What order are Policies applied? (4336543)

If 2 policies have conflicting settings, which one will be applied? Would any of the policies apply? What order are they applied in?

If 2 policies are conflicting, the last policy to be applied will override the settings from other policies in a conflict scenario.

The policies will apply in terms of tree order.

Example.
 

1. Management Unit 1 applies a validation policy to an attribute. Management Unit 2 applies a validation policy on the same attribute:
2. If MU1 applies the policy to OU 1, and MU2 applies policy to OU2. If OU2 a sub-container of OU1, then the policy applied to OU2 will override:
3. If both policies are applied to the same OU the order of policies being applied is same as the increasing order of name (CN) of APO links enforced to the OU. The names (CN) of the APO link can be checked by running the below query on Active Roles Configuration Database:

SELECT ap.edsaBlockingLink, apo.name,*
 FROM APOLinks ap join APOs apo
 on ap.edsaAPOGUID=apo.objectGUID
  where edsaSecObjectGUID in('GUID_OF_OU_GOES_HERE_e.g.- BE1B8494-C855-41E0-B639-A86E781F5177')
where the policy is applied
  and ap.edsaBlockingLink  <>1
 order by ap.name

Whichever policy's name (CN) is last alphabetically is the one being applied to the object.
