Install And Configure OpenLDAP On Ubuntu Karmic Koala

Comments: 29 Install And Configure OpenLDAP On Ubuntu Karmic Koala The configuration of OpenLDAP got a bit (more) complicated. cn=config is still used, but when installing the packages from the repositories only a skeleton configuration of openldap is installed. You're not asked anymore to provide a password when the package is installed and issuing the "dpkg-reconfigure slapd" only resets openldap to the skeleton configuration. You will have to set up the openldap database, root dn and acl's yourself using the root account (or sudo) in order to configure openldap. Here is how I configured openldap in Karmic Koala, but I do not issue any guarantee that this setup will suit your needs or works for you as it worked for me.

Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS

Comments: 19 Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS I've been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature (amongst others) I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time (including crying, swearing, getting depressed, ...) to put it all together and get it working. Long live google to find hints or explanations for problems and configuration issues. Piecing it all together wasn't simple so I would like to share how I configured it and got it all working toghether (as I like), but I think that it will benefit other users as well.
