Hi,

I set up an ldap server three years ago in our university in order to have a single password via samba and lib???-ldap.

Later on I requested an OID from IANA then created my own schema. It was working quite well.

A few months ago another organization's data was migrated to ldap (it is in testing now). In the meanwhile I switched to the latest openldap release (2.3). The older setup used ldbm backend the newer one is bdb based as ldbm is gone.

To get some kind of separation first I created two backends and with the help of an OpenLDAP core developer I set up slapo-glue to be able to search in both ldap suffix (needed for the mailserver which is the same for the two organization, other services are separated now). It was working, but I get weird timeouts on the mail server (it worked perfectly in the previous setup) and on the file server too. Syncrepl did not work at all so in order to get my replica back to work again I put all in one backend. Now I use a round-robin dns to distribute the load as before (slurpd replication).

I tuned the indices to avoid the timeouts and ran slapindex. I get no more index_param failed messages so I suspect all the needed indices are here. But the timeouts were still here.

My last hope was DB_CONFIG but it did not fix my problem. here is my DB_CONFIG: ----------------------------------- set_cachesize 0 134217728 2 #set_lg_regionmax 262144 #set_lg_bsize 2097152 #set_lg_dir /var/log/bdb # # Automatically remove log files that are no longer needed. set_flags DB_LOG_AUTOREMOVE # # Setting set_tas_spins reduces resource contention from multiple # clients on systems with multiple CPU's. set_tas_spins 1 -----------------------------------

I was unable to set up set_lg_* values right so they are commented out. I have 768Mb RAM. Debian Sarge. OpenLDAP 2.3 HEAD as 2006-09-25. libdb4.2.

I turned up loglevel and the message which annoyes me most is: <= bdb_index_read: failed (-30990) In db.h I found: #define DB_NOTFOUND (-30990)/* Key/data pair not found (EOF). */ but I do not know what does it mean in this context.

Please tell me what to do. Thanks in advance!
