fix

For Directory and Resource Administrator (DRA) versions 6.x, 7.0 and 7.0 SP1, the maximum interval that you can set the Incremental Accounts Cache Refresh schedule to through the GUI is 30 minutes.  If you go into the registry and modify the schedule to make it more often than every 30 minutes, DRA will still use 30 minutes as the interval.  

Beginning with DRA version 7.5, this interval has been lowered to 15 minutes.  It is not possible to lower the interval to less than 15 minutes.
