BASH Quotes examples BASH uses single quotes, double quotes and backticks. They all have their uses and using the wrong ones at the wrong time will cause unpredictable results. This page attempts to clarify their usage. Note, just to confuse new users, BASH uses $ as a normal user prompt as well as $ as a variable identifier.

Exim Configuration exim uses a single configuration file by default, /etc/exim/exim.conf. The config file is well documented internally and will work without modification in many cases, however we need to force all outbound mail via a Smart Host relay and but also allow local delivery via a pipe to local accounts (for the junkmail user). To accomplish this we need to alter the order of one mail router and add another.

LDAP and Microsoft's MAD In order to test using OpenLDAP with Microsoft's Active Directory (since MS insist on using Microsoft in every product name acronym, I will too, hence MAD=Microsoft Active Directory), I built a test server with win2k3 in it's own subdomain, ads.mydomain.pri. The server is authoritative for this subdomain.

LDAP (Lightweight Directory Access Protocol) [Open LDAP] LDAP is used by The Company on its production servers to authenticate users. Configuration is split into two parts, the LDAP server config and the LDAP client setup. The previous version of LDAP used dc=oldcompany,dc=com as it's base DN, but the new base DN is dc=int, dc=TheCompany dc=com.
