(ITS#5255) Outlook 2003 says: The search could not be completed.

Here's how Openldap was compiled:

PATH=/opt/SUNWspro/bin:/usr/bin:/usr/ccs/bin:/usr/sbin; export PATH

env CC=cc \
        INSTALL=/usr/ucb/install \
-I/usr/local/src/OpenSSL/openssl-0.9.8f/include" \
        LDFLAGS="-R/usr/local/lib -L/usr/local/src/db/db-3.1.17/build_unix
-L/usr/local/src/OpenSSL/openssl-0.9.8f/lib" \
        ./configure \
        --disable-proctitle \
        --enable-crypt \
        --disable-bdb \
        --disable-hdb \
        --enable-ldbm \
        --without-threads \

When using an ldbm database, Microsoft Outlook 2003 clients report this error
they attempt a search:

    The search could not be completed.  MAPI_E_CALL_FAILED

The LDAP logs show this message:

    critical control unavailable in context

This happens because Openldap advertizes the pagedResults control, even though
ldbm backend does not support it.  When OL 2003 obtains the list of available
controls, the LDAP server does not know which back end it will use.  When OL
does a query, it goes to the ldbm back end which does not support that control.
OL 2003 marks it critical, making the situation impossible.

In this situation, I'm using only the ldbm back end, so I removed the
control in servers/slapd/controls.c to fix the problem.  Here's my patch:

+ #ifdef VANILLA
                (int)offsetof(struct slap_control_ids, sc_pagedResults),
                SLAP_CTRL_SEARCH, NULL,
                parsePagedResults, LDAP_SLIST_ENTRY_INITIALIZER(next) },
+ #endif
  #ifdef LDAP_DEVEL
                (int)offsetof(struct slap_control_ids, sc_sortedResults),

Adding an access list to the config file did not work.
