r26419: Add a module to implement 'ambigious name resolution' by munging the
incoming LDAP filter.
Warning: Any anr search will perform a full index search. Untill ldb
gets substring indexes, this is unavoidable.
Also implement a testsutie to show we match AD behaviour for this
important extension (used in the Active Directory Users and Computers
MMC plugin, as a genereral 'find').
This will also be useful to OpenChange, as their server needs to
implement this.
