XADM: How to Determine When Permissions Have Been Altered in Exchange

MORE INFORMATION

The following event appears in the application log of the event viewer after an administrator has modified the permissions on one of these objects:

   Event ID 1175
   Source  MSExchangeDS
   Type  Information
   Category  Security
				

With the following descriptions:

• If the change is made at the Organizational level: Description: The Security attributes of object /o=<Organization Name> were modified.
• If the change is made at the Site level: Description: The Security attributes of object /o=<Organization Name>/ou=<Site Name> were modified.
• If the change is made at the Configuration level: Description: The Security attributes of object /o=<Organization Name>/ou=<Site Name>/cn=Configuration were modified.

With diagnostic logging set to Maximum on "Security" in the properties of Directory Service/Diagnostic Logging, the following event is logged:

   Event ID 1053
   Source MSExchangeDS
   Type Information
   Category Security
				

With the following descriptions:

• If the change is made at the Organizational level: Description: The security descriptor granted 0x80 access on object /o=<Organization Name> for this user.
• If the change is made at the Site level: Description: The security descriptor granted 0x80 access on object /o=<Organization Name>/ou=<Site Name> for this user.
• If the change is made at the Configuration level: Description: The security descriptor granted 0x80 access on object /o=<Organization Name>/ou=<Site Name>/cn=Configuration for this user.

In the previous Events, "admin" permissions were granted to a user; this equals "0x80" in the description. This number varies depending on which permissions were modified.

The description does not state which user made the modification to the objects; however, in the application log under the USER column, it states which user caused the event to be generated.
