The readme you mentioned contains instructions on building the openldap client libraries from source, namely,

Code:

% ./configure  --without-kerberos --without-cyrus-sasl --without-tls \
    --without-threads --disable-slapd --disable-slurpd \
    --disable-debug --disable-shared

So, you can just get the source code from openldap.org and build your own, which is what I did. Works fine.

[edit: before compiling your own package, you should check your own distribution's package repositories to see if one is available. e.g. if you use Fedora, there is no need to compile your own, as there are RPMs available.]

ill be thankful to you that you shows your interest but
The link i have given with my problem is talking about package "postfix-ldap" which m not able to find.
And if i run that configure command on simple ldap package then it will not create file in /etc/postfix/
thats why m stuck here.

M working on Redhat Linux EL version and there is Ldap package already with it but there is no postfix scema in that..somehow i downloaded that scema, but still its not working.

Please help me if you tell me from where i get "postfix-ldap" package for LINUX. I have this package but for DEBIAN system.

ThankS

Postfix can be compiled to support various things: ldap, mysql, tls, etc.
postfix-ldap is simply a Debian package of postfix compiled with ldap support. Since you're using RedHat, you should probably not use the Debian package.

However, take a look at the output of the following command:

Code:

 postconf -m

If you see 'ldap' in the list, it means you already have support for ldap, so you're in business.

Once you have postfix with ldap support, you still need the ldap client libraries (so postfix can query an ldap server somewhere). For that you either find the appropriate rpm -- in Fedora, it's called openldap-clients, I think -- or compile them from source (that's what the ./configure... business in my previous post was about).

To summarize, there are two pieces of software that you need:
(1) postfix with ldap support (which you might already have)
(2) ldap client (which you might also already have -- check with 'rpm -q')

It looks like the postfix package you installed does not have support for ldap. You should look for the appropriate RPM at whatever official repository you use.

Your other question -- adding a mail attributes to ldap entries -- relates to the running an ldap server, something I don't know anything about. I do know how to query an ldap server using postfix, and the readme you mentioned has everything you need to know -- once you have a working ldap server. Sorry I can't be of any more help.
