Description
Inactive identifiers pose a risk to systems and applications because attackers may exploit an inactive identifier and potentially obtain undetected access to the system. Owners of inactive accounts will not notice if unauthorized access to their user account has been obtained. SLES for vRealize need to track periods of inactivity and disable application identifiers after 35 days of inactivity.

Fix Text (F-42747r662115_fix)
Configure SLES for vRealize to disable account identifiers after "35" days of inactivity after the password expiration. Run the following command to change the configuration for useradd: Replace [VALUE] in the command with any integer from the range 0<[VALUE]<= 35. # sed -i "s/^.\bINACTIVE\b.$/INACTIVE=[VALUE]/" /etc/default/useradd DoD recommendation is "35" days, but a lower value is acceptable. The value "-1" will disable this feature and "0" will disable the account immediately after the password expires.

Configure SLES for vRealize to disable account identifiers after "35" days of inactivity after the password expiration. Run the following command to change the configuration for useradd:

Replace [VALUE] in the command with any integer from the range 0<[VALUE]<= 35.

# sed -i "s/^.*\bINACTIVE\b.*$/INACTIVE=[VALUE]/" /etc/default/useradd

DoD recommendation is "35" days, but a lower value is acceptable. The value "-1" will disable this feature and "0" will disable the account immediately after the password expires.
