NAME

Authen::Simple::IMAP - Simple IMAP and IMAPS authentication

SYNOPSIS

    use Authen::Simple::IMAP;

    my $imap = Authen::Simple::IMAP->new(
        host => 'imap.example.com',
        protocol => 'IMAPS',
    );

    if ( $imap->authenticate( $username, $password ) ) {
           # successful authentication
    }

     # or as a mod_perl Authen handler

     PerlModule Authen::Simple::Apache
     PerlModule Authen::Simple::IMAP

    PerlSetVar AuthenSimplePAM_host     "imap.example.com"
    PerlSetVar AuthenSimplePAM_protocol "IMAPS"

DESCRIPTION

Authenticate against IMAP or IMAPS services.

Requires Net::IMAP::Simple for IMAP and Net::IMAP::Simple::SSL for IMAPS. These modules are loaded when the object is created, not at compile time.

METHODS

• new

  This method takes a hash of parameters. The following options are valid:

  • host

    The hostname of the IMAP server

  • protocol

    Either 'IMAP' or 'IMAPS'. Any other value causes an exception. Selecting 'IMAPS' will cause an exception if Net::IMAP::Simple::SSL is not installed.

  • log

    Any object that supports "debug", "info", "error" and "warn".

            log => Log::Log4perl->get_logger('Authen::Simple::PAM')

  • escape_slash

    In some environments, a password containing a slash will fail unless the slash is escaped. Set escape_slash to true to escape slashes in passwords, or false to leave them unescaped. This is true by default.

  • imap

    Any object that supports "login" and "errstr" methods. The obvious choice being a Net::IMAP::Simple object, but if you want to use something else, here's how you can do it. This is how I use a mock imap object for the unit tests.

• authenticate( $username, $password )

  Returns true on success and false on failure.

DEPENDENCIES

Net::IMAP::Simple is required, and Net::IMAP::Simple::SSL is required for IMAPS. Net::IMAP::Simple::Plus adds some patches to the otherwise abandoned and broken Net::IMAP::Simple, so I recommend it.

BUGS AND LIMITATIONS

• I've never tried this in mod_perl, so including the mod_perl example in the synopsis is pure hubris on my part.
• The unit tests are pretty sparse. They don't include any tests against real IMAP servers. They just do a successful and failed password against a mock imap server object.
• This module uses Net::IMAP::Simple, which is broken and abandoned. I should either use something else or implement the IMAP stuff myself. I wound up wrapping the Net::IMAP::Simple stuff in an alarm+eval block to get it to behave.

CREDITS

• I pretty much ripped the best parts of this doc out of Christian Hansen's Authen::Simple::PAM and replaced "pam" with "imap" in a few places. The lousy parts are my own.
