NAME
    Authen::SASL::Authd - Client authentication via Cyrus saslauthd or
    Dovecot authentication daemon.

SYNOPSIS
        use Authen::SASL::Authd qw(auth_cyrus auth_dovecot);

        # authenticate user against Cyrus saslauthd
        auth_cyrus('login', 'passwd') or die "saslauthd: FAIL";

        # authenticate user against Dovecot authentication daemon
        auth_dovecot('login', 'passwd') or die "dovecot-auth: FAIL";

        # check user existence
        my %user_attr = user_dovecot('login', timeout => 3) or die "dovecot-auth: NO SUCH USER";
        print "user home: $user_attr{home}\n";

DESCRIPTION
    The "Authen::SASL::Authd" package implements LOGIN authentication
    protocol used by Cyrus saslauthd and PLAIN authentication protocol
    supported by Dovecot authentication daemon. It can be used to process
    authentication requests against configured SASL mechanism implemented by
    Cyrus or Dovecot SASL libraries. It can also be used to check if a
    particular user exists according to the Dovecot authentication daemon.

METHODS
    auth_cyrus( 'LOGIN', 'PASSWD', [ service_name => 'SERVICE_NAME', ] [
    timeout => 'TIMEOUT (sec)', ] [ socket => '/SOCK/FILE/NAME', ] )
    Check supplied user name and password against Cyrus saslauthd. Return
    true if authentication succeeded. Die in case of a likely configuration
    problem.

    auth_dovecot( 'LOGIN', 'PASSWD', [ service_name => 'SERVICE_NAME', ] [
    timeout => 'TIMEOUT (sec)', ] [ socket => '/SOCK/FILE/NAME', ] )
    Check supplied user name and password against Dovecot authentication
    daemon. Return true if authentication succeeded. Die in case of a likely
    configuration problem.

    user_dovecot( 'LOGIN', [ service_name => 'SERVICE_NAME', ] [ timeout =>
    'TIMEOUT (sec)', ] [ socket => '/SOCK/FILE/NAME', ] )
    Check if supplied user name exists according to the Dovecot
    authentication daemon. Return a reference to the hashtable (or the
    hashtable in list context) with optional user attributes if the user
    exists, undef (or empty list in list context) otherwise. The hashtable
    can contain such attributes as 'home', 'gid', 'uid', etc defined by the
    Dovecot SASL implementation. Die in case of a likely configuration
    problem.
