Multi master replication

["Aravind Divakaran" <aravind.divakaran@yukthi.com>]

Hi All,

I have configured two servers with multi master replication. Below is my
configuration for synrepl on both servers.

Server One
------------

serverID 001

overlay syncprov
syncprov-checkpoint 100 10

syncrepl rid=000
  provider=ldap://192.168.10.100
  type=refreshAndPersist
  retry="5 5 300 +"
  searchbase="dc=example,dc=com"
  attrs="*,+"
  bindmethod=simple
  binddn="cn=syncuser,dc=example,dc=com"
  credentials=password

mirrormode TRUE

Server Two
--------------

serverID 002

overlay syncprov
syncprov-checkpoint 100 10

syncrepl rid=000
  provider=ldap://192.168.10.25
  type=refreshAndPersist
  retry="5 5 300 +"
  searchbase="dc=example,dc=com"
  attrs="*,+"
  bindmethod=simple
  binddn="cn=syncuser,dc=example,dc=com"
  credentials=password

mirrormode TRUE

Today one of user said that he was not able to login. So i checked in the
servers in one server i was able to login but on another server i was not
able to login with the same password. I have checked the contextCSN on
both server they are equal. In the log it is showing this

syncrepl_entry: rid=000 entry unchanged, ignored
(uid=user,ou=People,dc=example,dc=com)
Apr 28 12:14:17 mails slapd[16595]: syncrepl_entry: rid=000
uid=user,ou=People,dc=example,dc=com
Apr 28 12:14:17 mails slapd[16595]: syncrepl_entry: rid=000 be_add
uid=user,ou=People,dc=example,dc=com (68)
Apr 28 12:14:17 mails slapd[16595]: dn_callback : entries have identical
CSN uid=user,ou=People,dc=example,dc=com
20100422132507.789242Z#000000#002#000000

Can anyone help me why above message is showing in the log files and why
the user is not able to login.

Rgds,
