I attempted to create an new user account that I wish to use to log in using ssh.

I did this (in CentOs):

/usr/sbin/adduser -d /home/testaccount -s /bin/bash user
passwd testaccount 

This is the error I receive when trying to log in via ssh:

~/.ssh$ ssh -v testaccount@xxx.xxx.xxx.xxx

The "connection closed" message appeared immediately after entering the password (if I enter the wrong password it waits and then prompts for another password)

I am able to log in from the same computer using other accounts that had been setup previously.

When logged into the remote machine I am able to do 'su testaccount'

Thanks for your time.

Please try with a command like ssh -v testaccount@xxx.xxx.xxx.xxx /bin/sh and tell us if there's something different. –  jneves Jun 11 '10 at 9:08
    
I tried adding the /bin/sh to the end of the command, but I got the messages as above. –  Michael B Jun 15 '10 at 23:41

I just needed to add this line to /etc/security/ssh_users:

+:testaccount:ALL

Please mark this answer as correct. Thank you! –  Chris S Jun 24 '10 at 1:53

The last message seems to indicate that you're using kerberos and that the failure was on the kerberos side. Do you have any more information, for instance, in /var/log/auth.log or other kerberos related files?

/var/log/auth.log doesn't exist. According to the kerberos config at /usr/krb5.conf, the log file is at /var/log/krb5libs.log, but that doesn't exist either. Thanks for you help. –  Michael B Jun 11 '10 at 2:42
