Need help syncing with syncrepl 2.3
by L.B. 20 May '10

20 May '10

Hi; I've finally decided to make the move to syncrepl after much delay and procrastination. I've read the guide and also reviewed several howto's on the topic... It still isn't running correctly for me because it doesn't replicate a few new users I've added to the provider. Also I'm seeing the following issue over and over (every time it tries a sync on my 10m interval): ######### Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: do_syncrep2: rid 001 LDAP_RES_INTERMEDIATE - SYNC_ID_SET Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: syncrepl_del_nonpresent: rid 001 be_delete uid=airftp,ou=SystemUsers,ou=SystemAccounts,dc=swa,dc=com (0) Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: syncrepl_entry: rid 001 LDAP_RES_SEARCH_ENTRY(LDAP_SYNC_ADD) Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: syncrepl_entry: rid 001 be_search (0) Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: syncrepl_entry: rid 001 uid=airftp,ou=SystemUsers,ou=SystemAccounts,dc=swa,dc=com Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: syncrepl_entry: rid 001 be_add (0) Mar 5 20:25:19 admin-agis01 slapd2.3[6147]: do_syncrep2: rid 001 LDAP_RES_SEARCH_RESULT ######### My setup is RHEL4 with Buchan's RPMs (openldap2.3-servers-2.3.39-3.rhel4, etc.).

Slave connecting to maser always stay connected?
by Mathew Rowley 13 Apr '10

13 Apr '10

I have a setup with 2 masters (nway multimaster) and 4 slaves each having syncrepl set up to connect to the 2 masters. The question I have, with the following configuration (on the slaves) should they always be connected to the masters? Netstat is showing that the connections are intermittent: type=refreshAndPersist retry="60 +" Netstat on the masters shows that the connections from the slaves will vary sometimes 0, sometimes 4 seems to be somewhat random. We are trying to determine if there is something wrong in our network. Thanks for the help. MAT

You can try basic tuning (via DB_CONFIG for Berkeley DB) and the cachesize. But some of the options for tuning available in later releases are not valid for 2.2. For running a production LDAP service, I near always recommend building and maintaining it yourself. --Quanah -- Quanah Gibson-Mount Principal Software Engineer Zimbra, Inc -------------------- Zimbra :: the leader in open source messaging and collaboration

Syncrepl loosing synchronization
by Massimo Lusetti 31 Mar '10

31 Mar '10

Hi all, I have 6 servers which all synchronize with syncrepl mechanism from a single master. Of that six server one is the master and 2 are local connected servers, every server is a 2.4, plus there are 3 remote connected servers which are all 2.3 With local connected i mean LAN (maybe different DMZ) while remote connected i mean WAN (with data over the relative-slow link). It happens frequently that the remote servers loose synchronization with the master (no more updates to data) when/if the link goes down. Or even when the link is slower the usual. The local connected servers are all with refreshAndPersist while the remotes one are refreshOnly. Every replica has a retry of "60 +" so it tries indefinitely and the refreshOnly ones has an interval of 45 Did you have any clues while is should loose synchronization and the only possible solution is to rebuild the whoile DIT on the replicas? Cheers -- Massimo

architecture and DIT change strategy
by Guillaume Rousse 31 Mar '10

31 Mar '10

Hello. I'm trying to find the best way to conduct a consequent change in our data model and servers topology, with the fewer service disturbing. Before the reorganisation, we were a single entity, splitted on three different sites. As a consequence, we had a single database for all our users and groups: dc=new,dc=foo,dc=tld |-users | |-site1 | |-site2 | |-site3 |-groups |-site1 |-site2 |-site3 The master server is hosted on one site, and we have slave servers on three sites After the reorganisation, we are three different entities, and I'd like to break the tree in the three different databases, each site hosting a server acting as the master for its own base, a slave for the two others: dc=site1,dc=foo,dc=tld |-users |-groups dc=site2,dc=foo,dc=tld |-users |-groups dc=site3,dc=foo,dc=tld |-users |-groups The change also involves dropping the last part of the original suffix, which is no longer relevant. I'm currently investigating the usage slapo-rwm to provide virtual views of the current database according to the new structure, so as to progressively migrate applications configuration first, then write an automated conversion tool, and finally convert the virtual bases to new ones. But maybe they are better strategies ? -- BOFH excuse #193: Did you pay the new Support Fee?

Please stay on the mailing list. Itay Moav wrote: > yes - only the hard coded ones (as I figured where to find and read the > schema files that comes with the installation :-) ) Do not include schema files and start slapd with all the overlays you need. Then look at the subschema subentry. Ciao, Michael.

My original config had :- type refreshOnly interval 00:00:05:00 and it needed to be :- type=refreshOnly interval=00:00:05:00 Fixed these and replication is working fine using 2.3. At least so far anyway. I'm using the version which comes with RedHat 5.3 which shows as 2.3.43-3 Steve -- http://ournaturalway.co.uk

It seems like a name canonicalisation error for me, as you have a multihomed setup, and result varies with the IP adress you're using. You have to ensure the principal used in LDAP server keytab (its SPN) matches both the ones used by client when they ask a service ticket (DNS hostname for the IP adress used in their /etc/openldap/ldap.conf files), and the one used by the server itself (by default, the one returned by gethostname(), otherwise, the one specified with sasl_hostname directive in its configuration file). You may also check in the KDC logs what are the principal requested by clients. -- BOFH excuse #11: magnetic interference from money/credit cards
