Check Text ( C-37120r3_chk )
If the "samba-common" package is not installed, this is not applicable. Check the encryption setting of Samba. # grep -i 'encrypt passwords' /etc/samba/smb.conf If the setting is not present, or not set to 'yes', this is a finding.

Fix Text (F-32388r1_fix)
Edit the "/etc/samba/smb.conf" file and change the "encrypt passwords" setting to "yes".
