(ITS#8867) ldap_sasl_bind_s failed error during replication

Full_Name: anil kumar appanna Version: 2.4 OS: RHEL URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (143.112.32.4)

I configured multi master replication. The configuration went well without any errors, but the data is not replicated from one server to another one. When i looked at the log file, i am getting the below errors

slap_client_connect: URI=ldap://***.com DN="cn=config" ldap_sasl_bind_s failed (-1) do_syncrepl: rid=001 rc -1 retrying slap_client_connect: URI=ldap://***.com DN="cn=ldapadm,dc=****,dc=com" ldap_sasl_bind_s failed (-1)

appreciate any quick help. I am very new to openldap.
