Mirror Mode question

[Ivan Ordonez <iordonez@nature.berkeley.edu>]

Hi,  I am trying to setup mirror mode on two identical machines.  
Previously, these two machine were setup as PDC and BDC, using syncrepl 
provider and comsumer method.  All changes are done through the PDC, and 
will sync to BDC.  We decided to use mirror mode for high availability 
but having issue getting it to work.  When I try to create an account, I 
will get an error message regarding smbldap-tools.  See below.

Error: shadow context; no update referral at /usr/sbin//smbldap_tools.pm 
line 1083, <DATA> line 466.

Is there anything on smbldap.conf that I need to change?  I made sure 
that the master were pointing to each other.

Below is my mirror mode configuration.

Machine 1 - IP Address 192.0.0.201

ServerID      1

overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100

syncrepl     rid=001
       provider=ldap://192.0.0.202:389
       type=refreshAndPersist
       interval=00:00:00:10
       retry="5 5 300 +"
       searchbase="dc=my,dc=domain,dc=com"
       scope=sub
       schemachecking=on
       bindmethod=simple
       binddn="cn=Manager,dc=my,dc=domain,dc=com"
       credentials=mypassword

mirrormode    on

Machine 2 - IP Address 192.0.0.202

ServerID      2

overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100

syncrepl     rid=001
       provider=ldap://192.0.0.201:389
       type=refreshAndPersist
       interval=00:00:00:10
       retry="5 5 300 +"
       searchbase="dc=my,dc=domain,dc=com"
       scope=sub
       schemachecking=on
       bindmethod=simple
       binddn="cn=Manager,dc=my,dc=domain,dc=com"
       credentials=mypassword

mirrormode    on

Thanks in advance.
