Application Configuration Access Protocol

The Application Configuration Access Protocol (ACAP) is a protocol which enhances IMAP by allowing the user to set up address books, user options, and other data for universal access.["Your E-Mail Is Obsolete", Byte, Feb 1997 ].ACAP grew to encompass several other areas, including bookmark management for web browsers - it's effectively a roaming protocol for Internet applications. ACAP is in use by at least four clients and three servers to varying degrees, but it has never gained the mindshare of Lightweight Directory Access Protocol. It's rumoured to be the most complex Internet Engineering Task Force designed protocol ever, which has caused serious problems for server implementors. It's also markedly similar to Lightweight Directory Access Protocol on some levels, which has caused confusion.

<protocol> (ACAP) A protocol which enhances IMAP by allowing the user to set up address books, user options, and other data for universal access. Currently (Feb 1997) no Internet proprietary products have implemented ACAP because the Internet Engineering Task Force has not yet approved the final specification. This was expected early in 1997.
