17. Migrating Linux Users to LDAP



Learn all about risk management and IT governance for the CAS-003 exam.

 

 

This course covers the security topics relative to the CASP+ Certification domain of risk management and IT Governance. In this course, the student will obtain the knowledge and skills needed to pass the CASP+ Certification exam as they relate to this specific domain. This course is one of five domains covered by the CAS-003 exam.

In this lab, we go through the process of adding a Linux user and then using a migrate utility to create an LDIF file that facilitates the use of the `ldapadd` command to add the user to an LDAP directory. Learning Objectives Successfully complete this lab by achieving the following learning objectives: Connect to the LDAP Server and the Linux Server Connect to each server: ssh cloud_user@ Provide the appropriate password from the lab interface. Verify the Installation of LDAP on the LDAP Server On the LDAP Server Check the version of LDAP that has been staged: slapd -VV Verify the slapd daemon is running and active: sudo systemctl status slapd Provide the cloud_user password for the LDAP server. Search the existing LDAP database: ldapsearch -x -LLL -b dc=example,dc=com Set the Password for the LDAP Server On the LDAP Server Generate an encrypted password: slappasswd Copy the output from that command into the clipboard and save it. Use a Linux text editor to add the encrypted password to the slapd configuration file: sudo vi /etc/openldap/slapd.d/cn=config/olcDatabase={2}hdb.ldif Change the line that starts with olcRootPW, replacing the existing string after the colon with the encrypted password you just copied. After saving the configuration file, restart the service: sudo systemctl restart slapd Add a Linux User and Migrate the User to LDAP On the LDAP Server Add a Linux user: sudo useradd sudo passwd Respond with a password. Grab the user and group lines from /etc/passwd and /etc/group, and output them to text files: grep /etc/passwd > ./passwd.txt grep /etc/group > ./group.txt Use the migration utility to convert the Linux text into ldif format: /usr/share/migrationtools/migrate_passwd.pl ./passwd.txt ./passwd.ldif /usr/share/migrationtools/migrate_group.pl ./group.txt ./group.ldif Look at the files you have created: cat ./passwd.ldif cat ./group.ldif Add the ldif data to the directory: ldapadd -x -W -D "cn=Manager,dc=example,dc=com" -f ./passwd.ldif ldapadd -x -W -D "cn=Manager,dc=example,dc=com" -f ./group.ldif Search the directory to determine the contents: ldapsearch -x cn= -b dc=example,dc=com Verify the User You Added Is Available from the LDAP Client From the server configured as an LDAP client: id
