We compared the supportedControls attribute of a AD Simple AD and an UCS AD.
The UCS AD is missing 3 controls. One of them is marked as critical in the query:
controlType: 2.16.840.1.1137188.8.131.52 (LDAP_CONTROL_VLVREQUEST VLV)
As I understand it this control is a LDAP overlay (sssvlv). I tried to activate it by adding the line
to /etc/ldap/slapd.conf and restart the service. But it fails to start.
# /etc/init.d/slapd restart
[info] Restarting ldap server(s).
[ ok ] Stopping ldap server(s): slapd ...done.
[FAIL] Starting ldap server(s): slapd ...failed.

How do I activate this overlay/control?
