• ulimits (/etc/login.conf)

Edit the /etc/login.conf so that the staff class has the proper settings. The following is a working example of the staff class:

staff:\
       :datasize-cur=infinity:\
       :datasize-max=infinity:\
       :datasize=infinity:\
       :openfiles-cur=4096:\
       :maxproc-max=512:\
       :maxproc-cur=512:\
       :ignorenologin:\
       :requirehome@:\
       :tc=default:

After editing the login.conf you'll need to rebuild the database with:

# cap_mkdb /etc/login.conf

ulimit -n 512
ulimit -p 512
ulimit -d 2036792

Add the login class to the user you would like to have build go

# vipw

Look for the 5th element which is the login class, this is blank by users added by useradd. In the following example the user operator would be added to the staff class

## Before
operator:*:2:5::0:0:System &:/operator:/sbin/nologin

## After
operator:*:2:5:staff:0:0:System &:/operator:/sbin/nologin
