− Modify password file (defaulted to /etc/passwd) allows you to specify a different

user base.

− Modify command to be executed (defaulted to /usr/bin/passwd) allows you to

redefine the command to be executed instead of the password change utility.

− Modify keyword (defaulted to NODISP) allows you to specify a different keyword

for exclusion of certain users from the list.

− Modify regex (defaulted to /^root|[0-9]:[^:]*NODISP|x:0:/) allows you to redefine

the entire regular expression for exclusion of certain users from the list.

Please note, that all these options are hardcoded for security reasons. For example,

giving a user the opportunity to change the command to be executed might circumvent

the security settings established by

sudo. Similar arguments also apply to the other

options.

4 Requirements

pwdch is targeted to the Sun Solaris platform, version 2.x. We tested the application

successfully on Solaris 2.8.

pwdch relies on sudo to toggle normal and super user mode. sudo enforces a

centralized control over applications running in super user mode. This open source utility

may be downloaded from

www.sunfreeware.com at no charge. You have to install

sudo before using pwdch, otherwise pwdch won't be able to execute the passwd

command (or its replacement) as expected. Although there is no tight coupling between

sudo and pwdch, we recommend to use sudo 1.6.5 or above.

pwdch uses the C library curses for its window routines. As a consequence, the TERM

variable (or its equivalent in other shells) has to be defined properly. Furthermore you

should carefully select terminal emulation application and terminal type, as some

terminals do not allow for extended navigation such as <PGUP>, <PGDN> and

<HOME>. With raising number of users to be managed, lacking these navigation options

might result in dissatisfaction. We recommend AVAYA Terminal Emulator typically

provided with AVAYA products (the successor of Terranova Communications) and

terminal type set to AT&T605BCT.

5 Installation

This section covers the installation of the executables as well as the configuration of

sudo to pass temporary priviledges to the trusted user in charge of password

management. It also describes the process of adding a menu item to the CMS

application. Please note, that all applications shall be copied to the /usr/local

folder, as doing so reduces the problem of incompatibilities to a minimum. It also

prevents you from overwriting Solaris system components or CMS application files.

Most open source installations obey to this rule and so does sudo.

5.1 SUDO Installation

This section provides only a short overview of the sudo installation. Please refer to the

instructions delivered for details. After downloading the package from

www.sunfreeware.com (called sudo-1.6.7p5-sol8-sparc-local.gz or

similar), it first has to be decompressed by entering

# gzip –d sudo-1.6.7p5-sol8-sparc-local.gz
