Hi List,
  I want to setup following scenario.

1. Our office has two branches connected to Internet with static IP.
2. DNS are configured properly.
3. Each location will have one LDAP server and one qmail server.
4. LDAP servers between branches will be linked.
5. Requirement: local mails and remote mails should work fine when
connectivity is up and local mails should work and remote mails should
go to local queue if connecivity is down.

I have configured LDAP in following way (fedora directory server) with
smart referral.

Server A

basedn/root suffix: dc=example,dc=com
subsuffix: ou=chennai,dc=example,dc=com  with local database
subsuffix: ou=mumbai,dc=example,dc=com with smart referral to Server
A's ou=chennai branch

Server B

Vice versa in server B

LDAP queries (ldapsearch) working fine from both branches. And if
connecty is down only local record is displayed and for remote records
"time out" error occurs.

Qmail Configuration (in both brances)

ldapbasedn: dc=example,dc=com
ldaplogin: (local manager)
ldapserver: 127.0.0.1

when connectivity is fine, mails are going properly between branches.
But when connecvitiy is down, local mails getting delivered fine and
remote mails getting bounced saying "no such user".

How to get off the situtation.

Hope I have explained the situtation clearly.

TIA
Moorthy
