LDAP Master and LDAP Replica!

[zibra]

Dear all,
I have a little confused in setup LDAP Replica for my zimbra. In multi-install document, i see that "For replica LDAP servers the status is changed to Disable" (in installation progress of LDAP configuration submenu). However, in the guide of LDAP replica installation, it only instructs to change "Create Domain:" to No which not set the Status of LDAP to Disable. (Zimbra doc 5).

I'm on ZCS 5.0.5. May be, there are some changes in version 4 and version 5 which not updated in Zimbra doc 5 yet.

Please help me to do the problem clearly.
