I configured POSTFIX with DOVECOT, LDAP & Squirrel mail on RHEL 5.5.
Iam able to login using LDAP authentication.
Now i want to deliver mails locally using LDAP.
I configured to query LDAP using transport lookup table (ie.transport_maps=ldap:ldaptransport).
it shows the following errors:

warning:dict_ldap_lookup:ldaptransport : search base not found-no such object..
Temporary lookup failure.



ldaptransport Configuration:
server_host=hostname of server
search_base=ou=people,o=lpscm
result_filter=relay:%s
query_filter=(&(Email=%s)(accountStatus=enabled))
result_attribute=mailHost

(But same search_base is configure in Dovecot, it is authenticating)

I have searched in net, they are telling that some ASCII encoding problem in postfix to LDAP.

But Solution..........................?????????????

Any one help me...............
