Yes: use a filter of '(cACertificate=*)' and do not require attribute
e.g., with the C API:

    char *attrs[] = { LDAP_NO_ATTRS, NULL };
    ldap_search(ld, NULL, LDAP_SCOPE_SUBTREE, '(cACertificate=*)', attrs, 1);

retrieves all the entries that have the attribute cACertificate, but no
Note: LDAP_NO_ATTRS="1.1" as per draft-ietf-ldapext-ldap-c-api-xx.txt
It is defined in ldap.h.
