It appears that the LDAP search query that Jitsi does is a wildcard search before and after the search string entered (givenname=\*SEARCH_STRING\*)
This brings back quite a few records and can be slow - due to the number of records returned.
Typically our users will start to type the first part of the users name and expect results to appear - i.e. wildcard search after entered text (givenname=SEARCH_STRING\*)
Is it possible to customise the search query in the sip-communicator.properties file at all???
