"Pluggable Authentication Module." Programs that are aware of PAM use the modules defined in the PAM configuration files for making authentication/access decisions.

Remote Access Control

/etc/pam.d/sshd contains account required pam_access.so.
/etc/security/access.conf contains the rules for who can log into the machine.

/etc/pam.d/system-suth
Should contain these lines otherwise ssh among other service will not authenticate to einstein.
auth sufficient pam_ldap.so use_first_pass
account required pam_unix.so broken_shadow
account [default=bad success=ok user_unknown=ignore] pam_ldap.so
password sufficient pam_unix.so sha512 shadow nullok try_first_pass use_authtok
password sufficient pam_ldap.so use_authtok
session optional pam_ldap.so
