To Apply a Provisioned Group
A provisioning policy has users that can be provisioned, groups that can be provisioned...a provisioning interval is the frequency that an object is checked. It will apply once the policy is created, and then it will.
Best Practices
Removing Administrator Rights Policy,
After the initial removal of Administrator Rights, the interval should be anywhere between 1 to 7 days if the end user is not an administrator.
After the initial removal of Administrator Rights, the interval should be much shorter, anywhere from 30 minutes to 4 hours.
