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

[Andreas Calminder]

Hi,
I just wanted to post the solution for this, I've reported this to Redhat and a bug has been filed (https://bugzilla.redhat.com/1261536). 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...

Yes, kind of. I wanted a new environment with a proper certificate authority setup with only the old users and groups from the IPA 3.0 environment. The old environment use a self signed ca, I thought it would be easier to just migrate my users and groups.

Migrated users don't get user-private groups created.

Is there a reason you migrated from 3.0 to 4.1 rather than just adding a
4.1 master to the existing pool?
