join not possible because computer already exists

To enable the net installer for a computer it must be added under devices. But a join is not possible for an existing computer. After deleting the computer the join is possible.
Did you use the same role? If you add the computer with the correct server role, it should work.
I had the wrong server role in my installation profile and I added the computer under ':/computers' and not under ':/computers/dc'. (If you add a dc in the wrong container the join fails because the '30univention-appcenter.inst' script fails with a timeout.) With the right settings the join works. It may be a nice future to have more precise error messages if a join fails because an already existing LDAP object conflicts with the settings on the computer that wants to join. But I think that is only a problem if you use the net installer, because usually there would be no preexisting LDAP object.
