Sync control missing?

["Sean Loaring" <sloaring@gmail.com>]

Hello,

I've been working on some ldap client software that is supposed to make changes in some third party software whenever changes are made to certain ldap data.

I've been trying to get sync working with OpenLDAP, but the 1.3.6.1.4.1.4203.1.9.1.1 control seems to be missing.

Slapd version: 2.3.30-5+etch2

Output from ldapsearch -y $LDAP_PASSFILE -xW -D "$LDAP_USER" -b "" -s base '' supportedExtension supportedControl supportedFeatures

# extended LDIF

# base <> with scope baseObject
# filter: (objectclass=*)

Any light that anyone can shed on this would be appreciated.
