« HTML content follows »Dear List,We are trying to build a mail infrastructure with the following components: -1. postfix-2.3.3-2.1.el5_2 2. courier-authlib-pgsql-0.63.0-1.el5.mf courier-authlib-devel-0.63.0-1.el5.mf courier-authlib-userdb-0.63.0-1.el5.mf courier-authlib-ldap-0.63.0-1.el5.mf courier-imap-4.8.0-1.el5.mf courier-authlib-mysql-0.63.0-1.el5.mf courier-authlib-0.63.0-1.el5.mf 3. maildrop 4. cyrus-sasl-2.1.22-5.el5 5. Active Directory (Windows server 2008 R2)The OS is RHEL 5.5 (64 bits). For external mail transaction we have a mail gateway server with the same components as above except maildrop. This server is kept on the DMZ we are trying to configure the system in a way so that all POP clients coming from the Internet would hit the gateway server. The POP3 Proxy running at the mail gateway server would direct the traffic to the internal mail server and get the response back to the POP client.As the authentication is being done from the Windows AD server, we have added an attribute in the AD as mailHost and that attribute contains the fully qualified domain name of the mail server. The ldapsearch is returning the mailHost attribute without any problem. The FQDN of the mail server is responding to the ping request from the mail gateway server.The configuration that we have done are as follows:a) In the /etc/authlib/authldaprc file we have appended the line LDAP_AUXOPTIONS mailhost=mailHostThe content of the file is given herein for your reference LDAP_SERVER 172.16.2.14 LDAP_URI ldap://172.16.2.14 LDAP_PROTOCOL_VERSION 3 LDAP_BASEDN cn=users,dc=tibs, dc=edu, dc=in LDAP_BINDDN admin LDAP_BINDPW cescnet_123 LDAP_TIMEOUT 5 LDAP_AUTHBIND 1 LDAP_MAIL mail LDAP_DOMAIN tibs.edu.in LDAP_GLOB_UID vmail LDAP_GLOB_GID vmail LDAP_HOMEDIR unixHomeDirectory LDAP_MAILDIR unixHomeDirectory #LDAP_DEFAULTDELIVERY defaultDelivery LDAP_MAILDIRQUOTA mailQuotaSize LDAP_FULLNAME cn #LDAP_CLEARPW clearPassword LDAP_CRYPTPW userPassword LDAP_DEREF never LDAP_TLS 0LDAP_AUXOPTIONS mailhost=mailHostb) In the /usr/lib/courier-imap/etc/pop3d file we have set POP3_PROXY=1 and PROXY_HOSTNAME=wmd02.tibs.edu.inWhere wmd02.tibs.edu.in is the hostname of the mail gateway server.But with this configuration we are not being able to fetch mails using our mail gateway server.The log information is given below: - Jul 30 17:46:18 wmd02 authdaemond: binding to LDAP server as DN 'admin'Jul 30 17:46:18 wmd02 authdaemond: using search filter: (mail=jaya...@tibs.edu.in)Jul 30 17:46:18 wmd02 authdaemond: one entry returned, DN: CN=jayanta,CN=Users,DC=TIBS,DC=EDU,DC=INJul 30 17:46:18 wmd02 authdaemond: authldaplib: sysusername=<null>, sysuserid=500, sysgroupid=500, homedir=/home/vmail/tibs.edu.in/jayanta/Maildir, address=jayanta, fullname=jayanta, maildir=/home/vmail/tibs.edu.in/jayanta/Maildir, quota=<null>, options=mailHost=mail.tibs.edu.inJul 30 17:46:18 wmd02 authdaemond: rebinding with DN 'CN=jayanta,CN=Users,DC=TIBS,DC=EDU,DC=IN' to validate passwordJul 30 17:46:18 wmd02 authdaemond: authentication bind successfulJul 30 17:46:18 wmd02 authdaemond: Authenticated: sysusername=<null>, sysuserid=500, sysgroupid=500, homedir=/home/vmail/tibs.edu.in/jayanta/Maildir, address=jayanta, fullname=jayanta, maildir=/home/vmail/tibs.edu.in/jayanta/Maildir, quota=<null>, options=mailHost=mail.tibs.edu.in
That should be mailhost, not mailHost.
