CfgTie::TieShadow -- an associative array of user names to password information


NAME

CfgTie::TieShadow -- an associative array of user names to password information


SYNOPSIS

This module makes the shadow database available as a regular hash.


DESCRIPTION

This is a straightforward hash tie that allows us to access the shadow password database sanely.

Ties

This tie is available for programmers:

tie %shadow,'CfgTie::TieShadow'

$shadow{$name} will return a hash reference of the named shadow information

Structure of hash

Any given shadow entry has the following information associated with it (the keys are case-insensitive):

Name
Login name

Password
The encrypted password

Last
Last time it was changed

Min
The minimum number of days before a change is allowed

Max
Maximum number of days before a change in passwords is required

Warn
The number of days before expiration that they will receive a warning

Inactive
The number of days before an account is inactive

Expires
The date the account expires on

Inactive
The number of days after a password expires that the account is considered inactive and expires

Each of these entries can be modified (even deleted), and they will be reflected in the overall system. Additionally, the programmer can set any other associated key, but this information will only available to the running Perl script.

Additional Routines

&CfgTie::TieShadow'status()
&CfgTie::TieShadow_id'status()
Will return stat information on the shadow database.

Miscellaneous

$CfgTie::Tiehadow_rec'usermod contains the path to the program usermod. This can be modified as required.

$CfgTie::TieShadow_rec'useradd contains the path to the program useradd. This can be modified as required.

$CfgTie::TieShadow_rec'userdel contains the path to the program userdel. This can be modified as required.

Caveats

The current version does cache some shadow information.
