Dear All , I face a problem as below environment.

a.) 4 x Openldap 2.4.8 which's config as N-Way Multi-Master.

b.) 4 x XEN Guest host Server running CentOS 5.1 & DB-4.6.21

c.) 4 x XEN Server running time sync every 5 min.

d.) Each of the Openldap Database stored information such as:

1. Postfix e-mail account / aliases config

2. Pam-LDAP account entry

3. E-mail Address Book

e.) All LDAP Server under the same Local Area Network

Config file which's N-Ray Multi-Master related.

/usr/local/etc/openldap/slapd.conf

For Host A = serverID1 = HOSTA.TEST.COM

For Host B = serverID2 = HOSTB.TEST.COM

For Host C = serverID3 = HOSTC.TEST.COM

For Host D = serverID4 = HOSTD.TEST.COM

Below is my case details.

1. There is no problems when I add / remove e-mail related information entry one by one. Each openldap Server could replicate information ( Add / Remove entry ) in short.

2. There is no problems when I add / remove PAM-LDAP login related infomation entry one by one. Each openldap Server could replicate information ( Add / Remove entry ) in short.

3. Thee is no problems when I add / remove e-mail address book entry one by one. each Openldap Server could replicate information ( Add / Remove entry ) in short.

Problems I found:

1. When I try to " mass import " E-mail address book from a LDIF file ( 200K LDIF entry which's include 1800 x cn entry ) on HOSTA , HOSTB / HOSTC / HOSTD only able to replicate around 600 ~ 1300 OR some times it could related all the 1800 entry of address book OR the openldap will shown as segment fault and services stop by itself.

2. If HOST A / B / C / D have 1800 LDAP Address book entry under ou=AddressBook,dc=test,dc=com , then I try to delete those 1800 entry. Host A could deleted those 1800 entry in short. But Host B / C / D can't replicate the entry that I delete on HOSTA by itself.

That's mean my N-Ray Multi-Master config can't 100% replicate itself database to the other database IF i " MASS INPORT " or " MASS DELETE " entry.

Question:

a) Is that normal for this case ?

b) I'm by using slapd.conf to STARTUP the slapd. And I also try to make use of -F /usr/local/etc/openldap/slapd.d to STARTUP the slapd. Both didn't have different, just want to know. If I am looking for N-Ray Multi-Master. By using slapd.conf OR slapd.d should be the best choice ?

c) What kind of log i should provide in this mail list could help for you all , and get help to debug my case ?

-d 256 OR -d 1024 while I startup the slapd ?

Many thanks for your create help , since N-Ray Multi-Master is new for me , so looking forward all of your help.

And looking forward all of your reply.

Thanks
