Argh.  I seem to be finding the exact opposite.  I segfault when I use
LDAP_NO_ATTRS.  Here's the gdb bt output:

Program received signal SIGSEGV, Segmentation fault.
0x40331acd in ber_put_string () from /usr/lib/liblber.so.2
(gdb) bt
#0  0x40331acd in ber_put_string () from /usr/lib/liblber.so.2

#4  0x40310cd1 in ldap_search_ext_s () from /usr/lib/libldap.so.2

I'm assuming the ber struct in ldap_search_ext is causing problems when
being freed or something.

However, if I do char *attributes[] = {"dn", NULL}; and use that instead of
LDAP_NO_ATTRS, it doesn't segfault; it works fine.

Here's the offending function call:

ldap_search_ext_s(ld, ldap_basedn, LDAP_SCOPE_SUBTREE, filter,
                          LDAP_NO_ATTRS, 0, NULL, NULL, LDAP_NO_LIMIT, 1,

(yes, i'm checking return types, but I'm just simplifying this here.)
