Q67. According the following requirements, configure autofs service and automatically mount to user’s home directory in the ldap domain.
– Instructor.example.com (192.168.0.254) has shared /home/guests/ldapuserX home directory to your system by over NFS export, X is your hostname number.
– LdapuserX’s home directory is exist in the instructor.example.com: /home/ guests/ldapuserX
– LdapuserX’s home directory must be able to automatically mount to /home/ guests/ldapuserX in your system.
