User cant log in (close terminal)

Hello everyone

I have a user on my server, Aix 5.3 TL9 sp4. Weeks ago I dont have a problem but today the user cannot log in. let me explain.

Me with root user I can change his password. then I log in with the user and I can change the password and the terminal close. Im using ssh.

But when I try to login again with the new password. I type the user name and the password but I cant get the prompt the terminal (putty) close.

I check the permissions on the file /etc passwd and group and on /etc/security and looks ok

Any ideas what could be the problem.

Thanks for your comments.

I guess the problem was resolve.

I added in /etc/passwd rksh, before was usr/bin/ksh and finished usr/bin/rksh

Im testing.

thanks anyway

Put the ksh shell for the user and check if the account is locked or not, and reset user login failed count.
If you need a hand with this, ask me, i think it could be a simple problem with a quick solution.
Then we can check PASSWD MAX AGE and other parameters.

Thanks for your help diesan
