Assuming it's fairly chaotic across your systems. You may just need to brute-force it. Before adding to IPA, you'll just need to map oldGID->newGID, then do something like find/exec/chown. You can do the same with groups. If you want to get fancier, have the script do the mapping.

Oh yes, it's clear, but I just don't know if I'm setting myself up for problems if I set a freeipa gid or uid to a value that already existed on the host before it was turned into a freeipa client.  That's already a problem with my users since they have different uids on the hosts if they were useradd-ed in a different order.  However I'm sure that if I just change uids in the /etc/passwd file to match freeipa then all the existing file ownerships will be messed up. 

I was hoping there is a standard way to deal with this and that I just didn't find the right page in the docs.

You can specify the GID when you create user groups in freeIPA.
In the GUI it's very clear (Group name[required], Description, Group Type, GID).
CLI it's something like # ipa group-add <group name> --gid=<GID>

Hi I'm trying to figure out the best practice for groups on my client servers.
I have several computation workstation hosts that have been added as freeipa clients, and several engineers who want to run docker on them
Members of the 'docker' group (gid=999 on some machines, for example) can run docker without needing sudo, which is what I want to roll out to all machines.  Ideally this would be managed from freeipa with LDAP groups, and so anyone in the 'engineers' group should also be a member of the 'docker' group.

When I create a 'docker' group on freeIPA it will have some other gid and the client sees that.
Should I just delete the original docker group from my hosts and let it get it from ldap, or should I go into /etc/group and change the gid to the one that matches the right ldap gid, or preferably something easier than that?
