Password authentication is happening for all the users for login.

Hi,
I have a Linux System with following version/release

"Red Hat Enterprise Linux AS release 3 (Taroon Update 1) Kernel 2.4.21-9.EL on an i686"

Peculiar problem I am facing on this system.
Any body can login to this system by just entering there login id. That is without entering blank/wrong password.

I tried by configuring Athentication Configuration by enabling and disabling of Shadow Password and MD5. But still the same problem.

I am not able to overcome this problem. Any body have any fix on this.

the problem is in /etc/pam.d/login file


I'm attaching you an example of original file .Change it -and it should fix it.

Thanks a lot Mr.Alex. I am able to enable password authentication by modifying the /etc/pam.d/login file, replacing the optional authentication into required.

Cheers,
Rajesh
