178 The Virtualization Cookbook for RHEL 6 ¦ ¦ ¦ [ ] Use TLS ¦ ¦ Server: ldap://9.60.18.225______________________ ¦ ¦ Base DN: dc=my-domain,dc=com_____________________ ¦ ¦ ¦ ¦ -------- ------ ¦ ¦ ¦ Back ¦ ¦ Ok ¦ ¦ ¦ -------- ------ ¦ ¦ ¦ ¦ ¦ ----------------------------------------------------¦ Your LDAP client should now be pointing to the LDAP server. Test it with the id ldapuser1 command: # id ldapuser1 uid=500(ldapuser1) gid=500(ldapuser1) groups=500(ldapuser1) context=root:system_r:unconfined_t:s0-s0:c0.c1023 In RHEL 6, you can no longer authenticate over SSH without using TLS. This section has not described how to set up TLS. To do that, you would need a signed certificate that corresponds to your enterprise’s DNS domain name. There is some information at the OpenLDAP Web site. http://www.openldap.org/pub/ksoper/OpenLDAP_TLS.html More details on the cn=config/ directory repalcing the /etc/openldap/slapd.conf file is on the following Red Hat Web site (you need a subscription to get to it): https://access.redhat.com/kb/docs/DOC-3637 11.3 Creating a virtual file and print server Samba allows Windows clients to map Linux file systems as shared drives. Samba can also act as a middle-man between Windows clients and a Linux print server. The recommended Linux print server is CUPS - the Common UNIX Printing System. This section does not describe the configuration of CUPS but it does describe how the necessary RPMs are installed. The steps in this section are as follow: ► “Cloning a Linux virtual server” on page 178 ► “Installing necessary RPMs” on page 179 ► “Configuring Samba configuration file” on page 179 ► “Adding a Samba user” on page 180 ► “Starting Samba at boot time” on page 180 ► “Testing your changes” on page 180 11.3.1 Cloning a Linux virtual server To clone a newLinux server, perform the following steps: ► Start an SSH session as root to the cloner. ► Copy a Linux cloning configuration file and modifying the IP address and host name variables: # cd /etc/clone # cp linux01.conf linux03.conf
# vi linux03.conf // ... modify IPADDR and HOSTNAME variables ► Clone a basic virtual server. In this example the user ID LINUX03 is used. # clone -v rh6gold linux03 Invoking CP command: QUERY rh6gold Invoking CP command: QUERY linux03 This will copy disks from rh6gold to linux03 Host name will be: 6.endicott.ibm.com IP address will be: 9.60.18.224 Do you want to continue? (y/n): y ... ► When the new system comes up, start an SSH session to the new virtual server. 11.3.2 Installing necessary RPMs Add the following RPMs with the yum -y command: # yum -y install samba ... Installed: samba.s390x 0:3.5.4-68.el6 Confirm that the RPMs were added: # rpm -qa | grep samba samba-common-3.0.28-0.el5.8 samba-client-3.0.28-0.el5.8 samba-3.0.28-0.el5.8 samba-common-3.0.28-0.el5.8 11.3.3 Configuring Samba configuration file The one configuration file for Samba is /etc/samba/smb.conf. It is easy to add an SMB share that will be made available by the Samba server. A good test directory is /usr/share/doc/ as it has much good Linux documentation. The following example will create a file share named sharedoc: # cd /etc/samba # cp smb.conf smb.conf.orig # vi smb.conf // add three lines at the bottom of the file: ... [sharedoc] comment = RHEL 6 on System z documentation path = /usr/share/doc/ You can verify the syntax of your changes with the testparm command: # testparm smb.conf Load smb config files from smb.conf Processing section "[homes]" Processing section "[printers]" Processing section "[sharedoc]" Loaded services file OK.
