A company has both local and LDAP users. Local users must be able to log in even if the LDAP server is unreachable. LDAP users should only be able to log in when the LDAP server is reachable. Which PAM configuration ensures this behavior?

Use only pam_unix.so in the auth stack

Place pam_ldap.so before pam_unix.so in the auth stack

Place pam_unix.so before pam_ldap.so in the auth stack

Use only pam_ldap.so in the auth stack

An administrator is troubleshooting LDAP authentication failures. The 'ldapsearch' command works correctly when using the service account credentials, but PAM authentication fails. Which diagnostic step is most likely to reveal the issue?

Check the /etc/hosts file for the LDAP server's hostname

Check the system logs for PAM and LDAP error messages

Verify that the LDAP server is reachable via ping
