Hi,

I'm a bit in dead end. Scenario: Active Direcotory & openldap (2.4.33) proxy. Paged search through proxy is not working.

I'm not sure about this OID "1.2.840.113556.1.4.1339". OpenLdap ldap.h tells that this oid is LDAP_CONTROL_X_DOMAIN_SCOPE. According to O'Reilly AD cookbook: "No referrals generated" with longer description "Informs the server not to generate any referrals in a search response". May this be the reason for paged search to fail? Same query runs without any problems directly within Active Directory domain controller's. As i read from google, it should be possible to make paged search work, but i can't figure it out how.

eimar@box: /tmp > ldapsearch -LLL -H ldaps://olp-test.example.ee -P 3 -E pr=500/noprompt -D "CN=ldap-auth,CN=Users,DC=example,DC=ee" -W -b "ou=workers,dc=example,dc=ee" "(objectClass=person)" samaccountname -s sub > results.txt Enter LDAP Password: Size limit exceeded (4)

eimar@box: /tmp > grep dn: results.txt | wc -l 1000

which is the default search limit in AD.
