due to it's current implementation (and pstring limitation), ldapsam does not
handle more then 15 password history entries. (tdbsam and NT do).
Any "password history"-account policy larger then 15 is silently reduced to 15.
Created attachment 1905 [details]
allow 24 password history entries in ldapsam (same limit as Windows)
Looks good to me - please apply Gunther !
Fixed in subversion.
