    Hello,

    in dict_ldap.c (postfix-1.1.11-20020822 and older snapshots) there's a
    call to ldap_get_option with incorrect parameters. It gets invoked
    when verbose logging is enabled:

    dict_ldap.c (dict_ldap_connect, line 307):
            ldap_get_option(dict_ldap->ld,
                        LDAP_OPT_PROTOCOL_VERSION, (int *) dict_ldap->version))

    Note the last parameter.

    In openldap-2.0.25/libraries/libldap/options.c this function is
    defined as
            ldap_get_option(
                    LDAP *ld,
                    int option,
                    void *outvalue)

    Casting dict_ldap->version to a pointer does not yield a valid pointer
    to store something at and e. g. "smtpd -v" crashes at startup (provided
    that it uses ldap maps).

    One possible solution for this problem is attached below.

    Regards,
    Norbert
