controlled by us (we currently don't have root access to it).
Therefore, my question is, How does LDAP handle the authentication of new users? At the moment, new users are unable to login and are presented with a 401 status code, which is fine for now... But would it be possible to divert the new users to a web page where they could fill out their details and be able to login. i.e. If the logon user name is not recognized, divert the user to the create_user script.
Also, would any changes need to be configured on our production server, or the server that LDAP authenticates against?
Any pointers would be great.
[SOLVED] SSH login with no passwords for distributed program on red hat
location: linuxquestions.com - date: August 4, 2009
I'm using a program on a group of servers which contact each other using SSH.
I've got the authentication keys setup with no password and the keys are on each box. But when one box tries to connect to another it wants the password for the user it's trying to communicate with.
So the main problem is there is a lot of communicating within this program so it's important to allow each box communicate with each other without the use of a password.
Does anyone have a solution?
I'm using OpenSSH 4.3 with OpenSSL 0.9.8 on Red Hat Enterprise Linux Server 5.3 (Tikanga).
I'm also using SSH on Ubuntu(Intrepid) to connect to these servers at the mo as i don't have direct access to the boxes.
