Hello Rob, I just want to provide feedback that your command worked. I must have done something wrong initially. I am able to migrate all of the user private groups over to the new IPA - although it all became regular POSIX groups, at least I don't have to change permissions for 500+ users. Thanks very much!
Now my next goal is to try to do "ipa migrate-ds ..." into an Ansible task after a brand new IPA server install. Will be interesting to see how I can run this in an idempotent way ... Thanks Rob! --Tony On Thu, Apr 13, 2023 at 6:39 AM Rob Crittenden <[email protected]> wrote: > HUANG, TONY wrote: > > Hi Rob, > > > > Just curious, does your old-ipa-server have User Private Group disabled > > or enabled?
