[Owncloud] Heavy LDAP user search

[Jörn Friedrich Dreyer]

Just brainstorming: lucene by default only starts searching when the user has enterd three characters. Using the same limitation in the share dialog would allow Arthur to query the LDAP server with a filter that takes the three digits into account. That should drastically reduce lookup times and is not much of a nuisance to the user. The search dialog could then directly be populated with ldap results

@ Arthur: would that work or are there other requirements?
