Users come and users go and likewise user accounts get created and destroyed. However, sometimes your HR-processes fail and accounts get forgotten and left behind. It may not be obvious, but these forgotten accounts can actually form a threat to your security and should be cleaned up. Many companies even go out and lock or remove accounts of people who actively employed if they go unused for an extended period of time.
This script will help you find these forgotten user accounts, so you can then decide what to do with them.
./check_boks_dormant [[-u UC] [-H HG] [-h HOST] | -A] [-M MON] [-x UC] [-X HG] [-d -o FILE] [-f FILE] -u UCLASS Check only accounts with profile UCLASS. Multiple -u entries allowed. -H HGROUP Check only accounts from HOSTGROUP. Multiple -H entries allowed. -h HOST Check ALL accounts involved with HOST. Multiple -h entries allowed. -A Check ALL user accounts. -M MON Minimum amount of months that accounts must be dormant. Default is 6. -x EXCLUDEUC Exclude all accounts with profile UCLASS. Multiple -x entries allowed. -X EXCLUDEHG Exclude all accounts from HOSTGROUP. Multiple -X entries allowed. -S Exclude all accounts who can authenticate with SSH_PK. See "other notes" below. -f FILE Log file that contains all dormant accounts. Default logs into $BOKS_var. -d Debug mode. Provides error logging. -o FILE Output file for debugging logs. Required when -d is passed. When using the -h option, a list will be made of all user accounts involved with this server regardless of user class or host group. One can exclude certain classes or groups by using the -x and -X parameters. Example: ./check_boks_dormant.ksh -h solaris1 -x RootUsers -x DataTransfer ./check_boks_dormant.ksh -u OracleDBA ./check_boks_dormant.ksh -A -d -o /tmp/foobar
The script does not output to stdout. Instead, all dormant accounts are logged in $BOKS_var/check_boks_dormant.ksh.DATE or another file specified with -f.
The log file in $BOKS_var (or specified with -f) will contain a list of inactive accounts.
