This isn't possible with the standard OOTB AD service broker. You would need to create your own integration to do this, like a custom service broker or using one of the API brokers to connect to an API which provides this functionality.

Thanks Amolyneux. It seems there is a custom broker created by one of the developers. However, I am getting the "The directory service is unavailable" error while using update user method. Are you able to advise?

Thanks

Is this a custom broker that was created by a developer on your side? Or are you referring to a community broker like below:

Do other methods work? like a Read or List method?

The error seems to indicate no being able to connect to domain controller. What authentication method for service instance?

Does account have access?

Does service instance allow for configuration of domain/specific domain controller?

I used the Dynamic Active Directory Service solution.

Thanks
