Is there a function in the admin api that performs a user synchronization?
Basically I'm looking for the equivalent of right clicking on a user in
console one, choosing groupwise utilities and then choosing synchronize.

The reason I'm asking this is that I'm adding users to an external post
office. When I'm connected to the domain that controls that external post
office, I see the changes I make. However, I have to manually go into
console one to synchronize the users to push these changes to the other
domains for some reason.
