LDAP authentication

Hi,

I have a client using different webapp and they are using single signon with LDAP. I want the email hosted via centos web panel also authenticate using same credential.

Means when user logs in via roundcube. the authentication will be from LDAP server than local postfix mailserver.

Thanks you very much.

You can try to build it manually and set the auth method. By default, Postfix uses the database.
Check Postfix README: http://www.postfix.org/LDAP_README.html it has full information about the configuration
