>Description:
My daily mails have stoped reporting failed logins when there are failed logins in /etc/auth.log

I have traced this down as a formatting issue in the yestarday variable of /etc/periodic/800.loginfail

When egrep runs it is using the yesterday variable which reads: "May 7 "

The log files are being written to start "May  7 "

This causes the egrep to fail, thus not displaying any logs
>How-To-Repeat:
When I look at the syntax of the yestarday variable date command, it outputs the correct format when run from the command line.

/etc/periodic/security/800.loginfail:
yesterday=`date -v-1d "+%b %e"`
           -------------------

Script Output: "May 7"
Command Line Output: "May  7"
