Hello,
I am setting up several openldap servers, and would like them to be synchronized, multi-master style.
Configuration : Version: 2.4.16 packaged by Symas OS: RedHat 5.3
I have tried following the Admin guide but for some reason, I just can't include the syncprov module.
How were you trying to "include the syncprov module" ? With 'moduleload syncprov.la' ? Was the modulepath set correctly? Can you provide some debug output from slapd showing what it tried?
When I add the line "overlay syncprov" in my slapd.conf file, slapd fails to start and i get this error message : Aug 6 17:29:21 localhost slapd[25880]: overlay "syncprov" not found
So, this means that the syncprov overlay was not found, it is most likely provided as a module. Not knowing exactly how Symas packages their binaries, I would run '"find /opt/symas -name 'syncprov*'" to try and find a module, or "objdump -T `find /opt/symas -name 'slapd'`|grep syncprov" to determine if syncprov is built in.
I found some information about this bug at https://bugzilla.redhat.com/show_bug.cgi?id=466937 , but i'm not sure whether it applies for symas'package : "syncprov is compiled statically into slapd daemon to keep backward compatibility"
No, the Red Hat people just made some bad decisions previously ...
I tried to skip this part, but as expected, replication doesn't work. I keep getting this message in logs. Aug 6 17:33:10 localhost slapd[25901]: slap_global_control: unrecognized control: 1.3.6.1.4.1.4203.1.9.1.1 According to a thread in this mailing list, this error appears when syncprov is not loaded in slapd.conf ( http://www.openldap.org/lists/openldap-software/200605/msg00277.html)
So here I am, stuck. I can't find syncprov.la in my module folder (/opt/symas/lib64/openldap), and I can't find any way to solve this problem.
Did I miss something ? How can i get this to work ?
There are other options for packages for Red Hat, such as:
http://staff.telkomsa.net/packages/rhel5/openldap/
(see http://staff.telkomsa.net/packages/OpenLDAP.repo)
Which ships syncprov as a module ... see the comments in the default slapd.conf.
Of course, as the Symas people usually say about Red Hat, contact the provider of your binaries for support :-p. I can't imagine that Symas would ship without syncprov, so you may want to consult any documentation they have provided if you haven't yet come right.
