linux-howto

http://www.unix.com – For some reason i cannot login using root or other accounts on my Linux system. When logging in at the main console it says "Authentication failed" in a dialog box with an OK button. The Linux system is Redhat 4.7. I've already checked /etc/pam.d/login, /etc/security/access.conf and /etc/securetty files but everything is correct. I have already checked if /etc/nologin file exists. I have accessed the files mentioned above using rescue mode. Can anyone help me for this? (HowTos)

I have created a virtual machine and installed Redhat 6. I am having issues connecting using public key authentication.

I can use PuTTY on my Windows host to connect to the redhat guest, where I am prompted for a password.

I've been having this problem for almost a week. On my HTC EVO 4g, when I log into the Facebook app, I can see my news feed for about 10-30 seconds before I am kicked out with the "Authentication Failed" message.

I screwed up. I had my buddy help me with the installation for f16, and he didn't use my name, he used another name of someone else he was helping out. I looked up how to change your username, it said to edit the /etc/passwd file. I knew this was bad, I always heard, "never do this." Well I did it...

I have a webapplication which uses claims based authentication. The STS is ADFS 2.0. When I am in the intranet and use IE, IWA is used and no login dialog appears. When I am on the internet zone, the Forms based authentication of ADFS is used.

I have two Ubuntu 12.04 systems, one a desktop, and the other running as a NIS/NFS server (a desktop with lightdm disabled).

Hi All:

I have configured PAM authentication on Linux box to restrict particular group only to login.

I have enabled pam and ldap through authconfig and modified access.conf like below,

[root@test root]# tail -1 /etc/security/access.conf - : ALL EXCEPT root test-auth : ALL

Also modified sudoers file, to get su for this group

<code> [root@test ~]# tail -1 /etc/sudoers %test-auth AL
