HP-UX account locked out policy to be configured.

Hi,
I am having HP-UX 11i V1 running on PA-RISC servers. I have configured this default security on the system as below,
Server1:[/]# cat /etc/default/security
PASSWORD_MIN_UPPER_CASE_CHARS=1
PASSWORD_MIN_LOWER_CASE_CHARS=1
PASSWORD_MIN_DIGIT_CHARS=1
MIN_PASSWORD_LENGTH=8
PASSWORD_HISTORY_DEPTH=5
PASSWORD_MAXDAYS=90
PASSWORD_MINDAYS=1
PASSWORD_WARNDAYS=7

Server is not configured as trusted system.

Please can you let me know where do i have to do settings so that any user who try to login with is password and if he tries more than 3 times with wrong password account should get locked...

Thanks,
Narendra

Hey narendra,

These are system wide defaults in /etc/default/security which is at a global level for all users on that server.

What you are acheiving or trying to acheive is one of the reasons to go "trusted". I suggest you convert your system to a trusted system as this is one of the features of a trusted system compared to the normal legacy services or what is nicely termed as the passwd mode.

You may not be able to do all of these without being trusted or having shadow passwords.

Hi Dennis,
Please can you let me know where to do exactly the settings for Account locked out policy. As I am having shadow password software installed.

Server1:[/]# swlist |grep -i shadow
ShadowPassword B.11.11.03 HP-UX 11.11 Shadow Password Bundle

Thanks,

Shalom,

If you don't want to go trusted you must go with Shadow password depot (listed in an earlier post).

Your only other option is a scripted option that regularly scans the btmp file and locks out the user after a certain number of bad logins.

Outline:

cat /etc/passwd | awk -F: '{print $}'| while read -r un
do
blogs=$(strings /var/adm/btmp | grep $un | wc -l)
if [ $blogs -ge 3 ]
then

passwd -l $un
fi
done


You might want to enhance this script to perhaps send an email to someone to let them know the user is locked. I can help with that if you wish.
