Project 1 DAVE3610 Nettverks- og systemadministrasjon Spring 2017 The ​DAVE3610 ​ University wants to implement a centralized account management such that all the users created whether they are staff, student are managed centrally. The University policy is to only use open standards and avoid proprietary solutions. The IT department has been given a task to build a solution based on Open Source technologies with the following specifications. The system must implement: ● a scalable ​LDAP ​ server: ○ OpenLDAP ​ is the required ​LDAP ​ server for the University. ○ a user should be able to login with the same username and password from any Linux machine. ○ This includes the ​LDAP ​ server as well. In other word the LDAP server must be configured as an ​LDAP ​ client ● a quota that limits all the users except ​root ​ and ​sysadmin ​ to ​500 MB ​ of disk space. As the newly recruited system administrator you receive an email from the senior system administrator asking you to carry out the following: Hi Junior Sysadmin, We want you to prepare a VirtualBox virtual machine and setup a centralized account management based on LDAP according to the following requirements: ● Download and import the VirtualBox virtual machine from: ○ http://ismail.cs.hioa.no/dave3610/2017/Projects/Projects.ova ○ YOU ARE NOT ALLOWED TO USE ANY OTHER OVA IMAGE PERIOD!! ● The ​OVA ​ image contains an XUbuntu ​16.04 ​ image with ​5 ​ disks four of which do not contain any partitions, filesystems or data. ● Change and configure the ​hostname ​ in ​/etc/hostname ​and ​/etc/hosts ​ to your candidate number: ○ You can find your candidate number i Fronter: ● Partition the ​4 ​empty disks as type​ Linux Raid. ● Create a ​RAID level 5 ​ called ​/dev/md0 ​ with a hot-spare. ○ NB! Make sure that ​/dev/md0 ​does not change upon reboot ● Create an Physical Volume on ​/dev/md0 ● Create a Volume Group called ​dave3610 ​ on ​/dev/md0● Create a Logical Volume with a size of ​2 GB ​ on the Volume Group ​dave3610 and give it a name that is the same as the ​hostname. ​This must also be the same as your candidate number ● Create an ​ext4 ​ filesystem on the newly created logical volume ● Create the directory ​/mnt/homedir ● Mount the newly created ​ext4 ​ filesystems on ​/mnt/homedir ● To mount the filesystems permanently upon startup/reboot, edit the file ​/etc/fstab and add the the appropriately settings. ● Setup an ​OpenLDAP ​ server and make sure that it uses: ○ suffix ■ dc=dave3610,dc=com ○ rootdn ■ cn=admin,dc=dave3610,dc=com ○ rootpw ■ pagh3377 kryptert som {SSHA} ● Create the following ​organizationalUnit ​ in ​OpenLDAP ​: ○ People ○ Groups ● Create the following groups in the ​organizationalUnit ​ Groups: ○ grp1 ​ with GID 4000 ○ grp2 ​ with GID 5000 ● Create the following users in the organizationalUnit People ○ user1 ​ with UID 4000, GID 4000, homeDir ​/mnt/homedir/user1 ○ user2 ​ with UID 5000, GID 5000, homeDir ​/mnt/homedir/user2 ○ Give both users the password ​pagh3377 ● Setup ​quota ​ that limits all the users except ​root ​ and ​sysadmin ​ to ​100 MB ​ of disk space. ● Once the implementation is complete and well tested, do the following: ○ Turn off the virtual machine. ○ Make a clone of the virtual machine and continue doing ​Project 2 ○ NB! You will find more information on how to deliver the projects in Project 2.
