Fix Recommendation

Install the sssd.service and the required pam packages with the following commands:

$ sudo apt install sssd

$ sudo apt install libpam-sss

$ sudo apt install libnss-sss

Check Contents

Verify Ubuntu 22.04 LTS has the packages required for multifactor authentication installed with the following command:

$ dpkg -l | grep sssd
ii sssd 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- metapackage
ii sssd-ad 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Active Directory back end
ii sssd-ad-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- PAC responder
ii sssd-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- common files
ii sssd-ipa 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- IPA back end
ii sssd-krb5 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Kerberos back end
ii sssd-krb5-common 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- Kerberos helpers
ii sssd-ldap 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- LDAP back end
ii sssd-proxy 2.9.4-1.1ubuntu6.1 amd64 System Security Services Daemon -- proxy back end

If the "sssd" package is not installed, this is a finding. The additional sssd components listed by the command may differ from configuration to configuration.

Verify that "libpam-sss" (the PAM integration module for SSSD) is installed with the following command:

$ dpkg -l | grep libpam-sss
i libpam-sss:amd64 2.9.4-1.1ubuntu6.1 amd64 Pam module for the System Security Services Daemon

Verify that "libnss-sss" (the NSS module for retrieving user and group information) is installed with the following command:

$ dpkg -l | grep libnss-sss
ii libnss-sss:amd64 2.9.4-1.1ubuntu6.1 amd64 Nss library for the System Security Services Daemon

If "libpam-sss" and "libnss-sss" are not installed, this is a finding.
