good morning
I had the same problem, my client had two login users of AD, one for equipment and one for terminal services.
Were synchronized terminal services users, and settled by database, that was 2 months to 30 users and does not present problems and even when we use this query shows the problem.
the problem:
The User Cesar Echeverria have two AD users: Dominio\CesarE and Dominio\TSCesarE
Synchronized user by: Dominio\TSCesarE
the solution:
1. log into the SQL Server to the ProcessManager database and run this Query:
UPDATE[User]
SET ADLoginName = ' Dominio\CesarE'
whereADLoginName = ' Dominio\TSCesarE '
2. then go back and sync: ServiceDesk with AD.
I recommend that the test users have a separate OU, which is not in the profile ServiceDesk sincrinizacion
