Hi,
I’m using OpenLDAP backend with .NET 2.0 System.DirectoryServices.Protocols API in my application. I’m trying to issue PagedResult control as part of my request to get results in multiple pages that code can navigate. This would use rfc2696 which is already supported in OpenLDAP. But when I run my code it comes back with exception that ‘'critical control unavailable in context’.
I’ve attached the capture from OpenLDAP server
##
T 10.218.5.27:33236 -> 10.217.94.154:389 [AP]
0........c....s.!dc=openldap,dc=dev,dc=net6,dc=com.......................objectClass..person0.... ..distinguishedName..sn..manager...../0....)..1.2.840.1

#
T 10.217.94.154:389 -> 10.218.5.27:33236 [AP]
03...e...5...'critical control unavailable in context
#
But OpenLDAP does support the control 1.2.840.113556.1.4.319 as listed in my query response against rootDSE below

Any idea why the server responds with ‘'critical control unavailable in context’ message? I’m using OpenLDAP v 2.3.19
Not all of OpenLDAP's backends support all controls. Which backend are you using? It's probably easiest just to send your config file (slapd.conf, but remember to remove sensitive data like passwords!).
As a side note, 2.3.19 is now a very old version! You really should upgrade, at least to 2.3.43.
