Hi,

Is a useful way to lock user access without involve password field. e.g:
#usermod -s /usr/bin/false xyz

To work, also you must include once this entry in /etc/shells file:
/usr/bin/false

The /usr/bin/false file must exist, old HP-UX 11 versions not include this file, then create it:
#echo "exit 0" > /usr/bin/false and set adecuated ownwership and privileges.

Hi,

The shell /usr/bin/false is widely seen in the "system account" tftp which is the priveleged account on /etc/passwd for the protocol tftp.
