Power Clear failed login count

What's actually the difference between these two command:
1) chsec -f /etc/security/lastlog -a "unsuccessful_login_count=0" -s username
2) chuser unsuccessful_login_count=0 username

Are there any impact on executing either one of those command to clear/reset the failed login count in AIX? Smilie

Or would it be better to just clear the failed login count using smitty? Smilie

can't tell the difference, but smitty uses this command:

Code:
chsec -f /etc/security/lastlog -a "unsuccessful_login_count=0" -s username

I run into this on a regular basis (dbas\developers constantly forgetting their passwords) so I have it scripted. You're more than welcomed to it:

Code:
#!/usr/bin/perl
#
# clrlogin
#
# description:  simple script to reset unsuccessful logins for a given user
#
#
###########################################################################

use strict;

# set some defaults
my $user;
my $ulogcnt;
my $ulogcntrst;

# check the command line
if(! @ARGV) {
        print "\nUsage: clrlogin 'username'\n\n";
        exit(1);
} elsif (($#ARGV+1) == 1) {
        # store the given username
        $user = shift @ARGV;
} else {
        print "\nIncorrect number of arguments!\n\n";
        exit(1);
}

# display the number of unsuccessful logins for the
# given user
$ulogcnt = `lssec -f /etc/security/lastlog -a "unsuccessful_login_count" -s $user`;
print "\n$ulogcnt\n\n";

# offer to reset unsuccessful logins to 0 or forgeddaboutit
print "Reset unsuccessful logins for $user? [y,n] ";
chomp(my $answer = <STDIN>);

if($answer =~ /^n$/i) {
        print "\nUnsuccessful logins not reset for $user.\n";
        exit(1);
} elsif ($answer =~ /^y$/i) {
        print "\nResetting unsuccessful logins for $user.\n";
        $ulogcntrst = `chsec -f /etc/security/lastlog -a "unsuccessful_login_count=0" -s $user"`;
        print "$ulogcntrst\n";
}

# done
exit(0);
