Please I need help with ldap search filter to use to retrieve the user email information from ldap. I'm running postfix_ldap of Ubuntu server 12.04. Everything seems to work fine, except getting the values returned from the search.
Version 1
server_host = ldap://samba.example.com
search_base = dc=company, dc=example, dc=com
query_filter = mail=%s
bind = no
domain = example.com
Version 2
server_host = ldap://samba.example.com
search_base = dc=company, dc=example, dc=com
query_filter = mail=%s
bind_dn = cn=Users,dc=company,dc=example,dc=com
domain = example.com

My refined ldap-aliases.cf looks like this:
server_host = ldap://samba.example.com
server_port = 3268
search_base = dc=company, dc=example, dc=com
query_filter = mail=%s
result_attribute = uid
bind_dn = cn=Administrator,cn=Users,dc=company,dc=example,dc=com
bind_pw = pass
domain = example.com
So I'll like to know what ldap filter is appropriate to get this to work.
Thanks for helping out.
