Simple Paged Results Extension

[Ben Lentz <BLentz@channing-bete.com>]

Greetings, I have a third-party webmail client that queries corporate
contacts via LDAP. It was written specifically for an Exchange server. I get
the following errors from slapd when the client performs a query:
(OpenLDAP 2.1.22):
=> get_ctrls: oid="1.2.840.113556.1.4.319" (critical)
<= get_ctrls: n=1 rc=12 err="critical extension is not recognized"
send_ldap_result: conn=0 op=0 p=3
send_ldap_result: err=12 matched="" text="critical extension is not
recognized"
send_ldap_response: msgid=1 tag=101 err=12

(OpenLDAP 2.2.5):
=> get_ctrls: oid="1.2.840.113556.1.4.319" (critical)
=> get_ctrls: oid="2.16.840.1.113730.3.4.2" (noncritical)
<= get_ctrls: n=2 rc=0 err=""
send_ldap_result: conn=0 op=0 p=3
send_ldap_result: err=12 matched="" text="control unavailable in context"
send_ldap_response: msgid=12 tag=101 err=12

I've got no control over the client software and no longer want to use
Exchange. I believe an OpenLDAP solution would be superior. Any help anyone
can provide would be much appreciated.
