[morla <morla_(_at_)_10111_(_dot_)_hopto_(_dot_)_org>]

hello all,

i just made up a second account on my box and wanted to prevent the old 
one from loging into it, due i want to keep it for email retrival.

when i enter something like

 morla:*:1000:1000:morla:/home/morla:/sbin/nologin

into /etc/passwd and a similary entry into /etc/master.passwd should'nt 
this keep me out???

please be carefull with me, i am realtily new to bsd...


thanks all morla
