Having pain with user authentication on your old legacy Unix servers? Here comes the solution: ID-Views via LDAP. If you need to preserve UID/GID or other stuff like shell on some legacy servers but want to have the benefits of a centrally managed identity management, then ID-Views is the answer.

Setting up IPA with a specific CA cert subject
If you are doing experiments with IPA where you install and reinstall IPA servers, you may notice SSL certificate errors when connecting to an IPA server using Firefox. The reason is that always the same Organization and serial is used when the CA cert is created. Normal users are usually only affected when using the same Realm and DNS subdomain for the test and production environment which is not recommended anyway. Reproducing the issue 1. Set up IPA with ipa-server-install. ….Read More

If you are using such things as webmail, it fails. This post shows you the capabilities as they are of today. ….Read More
Migrating legacy servers to FreeIPA authentication using ID-views
ID-Views are a new feature of FreeIPA4 which allows you to map UID/GID user/group names to another. This is a very handy solution when migrating legacy servers. There are legacy servers in the field with a lot of history. They have been migrated from one operating system to another since the last decade(s). It is unfortunately also not uncommon on those legacy servers to find software with hardcoded UID/GID and/or user/group names. Along with an unknown number of scripts installed ….Read More
Using IPA to provide automount maps for NFSv4 home directories
Since the invention of NFSv4, automount NFS home directories is secure. Since the invention of IPA, its easier to set up and maintain. This article guides you trough the steps needed to set it up.
