Full Discussion: AIX login problem
Operating Systems AIX AIX login problem Post 302156213 by gus2000 on Monday 7th of January 2008 05:09:35 PM

The following summarizes the AIX login process:

* A user enters an id at the login prompt.
* getty starts the login program to check /etc/passwd and /etc/security/passwd.
* login starts a login shell.

Since the attempt is logged, I'd say it's likely an authentication problem. What is the authenication method for these users? Is it different from the other users? And what is the shell for these users?

If it is an authentication problem, then the failed logins should be listed here:

/usr/sbin/acct/fwtmp < /etc/security/failedlogin

It is possible that the logiles utmp, wtmp and failedlogin could impede the login process if corrupted, but that would tend to be a systemic problem and not just for a subset of users. Still, since the latter two logs grow without limit, this might be a good time to archive and clear them.

kf

KF(1)							    BSD General Commands Manual 						     KF(1)

NAME

     kf -- securely forward tickets

SYNOPSIS

     kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable]
	[-h | --help] [--version] host ...

DESCRIPTION

     The kf program forwards tickets to a remote host through an authenticated and encrypted stream.  Options supported are:

     -p port, --port=port
	     port to connect to

     -l login, --login=login
	     remote login name

     -c ccache, --ccache=ccache
	     remote cred cache

     -F, --forwardable
	     forward forwardable credentials

     -G, --no-forwardable
	     do not forward forwardable credentials

     -h, --help

     --version

     kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS.

     In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e.  kinit --forwardable.

     telnet is able to forward tickets by itself.
