Linux User authentication by PAM

[Rameshrajan]

Hi experts,

I have a lionux user account which was not able to login even after password resets. It always says "Login Failure". I think it is something to do with PAM authentication. Do some one have an idea how to reset the PAM Access failure counts? Any help is highly appreciated

Ramesh,
you you tried loging in with other users? Just trying to eliminate user-errrrr aspect of it.

Some more details here please.

Log in using what protocol?

Log in using what user?

It quite possibly has something to do with PAM, but as far as I'm aware, it doesn't keep score on how many bad user attempts you've made and lock you out, unless you've already tweaked the configuration.

I hope you mess up with /etc/pam.d/system-auth. Try to run authconfig program to make sure everything related to authentication with PAM works just fine.

Thanks

from the console

tail -f /var/log/messages

Then attempt a login.

This will tell you whether the login attempt even gets to the point where it talks to the server.

You may also want to check the configuration of the firewall:

service ipchains stop
service iptaqbles stop

Try the login again, because the firewall can be messing with you.

The first thing I would do is to go to
/etc/security folder and do less on access.conf + time.conf files

These are mostly used to limit users' login by console/time .
Try to locate the line that starts without preceding #. This means that the line actually does limit someone.....


Best regards...
