how does the search within the ACL picker work? On which field is it looking after?

I mounted the ACG13 LDAP directory. When now looking after the first name "AGNES" this retrieves a login name such as FAGNESE (ok) and FBOULANGER (why?). However this does retrieve the user ADUMAS for instance whom first name is Agnes.

So could we make an exhaustive search on all the "mounted" LDAP properties? Perhaps we could limit it to only the selected columns in the current views (but then we should be able to customize the ACL view and let users add new columns according to other user properties).

Else would it be possible to add some autocompletion? So that the GXT list is refreshed each time we are typing a new char (starting from a min of 3 char or something like that)?
