We are in the process of migrating our current AD domain to the coporate parent's domain. In our domain user accounts are named as FirstInitialLastname. In the corp. domain they use FirstName.LastName.
Now here's the problem..... There is a very old dos-based application that we run that cannot run when a user's name is longer than 8 characters. Is there a way to login to the corporate domain as Johnathan.Smith for example and somehow associate John.Doe in corp domain to JSmith in Local domain so that this app can run its configs etc... and start like it does now?
Keep in mind that we have no admin access to change any user attributes in the corp domain.
