/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
