What version of Solaris do you use?  

What are the restrictions?  You can download the source from comsmiths.com.

You could possibly use scripts, but it wouldn't be the easiest of tasks.  Much better to use something that is known to work.

One way for sure to work without having to download 3rd party PAM modules is to updade to Solaris 10.  Automagic account lockout has finally been added to Solaris.  But I doubt upgrading Solaris was part of your plan ... ;D

We have Versions 8, 9 and 10 running in our environment.  Restrictions are mainly with regard to management approval.  I understand scripts are not easy but its worth a try...

Upgrade to 10??!! Now that will take a decade to get approved ;-)

Don't you love it when management place all these restrictions to make life more difficult.  They generally make these decisions based upon some vague concept that using third party or open source software is bad.

As for using scripts, the only way you could do it with standard tools is to interegate /var/adm/loginlog, but this only logs entries after 5 successive failed login attempts, so that may or may not be sufficient for your needs.

why don't you check the /etc/default/* files !
They are self explanatory with comments above each configurable parameter.

may be there you can find answers to what you need.

There are no Solaris options in the /etc/default/ files to lock an account.

My first solution works well providing you don't have brain dead management who refuse to install software that actually solves the problem.
