Ticket 47427 - Overflow in nsslapd-disk-monitoring-threshold
Bug Description: Using ldapsearch shows threshold value as a negative number, even
though the feature is working correctly.
Fix Description: When reading the dse, the server was trying to cast the value as a "int".
Changed CONFIG_INT to CONFIG_LONG for nsslapd-disk-monioring-threshold.
