Last signon info from omsearch

[eyalm]

Is there a way to run an omsearch that will return the last time a user logged in?
I know that omshowu does show that info, but I wanted to get a list of users that havent logged in in more than a month.

Thanks

omshowu -m all|while read i; do omshowu "$i"|grep User\ Name && omshowu "$i"|grep Last\ Signon && echo; done
