Re: System user login fails if ldap goes down.

Thanks for the information.

But is not working for me.

account     required      pam_unix.so broken_shadow
account     sufficient    pam_localuser.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     [default=bad success=ok user_unknown=ignore] pam_ldap.so
account     required      pam_permit.so

In Syslog (/var/log/secure) its keep on printing.

Accepted password for testuser from 1.2.3.4 port 46747 ssh2

Replace the above line with:
account sufficient pam_localuser.so

If you have pam_localuser.so available (you didn't mention which distro, but
it seems to be RH-derived).
