update dates not searchable in ActiveOffice / ActiveAgent resources

edit

I'm using phrets to connect, but I'm not able to search the ActiveAgent / ActiveOffice resources by modified date. I suspect this is the MLS messing up the credentials' access level?

2017-03-09 20:35:43 - INFO  --> Executing RETS query for Office - ActiveOffice - ActiveOffice - (O_UpdateDate=2006-01-01+) 
2017-03-09 20:35:43 - ERROR --> RETS error in getResources: 20207 : Unauthorized Query. You are not authorized access to the field [O_UpdateDate].

and

2017-03-09 20:35:44 - INFO  --> Executing RETS query for Agent - ActiveAgent - ActiveAgent - (U_UpdateDate=2006-01-01+) 
2017-03-09 20:35:44 - ERROR --> RETS error in getResources: 20207 : Unauthorized Query. You are not authorized access to the field [U_UpdateDate].

Any thoughts on this? Searching the Property resource by the same field works as expected.
