Overview

EUDC, the Emacs Unified Directory Client, provides a common user interface to access directory servers using different directory protocols.

Currently supported back-ends are:

• LDAP, Lightweight Directory Access Protocol
• BBDB, Big Brother’s Insidious Database
• macOS Contacts
• ecomplete, Emacs’s electrical completion
• mailabbrev, Emacs’s abbrev-expansion of mail aliases

The main features of the EUDC interface are:

• Queries using a customizable form
• Inline query expansion (for instance you can expand a name to an email address in a mail message buffer using a server as an address book)
• Multiple servers can be tried in turn until a match is found for an inline query
• Fast minibuffer queries for email addresses and phone numbers
• Interface to BBDB to let you insert server records into your own BBDB database (see BBDB in BBDB Manual)
