Kadmin keytabs keytab Heimdal API kadmind kadmin
=head1 NAME
Wallet::Kadmin - Kadmin module wrapper for wallet keytabs
=head1 SYNOPSIS
my $kadmin = Wallet::Kadmin->new ();
$kadmin->addprinc ("host/shell.example.com");
$kadmin->ktadd ("host/shell.example.com", "aes256-cts-hmac-sha1-96");
my $exists = $kadmin->exists ("host/oldshell.example.com");
$kadmin->delprinc ("host/oldshell.example.com") if $exists;
=head1 DESCRIPTION
Wallet::Kadmin is a wrapper to modules that provide an interface for
keytab integration with wallet. Each module is meant to interface with a
specific type of Kerberos implementation, such as MIT Kerberos or Heimdal,
and provide a standard set of API calls used to interact with that
implementation's kadmin interface.
The class simply uses Wallet::Config to find which type of kadmind we have
requested to use, and then returns an object to use for interacting with
that kadmind.
A keytab is an on-disk store for the key or keys for a Kerberos principal.
Keytabs are used by services to verify incoming authentication from
clients or by automated processes that need to authenticate to Kerberos.
To create a keytab, the principal has to be created in Kerberos and then a
keytab is generated and stored in a file on disk.
To use this object, several configuration parameters must be set. See
Wallet::Config(3) for details on those configuration parameters and
information about how to set wallet configuration.
=head1 METHODS
=over 4
=item new()
Finds the proper Kerberos implementation and calls the new() constructor
for that implementation's module, returning the result. If the
implementation is not recognized or set, die with an error message.
