Summary
We are working toward moving away from 389 Directory Server, and to FreeIPA, as an Authentication and Identity solution.
Overview of Migration
- Establish VPN link between our existing web server and the space (complete)
- Set up new FreeIPA server (complete)
- Get proper monitoring in place to verify that VPN link is live. (complete)
- Remove all POSIX attributes from the directory (complete)
- Add POSIX information to everyone in the existing directory (see https://gist.github.com/cswingler/1b7c731c7a858791aff3) (complete)
- Flip the read-only flag on in 389-ds (complete)
- Get backups running on FreeIPA (complete)
- Purge existing users out of FreeIPA (complete)
- Change the ID range in FreeIPA to start at 1215100000 (not a compatible option, skipping)
- Use FreeIPA migration tools to migrate data from 389-ds into FreeIPA (complete)
- Disconnect clients from 389-ds (complete)
- Set up FreeIPA's Migration Webpage (https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/Identity_Management_Guide/#webpage-pwd-migr) (complete)
- Instruct users to visit the migration webpage to update their password (send out email, edit login page on wiki) - Login page edited, delaying sending out email as it's not necessary to be handled right away
- Reconfigure clients to talk to FreeIPA; test. (complete, success)
- Shut down 389-ds (complete)
- Remove 389-ds software from sshc0
- Set up replica of FreeIPA server in space on public server (to tolerate outages of internet or power at space)
- Complete.
Rollback Procedure
Up until the step "Remove 389-ds software from sshc0"; we should be able to roll back out of this process by:
- Turning 389-ds back on on sshc0
- Restoring previous configuration of clients.
Rollback not necessary.
Prepration steps
Staging
- Set up a 389-ds server
- Restore a backup of 389-ds
- Validate backup
- Set up a FreeIPA server
- Test migration tools
