Thanks for the suggestion.

No I didn't run the core with gdb.

Please see http://www.openldap.org/faq/data/cache/56.html.

In any case, you don't need sync_use_subentry, unless your database's suffix is "".

The owner of the files is root and I am running the slapd process with root only.

Have rearranged the directives in the config. Please check the attached. But it is still throwing the same error.

Can you please suggest on this?

Hi ,

I have added sync_use_subentry in the ldap configuration and it started throwing the core dump while performing the sync from other running server and stops the LDAP process.

Did you run the core within gdb?

...

Here is the error seen the in the debug logs.

<= index_entry_add( 114, "ou=New NetIQ StAlbans / Glasgow,ou=ChartReports,ou= services,o=BT" ) success

who is running slapd and who is the owner of dn2id.bdb and dn2entry.bdb?

...

send_ldap_result: conn=-1 op=0 p=0

send_ldap_result: err=10 matched="o=BT" text=""

error 10 indicates that the referral is not available.

Error 10 is there because the internal modification can't find the entry it's looking for, thus tries to send a referral according to updateref.

Have attached the slapd.conf file.

Could you please suggest?

Your slapd.conf is completely bogus, don't mix global configuration parameters with database specific parameters, and vice versa. Overlay declarations have to follow all database configuration parameters.

...

overlay syncprov syncprov-checkpoint 100 5 syncprov-sessionlog 100

sync_use_subentry TRUE

^^^^^^^^^^^^^^^^^^^^^^^^

this is a database specific parameter

...

# Index Definition

[...]

Indices are database specific

ACL's are partly global and database specific
