after migrating mdb in the swingbox and installing 14.1 in the target-system I moved the mdb from swingbox to the target-system.
(mdb - task - restore)
From this point you cannot connect to mdb via mdbadmin.
The reason seems to be that the global sql-user mdbadmin remains in sql.
With the restore the mdb comes with it's own mdbamin.
Those do not fit together.
I removed mdbadmin and ServiceDesk user in sql security and mdb security and created them new in the sql security and assigned the roles/rights as necessary.
After that it worked.
Is there any other way to do that?
