Odd behavior from passwd.

Hi Folks,

Before I go off and start checking I'm just wondering if anyone has seen this behaviour before.

Code:
[root@fbakirpomd4 ~]# passwd e825390
Changing password for user e825390.
New password:
Retype new password:
Retype new password:
passwd: all authentication tokens updated successfully.

As you can see there is an extra "Retype new Password", the system is;
Code:
[root@fbakirpomd4 ~]# uname -a
Linux fbakirpomd4 3.10.0-862.el7.x86_64 #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux
[root@fbakirpomd4 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.5 (Maipo)
[root@fbakirpomd4 ~]#

The system has been built and a new "Security Standard" applied, this was done as a result of a "Security Audit" by a company called CGI.

This will cause an issue with a number of the standard accounts that we have on the servers going forward, the idea is to have a standard build so it has to be correct - one problem that I can foress is that the passwords are changed on the aforementioned accounts using an expect script and the second "Retype new Password" will break the script.

So I thought that I'd ask here before I raise an incident with Red Hat support.

Regards

Gull04

mkpwdict(1M)						  System Administration Commands					      mkpwdict(1M)

NAME
mkpwdict - maintain password-strength checking database SYNOPSIS
/usr/sbin/mkpwdict [-s dict1,... ,dictN] [-d destination-path] DESCRIPTION
The mkpwdict command adds words to the dictionary-lookup database used by pam_authtok_check(5) and passwd(1). Files containing words to be added to the database can be specified on the command-line using the -s flag. These source files should have a single word per line, much like /usr/share/lib/dict/words. If -s is omitted, mkpwdict will use the value of DICTIONLIST specified in /etc/default/passwd (see passwd(1)). The database is created in the directory specified by the -d option. If this option is omitted, mkpwdict uses the value of DICTIONDBDIR specified in /etc/default/passwd (see passwd(1)). The default location is /var/passwd. OPTIONS
The following options are supported: -s Specifies a comma-separated list of files containing words to be added to the dictionary-lookup database. -d Specifies the target location of the dictionary-database. FILES
/etc/default/passwd See passwd(1). /var/passwd default destination directory ATTRIBUTES
