Re: Integrated Login


Following your advice I have successfully setup integrated login for ssh.
I got both AFS token and Kerberos 5 ticket.

Following are the PAM files of sshd and system-auth:
I have a few questions regarding the setup of sshd PAM file that looks a little strange for me although it's working and satisfy my needs.


auth       required     pam_listfile.so item=user sense=deny file=/etc/ssh/ssh_host_deny ># Without the following line it's not working properly ( I wonder why, it has the same line in system-auth file )
auth       required     pam_afs.so try_first_pass ignore_root set_token
# Note that the following line is marked as optional, any change will harm the login process - I think it should be required
auth       optional     pam_stack.so service=system-auth
auth       required     pam_nologin.so

account    required     pam_stack.so service=system-auth

password   required     pam_stack.so service=system-auth

session    required     pam_stack.so service=system-auth
session    required     pam_limits.so


auth        required      pam_env.so
auth        optional      pam_krb5.so use_first_pass
auth        required      pam_afs.so try_first_pass ignore_root set_token
auth        required      pam_deny.so

account     sufficient    pam_unix.so
account     sufficient    pam_krb5.so
account     sufficient    pam_ldap.so

password    requisite     pam_passwdqc.so min=disabled,8,8,8,8 passphrase=0 enforce=users
password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
password    sufficient    pam_krb5.so use_authtok
password    required     pam_deny.so

session     required      pam_limits.so
session     optional      pam_krb5.so
session     optional      pam_ldap.so
session     required      pam_unix.so

This module must be "required" and not "sufficient".

Also you shouldn't use full paths to the modules, the pam library will
search /lib(64)/security automatically.
