[Freeipa-devel] IPA 3.0 migrated to 4.1 users break winsync agreement when deleted in active directory

[Martin Kosek]

Hmm, does this mean we need to update our HowTo on migrating FreeIPA to FreeIPA
via migrate-ds? It is already quite long command, mostly due to the need of
removing Kerberos attributes:

The problem was that migrate-ds copied the attribute mepManagedEntry on migration, the suggested workaround, running migrate-ds with --user-ignore-attribute=mepManagedEntry --user-ignore-objectclass=mepOriginEntry worked like a charm (Thanks Rob!), deleting users in active directory doesn't break the winsync agreement and I'm able to delete migrated users directly in ipa. As mentioned in the bug comments, migrate-ds isn't really for ipa to ipa migration. However, it kind of worked...
