Hi Chris,
I'm not aware of anything special in my PAM configuration, I think It is still using the default configs.
user1 is a complete different user than any other, It has its unique user id.
If a create a brand new user, the same problem happens.
I could say I'm using the correct /etc/ssh/sshd_config because other changes to the file are read.
To be sure, as you can see at my last e-mail, I passed the -f command line option to run sshd.
The DenyUsers option is not working as well. I tried it with user1 and it does not block the user.
Below follow my /etc/pam.d/sshd, if you need any other file, please, let me know.
Thanks again for your help.
