Hi, I have an LDAP client(LDP.exe) trying to send a paged search to the LDAP server but get a result code of unavailableCriticalExtension(12), which seems to indicate that the Paged Results extension isn't present (or disabled???).
The OpenLDAP server is running slapd version 2.2.28, which according to the OpenLDAP roadmap should have the "Simple Paged Results Extension". http://www.openldap.org/software/roadmap.html
So the obvious question, does 2.2.28 support Paged Results? If it does, could it be the extension is disabled? How would I enable it?
Also, what is a good LDAP query to verify extensions like the Simple Paged Results?
Thanks in advance, NJM

I don't know in detail about 2.2.28, but OpenLDAP 2.2 should support that control when back-bdb is used. However I think nobody really bothers about checking such an outdated version (the current is 2.4.13).

a search with paged results control and criticality set to true will suffice.

It's not really by choice that I'm dealing with 2.2.28 unfortunately. What is back-bdb? I haven't been able to find any documentation on it.
Thanks for the help.

Then I don´t think you can find valuable help.

It´s the main storage of OpenLDAP since 2.X.

The bdb database backend, IOW, used as follows:
database bdb
If you have instead:
database ldbm
then you are using the ldbm backend, and you can expect: 1)Data corruption 2)Scalability problems 3)No database recovery options 4)No paged results
Switch to bdb (but, you should consider upgrading as well).

Thanks Buchan, you were of great help. It would appear this OpenLDAP server I'm working with is using their own database and backend (adm???), which explains why paging isn't working. Thanks again for your help.
