ok, but are not there a default log file locally for this ? am i neccesary obliged to make a script before ?

This is not clear enough. The fact that a password is changed is noted in /etc/security/passwd, a file in stanza format, with a lastupdate= entry. Note that this only pertains to locally authenticated users. LDAP-, Kerberos-, ... -users where the AIX system relies on some external system for the authentication do not have password-information on the system and therefore no pasword-update-information.

You might want to read up about "LAM" ("loadable authentication modules") for details.

That depends on what you want to know. The lsuser command provides information about the attributes "unsuccessful_login_count". "host_last_unsuccessful_login" and some others (issue lsuser root as root for a complete list of user attributes). You can also configure some authentication mechanisms to use the syslog facilities to write logs. There is nothing out of the box, though, because "authentication" is a loadable, configurable and quasi-external service for AIX.

Is logged in the error log. As a root user enter errpt for an overview and errpt -a for a detailed description of every entry (including shutdown/boot events).

ok, thks
I hope this helps.

PAM_KSU(8)						    BSD System Manager's Manual 						PAM_KSU(8)

NAME

     pam_ksu -- Kerberos 5 SU PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_ksu [options]

DESCRIPTION

     The Kerberos 5 SU authentication service module for PAM, pam_ksu for only one PAM category: authentication.  In terms of the module-type
     parameter, this is the ``auth'' feature.  The module is specifically designed to be used with the su(1) utility.

   Kerberos 5 SU Authentication Module
     The Kerberos 5 SU authentication component provides functions to verify the identity of a user (pam_sm_authenticate()), and determine whether
     or not the user is authorized to obtain the privileges of the target account.  If the target account is ``root'', then the Kerberos 5 princi-
     pal used for authentication and authorization will be the ``root'' instance of the current user, e.g. ``user/root@REAL.M''.  Otherwise, the
     principal will simply be the current user's default principal, e.g. ``user@REAL.M''.

     The user is prompted for a password if necessary.	Authorization is performed by comparing the Kerberos 5 principal with those listed in the
     .k5login file in the target account's home directory (e.g. /root/.k5login for root).

     The following options may be passed to the authentication module:

     debug	     syslog(3) debugging information at LOG_DEBUG level.

     use_first_pass  If the authentication module is not the first in the stack, and a previous module obtained the user's password, that password
		     is used to authenticate the user.	If this fails, the authentication module returns failure without prompting the user for a
		     password.	This option has no effect if the authentication module is the first in the stack, or if no previous modules
		     obtained the user's password.

     try_first_pass  This option is similar to the use_first_pass option, except that if the previously obtained password fails, the user is
		     prompted for another password.
